DC Distribution:
Load: 16 breaker position capacity, available amperages (specify) 6A, 10A, 20A, 30 amp, with tripped breaker alarm
Battery: 2 x 100A battery circuit breakers.
Breaker Fail Detection: Electronic fail detection on both load and battery. Breakers
Low Voltage Battery Disconnect: 125A battery LVD installed standard, with disconnect alarm

Monitoring & Control:
Monitors all power system conditions including DC voltage, rectifier current, battery current, battery temperature, and distribution failure.
Visual notification of alarm conditions by LED's and a 4 line x 16 character alpha numeric display mounted on the front panel, with remote notification being enabled by relay contacts, RS232 or TCP/IP (using SNMP). It has a built-in web based configurator allowing setup of
system parameters using a web browser and utilizes a USB communications port which allows for local monitoring of
system operations as well as easy downloading of configuration files for multiple site installations.
