This forms a complete 7AHr Battery Backed DC Supply. The 12V and 24V versions incorporate a single chassis holding one or two 12V 7AHr Batteries, monitoring circuitry and a combined switch-mode Power Supply and Battery Charger. The Batteries are continuously monitored for Low voltage and true Charge Failure with separate status LED’s and fail-safe, volt-free alarm contacts. A green LED indicates that conditions are normal with both relays energized. That is, the Batteries are charging and their voltage is within limits. In the event of a mains failure, the Battery power is switched into circuit to power the load.

Note: the 48Vdc version includes an additional chassis to carry the two extra 12V Batteries.
