Charger specifications
All charging specifications are at nominal conditions, 77 °F (25 °C), 14.0
Vdc at 50 A charging, 120 Vac, 60 Hz unless otherwise specified.
Shutdowns and Restarts
DC low voltage shutdown 1. Battery voltage drops below 11.8 ±0.15
Vdc at heavy loads (more than 150 W) or
12.3 Vdc at light loads (less than 150 W)
for more than 4 min and 10 sec (± 30 s)
2. Battery voltage is below 10.5 ± 0.2 Vdc for
3 seconds
DC low voltage restart 12.5 ± 0.15 Vdc
DC high voltage shutdown 16.0 ± 0.2 Vdc
DC high voltage restart Less than 16.0 Vdc, same as DC high voltage
shutdown; there is no hysteresis
