These form the central building block when designing battery backed DC power supplies. The heat-sink assembly with power rectifiers, steering diodes and monitoring circuitry are all built on a single chassis for ease of mounting. Simply add the Batteries and BCS series power supply/chargers to achieve the required charging and power supply characteristics. The battery is continuously monitored for Low voltage and Charge Fail with separate status LED’s and fail-safe, volt-free alarm contacts.
A green LED indicates that conditions are normal with both relays energised. That is, the Battery is charging and its voltage is within limits. Versions are available for 12, 24 and 48V systems.
