BEP 100/125A Voltage Sensitive RelaysBEP 710-125A and BEP 710-100A-24 Voltage Sensitive Relays (VSR's) allow two or more batteries to be charged at the same time in 12V and 24V systems respectively. Charge current is fed first to the starting battery, rated for continuous current 12V 125A, intermittent current 12V 150A and 24V 100A, intermittent current 24V 125A. Ignition protected to UL1107. The relay is connected between the start and house batteries and is at first open when the engine is started and remains open during charging until the starting battery has reached the preset voltage of 13.7V (27,4V). The relay then closes, allowing the two batteries to be charged together. When the charging is stopped and in time the voltage falls to below 12,8V (25,6V) the relay disengages again, separating the two batteries and eliminating the possibility of house loads discharging the starting battery. These VSR's fit into the same modular locking system as the 150003 battery switch. The dual sensing 710-125A-DS 12V VSR senses the state of charge of both battery banks, therefore enabling either battery to feed charge to the other within the same parameters as above, i.e. an activation voltage of 13,7V and a cutout of 12,8V. This is particularly useful to charge the start battery if other charging sources such as solar panels, wind generators or AC battery chargers are used to feed charge to the house bank. Note that the use of the dual sense VSR means that house loads could be subject to starting voltage spikes - sensitive equipment should be turned off during engine starting. |

BEP 300A Voltage Sensitive RelaysBEP 300A dual sensing Voltage Sensitive Relays (VSR's) have the same characteristics as the 100A VSR's and are available for 12V and 24V systems. They have the dual sensing function as standard. In addition they can be used as parallelling solenoids for emergency starting. The parallelling function will parallel the batteries for 10 minutes and can be operated by means of the selector switch fitted to the unit or a remote mounted push button switch. Unless the battery voltage is then above the normal cutout voltage for the VSR, the relay will be released after 10 minutes. It is possible to use the unit purely as a paralelling solenoid by not connecting the battery sense cable. |

BEP 275A Voltage Sensitive Motor Driven SwitchesThe BEP 720MDVS has the same characteristics as the 701-MDVS above (160). The 720-MDVS is rated 500A continuous (1h), 700A (5min) intermittent, cranking 2500A (10s). Dimensions 102mmx102mmx110mm high, fastening holes d5,5mm in 89,4mm square. Flush mountable in a 85mm cutout (protrusion 59mm, intrusion 51mm). Studs M12 tin plated copper. For flush mounting plates see 150906 etc. The BEP High Current remote operated voltage sensitive switches combine the features of the remote operated battery switches with those of the voltage sensitive relays (VSR's). The 701-MDVS and 720-MDVS can be operated through a momentary switch on the dash and will instigate a preset time of 10 minutes. Once these 10 minutes have passed, if the voltage is up high enough for the voltage sensitive relay to operate, it will stay engaged. If not, it will disengage. The VSS will engage when the voltage on either the start or the house battery reaches 13,7V. If the combined battery voltage drops below 13,0V and the engine is not running, after 5 seconds the contacts will open and stay open until the start or house battery voltage is greater than 13.7V. If the combined battery voltage drops below 12,2V and the engine is running, after 5 minutes the contacts will open and stay open until the start or house battery voltage is greater than 13,7V. If voltage drops below 13V and stays above 12,2V on either start or house battery while engine is running, the VSS will stay engaged. The 24V switches engage at 27,4V and disengage at 24,4V. The motor switches operate at voltages of 8V to 15V and 15V to 24V. The switches can be manually overriden. The advantage of using a high current VSS is that it will cover your dual battery charging requirements and emergency parallel operation in one unit. The 701-MDVS is rated 275A continuous (1h), 455A intermittent (5min), 1250A cranking (10s). Dimensions 69mmx69mmx100mm high, fastening holes d5,5mm in 54,5mm square. Flush mountable in a 52mm cutout (pro |
BALMAR Digital Duo Charge Battery CombinerThe BALMAR Digital Duo Charge is a battery combiner for charging starting or other secondary batteries. Instead of solenoids, the Digital Duo Charge employs mosfet solid state technology to avoid any voltage losses. It draws some of the current being fed to the house battery from one or more charging sources to charge the secondary battery. The BALMAR Digital Duo Charge caps charging current to the second battery battery to 30A. Four pre-set programs for FLA starting batteries, FLA deep cycle batteries, Gel batteries and AGM batteries are available to control cut-in voltage and upper voltage limits. In addition, it is possible to create a custom charging regime by manually selecting upper and lower voltage thresholds between which charging will take place. There is no current control other than the 30A upper limit. Should higher charging currents be required, the BALMAR Digital Duo Charge can be used to control an external solenoid (not supplied). This series regulator is fully enclosed in a potted (epoxy encapsulated) housing. Programming is by actuation of a reed switch encased in the unit by means of a magnetic probe. An optional battery temperature sensor (part number 105905) can be connected to the BALMAR Digital Duo Charge for it to monitor and respond to excessive battery temperatures. |

