The AWZ633 battery controller is designed for monitoring the status of the (Capacity: 7÷40Ah/12V (SLA)) 2 batteries pack based on the measurements of resistance, continuity of the batteries circuit, voltage, and the charge level. It is also protected against reverse connection and short circuit in the charging circuit. In the case of failure, a LED light is activated, which is accompanied by switching of relay contacts and acoustic indication. Destination: To monitor condition of battery/batteries by measuring resistance, continuity of the battery/batteries circuit, voltage and charge level. Short circuit protection and reverse battery connection. Acoustic indication of failure, LED diode and switching relay on. Input: BAT – terminals for connecting external batteries. Output: PSU – terminals for connecting uninterruptible power supply unit (BAT output of power supply). Maximum current: 10Amp. Fuse type: glass fuse – 1x15Amp. Battery: 2x7÷40Ah. Technical outputs relay type: ALARM – collective failure. Acoustic indication of failure – BUZZER – possibility of switching on / off. Mounting dimensions: W=108, H=38, L=80 [+/- 2mm].
