Bistable automatic relay for simultaneous charging of two large battery banks. The ML cut-off relay is installed between the first and the second battery. The relay remains open until the filling level of one of the two batteries reaches a preset voltage value. Now the relay closes and both batteries are fully charged. When the machine is switched off and the voltage drops below a certain value, the relay opens automatically and ensures the electrical disconnection of the batteries. Due to the bistable magnetic interlock, the intrinsic current consumption of the ML relay is extremely low.
Remote and manual parallel connection for emergency starting
500 amp continuous rating, suitable for use with high power alternators
Magnetic latching – very low continuous current consumption (<40 mA in “ON” or “OFF” position).
Works in both directions – ideally suited, also for connecting alternator and charger when only one output is available at a time.
Connection for control LED – to indicate the switching status on the control panel.
Tin-plated copper connection bolts, M10
Contacts made of a silver alloy, for long life and maximum reliability
Maximum load capacity: <10 sec. =2,500 A, <1 min. = 1,100 A, <5 min. = 700 A
Close switching threshold (30 sec.) 13.5V DC; (90 sec.) 13.0V DC
Disconnect switching threshold (10 sec.) 12.35V DC; (30 sec.) 12.75V DC
If 16.2V DC is exceeded, the relay opens automatically