AMPLE POWER Isolator Eliminator Series regulatorWhen a manual switch, a paralleling relay, voltage sensitive relay, a diode-isolator or a mosfet-isolator are used to charge house and starter batteries together, chances are high that that the starter battery will soon be fully charged and the continued high charge current and voltage required for a regulated charging source to fully charge the house battery will cause an overcharge and damage to the starter battery. Alternatively, the house battery could never reach fully charged level. Diode isolators also present inherent problems such as excessive voltage drops that, without special regulators, prevent full charging For these reasons, charging the secondary battery by means of a smart, series regulator is an interesting alternative. The series regulator is connected to the house battery and siphons some of the current from any charge source feeding the house bank to the starting battery. It is possible to without any compromises regulate charge in a way to optimally meet the requirements of the starting battery, whilst the requirements of the house battery can be the sole focus of the smart regulator of the primary charging source controlling the charging of the house battery. In doing so, undercharges or overcharges of the starting battery typical of paralleling switches or solenoids, voltage sensitive relays and diode or mosfet-isolators are eliminated. Unlike a manual switch, a paralleling relay, voltage sensitive relay, a diode-isolator or a mosfet-isolator, the AMPLE POWER IsolatorEliminator is able to limit current as well as turn it off completely. Limiting current is particularly important in a situation where a large house battery is being charged from a high current charging source, but the starting battery is relatively small, as high charging currents could damage the starting battery. Ideally, the reserve battery is used for nothing except the starter motor. All other loads are drawn from the deep cycle bank, and all charge sources are connected directly to it as well. The AMPLE POWER IsolatorEliminator is the perfect companion to inverters with battery chargers, since many such chargers can only charge one bank. The AMPLE POWER IsolatorEliminator is a multi-step series regulator with the purpose of tending to the starter battery. The AMPLE POWER IsolatorEliminator connects between the house and starter banks, maintaining the correct charge level on the starter bank while the house bank is being charged from alternators, battery chargers, solar panels, wind generators or other charging devices. A microcomputer controls a multi-step charge process that restores a full charge without allowing overcharge. The AMPLE POWER IsolatorEliminator is fully automatic and can even be left operating when the house bank is equalized to 16+ Volts. Battery temperature sensing is standard and protects batteries in hot or cold weather. Used properly, the AMPLE POWER IsolatorEliminator will keep any starter battery topped up and ready to crank. The AMPLE POWER IsolatorEliminator also controls the direction of current flow and will not let current flow from the starter battery back toward the charge source. The temperature sensor adjusts charge voltage over a range from -20ﾰ to 60ﾰC. In colder climates, the AMPLE POWER IsolatorEliminator maintains a higher voltage than it does in hot ambient temperatures. Above 60ﾰC battery temperature, the AMPLE POWER IsolatorEliminator shuts off completely, perhaps avoiding thermal run-away of the starter battery. The AMPLE POWER IsolatorEliminator thus determines the final voltage on the battery, temperature compensated. The AMPLE POWER IsolatorEliminator is safer, and will extend battery life and reduce water maintenance. In the final analysis, cost of ownership is less with the AMPLE POWER IsolatorEliminator than with a manual switch, a paralleling relay, a voltage sensitive relay, a diode-isolator or a mosfet-isolator. The AMPLE POWER IsolatorEliminator reduces system complexity. In it's standard configuration the AMPLE POWER IsolatorEliminator has a charging regimen suited to FLA (flooded lead acid) batteries. However, a setting for lower charging voltages suitable to VRLA batteries (GEL or AGM) can be selected. The unit has a built in LED status/error indicator, with the option of fitting a remote mounted indicator light or alarm. Dimensions are 163mm x 158mm x 56mm(h). The unit can be mounted in any orientation. Connection to the Eliminator is by means of ring terminals under tin- plated brass screws. |

XANTREX Echo-Charge Series regulatorXANTREX Digital Echo~Charge is designed to charge auxiliary or starting batteries by diverting some of the current flowing from a charging source to a house battery. The XANTREX Digital Echo~Charge follows the voltage of the charging source up to a maximum of 14,4/28,8V. The maximum charging current offered by the XANTREX Echo~Charge is limited to 15A, which it maintains if the voltage of the secondary battery is between one and two Volt below that of the primary battery. For greater or lesser Voltage differences the charging current is progressively reduced. Xantrex Digital Echo~Charge automatically adjusts for 12 or 24 Volt battery banks and switches on/off without affecting the in-house battery bank. Echo~Charge is protected by thermal and over-current circuits and against reverse polarity connection. Easy three wire installation! Because the XANTREX Digital Echo~Charge follows the voltage that the primary battery is being charged at, it is most suitable for use when the starting battery is of the same type as the house battery. Care should be taken when charging batteries of a type that differs from that of the house battery, as the charging voltage could be inappropriate. |
