Weidmuller Battery Back Up Units for DC Power Management

Weidmuller's Battery Back Up Unit (BBU) is designed to be the heart of an uninterruptible DC power management system. The connectPower BBU combines with Weidmuller power supplies and a customer-supplied battery pack to form a scalable DC power system. This enables users to put together a system uniquely tailored to their needs.

These full-featured units have all the diagnostics needed to monitor the status of the power system. These DC power management units interface with the DC power supplies in the control cabinet. In addition, they monitor the status of the DC loads and the DC batteries. If the AC is removed or experiences a voltage sag, the load is switched seamlessly to the batteries. When the AC line is restored, the batteries are recharged and maintained.

With the BBU Power Supply, 2A of battery charging current is available at 24VDC, and 3A with the 12VDC units. Extensive monitoring is provided via LEDs. Relay contacts provide battery status indication and fault indication.
