The SRU-UPS is a power backup unit, housed on a 100x160mm2 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.
