When the engine is switched on, the Voltage Sensitive Relay stays open until the starting battery reaches 13.7/27 V and then closes the contact and charges the 2 batteries at the same time. When the engine stops and the voltage drops below 12.8/25.2 V, the Voltage Sensitive Relay opens the contact and keeps the two batteries separated thus preventing the wrong battery from draining and avoiding current peaks that damage the onboard electronic equipment when starting the engine. It protects the starter battery from draining due to the use of onboard services. No voltage drop, zero consumption in stand by phase. Easy to install without modifying the alternator cabling. 12/24 V automatic selection. Battery charger Code V A Description mm 14.921.90 12/24 140 Voltage-sensible relay 68x68x50 VSR Voltage Sensitive Relay with Starter isolator When the voltage of start battery reaches 13.7/27.0 V, the smart battery isolator (SBI) keeps engaging, and two batteries are charged simultaneously. When the engine is off and the voltage drops below12.8/25.5 V, the SBI senses it and disengages, separating both batteries, avoiding to drain the wrong battery. When the voltage of the start battery drops the isolator kit disengages from charging the auxiliary battery. This isolates the start battery and eliminates the possibility of draining it, ensuring that you always have enough charge to start your engine. No voltage drop. 0.5 m/A current draw in stand-by mode. LED warning light when VSR is activated and 12/24 V automatic selection. Functions: - Start Isolation: it engages temporary isolation during the engine ignition to protect the onboard instrumentation. (*) - ABE: when the engine is at a minimum rate, it loads both batteries for an additional period of time lowering the disengaging level from 12.8/25.5 V to 12.2/24.5 V. (*) - Storage Mode: current draw reduced to 0 when the engine is still. (*) - ON-OFF manual activation is possible. - Front contacts (10 mm) for easier installation + clear protection lid. (*OPTIONAL functions, to be activated only if you wish it). Battery chargers Code V A Description mm continuous intermittent 14.921.91 12/24 125 140 Voltage-sensible relay -
