LVD drive
The controller has 2 LVD drive outputs that can drive two bi-stable / mono-stable contactors.
1. Bi-stable Contactor: 2A maximum drive current with drive pulse width of 500ms ~ 1s.
2. Mono-stable Contactor: 3A maximum starting current and 1A maximum holding current.
1.3.2 Display And Indicating Functions
The controller has a green LED for indicating operating status, a yellow LED for indicating observation alarm, and a
red LED for indicating major and critical alarms. It also provides a drive output for alarm LED on a system cabinet.
The controller LCD can display the AC parameters, DC parameters, rectifier and battery parameters, operating status,
alarm status, settings, and control parameters.
