may be increased to PSU rated current
Battery reverse connection will open internal
fuse (and produce alarm)
Detects for presence of battery on start up,
then every 60 minutes when charge current <
200mA
Electronic Circuit Breaker (ECB) operates
under the following conditions:
ELVD (electronic low voltage disconnect)
activates when battery voltage drops to 1.67V/
cell (adjustable) - auto reset
Allows ~150% load from battery without act-
ing, operates within 300ms for total load >
600%
Acts within 2ms, backed up by fuse
Green:
Battery System OK, Power OK
Red:
