Electronically controlled relay for simultaneous charging of two batteries. The ACR isolating relay is installed between the first and second battery. The relay remains open until the charge level of one of the batteries reaches a predetermined voltage value. Now the relay closes and both batteries are fully charged. When the engine is switched off and the voltage drops below a certain value, the relay automatically opens and ensures the electrical isolation of the batteries. Ideally suited, also for connecting an alternator and charger, if only one output is available in each case. The relay has a connection for automatic disconnection of the batteries when the engine starts and a connection for a control LED.
System voltage: 12 / 24 V DC (automatic detection)
Max. load capacity (<5 min.): 210 A
Max. continuous current: 120 A
Connection Ø: M10
Switch-on threshold (30 sec.) 13.6 / 27.2 V DC; (2 min.) 13.0 / 26.0 V DC
Switch-off threshold (10 sec.) 12.35 / 24.7 V DC; (30 sec.) 12.75 / 25.5 V DC
If 16.0 / 30.0 V DC is exceeded, the relay automatically opens

FAQ
Yes, this is possible. For this, the required fuse size per circuit must be specified when ordering the switch panel.
Yes, before each switchboard, a main fuse must be integrated into the supply line to the switchboard near the battery.
Yes, all common sensors used in the marine and automotive sectors can be connected.
