LAN Power Supply 5 Amp (RS485)

The CM723B LAN Power Supply is a high efficiency 13.8V DC, 5Amp continuous rated switch mode power supply with two independent battery chargers. The battery chargers can be configured to charge one or two 7.2Ah batteries, or for longer standby times they can be combined to charge a single 18Ah sealed lead battery. Two power output terminals are provided to simplify wiring to ancillary equipment and these are protected with a self resetting fuse. An optional CM435 Power Terminal Expander card can be used to increase the number of terminals if required.

The CM723B is a LAN device and can be installed in its own enclosure away from the Solution 144 control panel, while remaining fully supervised. Once connected via the RS485 encrypted LAN, the panel continuously monitors all functions of the power supply including AC power fail, low battery, output voltage, current overload conditions and even its own temperature. Should any problems be detected, the system will display a trouble message on the keypad as well as report the event to the monitoring station so they can take appropriate action.
