SRU-UPS

CompactPCI® Serial • Board Mount UPS

The SRU-UPS is a power backup unit, housed on a 3U Eurocard, suitable e.g. for CompactPCI® Serial backplanes or other 19-inch based systems. Intended for use in addition (in-line) to a PSU, it can be regarded as uninterruptible power supply (UPS).

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 also a backup solution for short power failures. During normal operation, the input voltage is forwarded to the SRU-UPS output with a small loss of <0.3V. When the UPS detects an under-voltage condition (<11.5V) on its power input, output power will be generated by a DC/DC converter instead, derived from an array of on-board ultra capacitors.

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.
