The SRU-UPS can pass through up to 60W (12V/5A) from its power input to the CPU board and peripheral cards, reasonable for small to medium systems. When a power fail situation occurs, the SRU-UPS sustains full power on its output for >10s, sufficient for a normal shutdown of the operating system without loss of data.

The SRU-UPS is equipped with a PwrBlade® backplane connector. EKF offers suitable CompactPCI® Serial backplanes with two adjacent PwrBlade® slots for both a removable power supply and the SRU-UPS card.
