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
10.6 ± 0.15 Vdc at heavy loads (more than
150 W) or 10.8 Vdc at light loads (less than
150 W) for more than 4 min and 10 sec
(± 30 s)
2. Battery voltage is below 10.4 ± 0.2 Vdc for
3 seconds
DC low voltage restart 13.0 ± 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.
