SRU-UPS

Board Mount UPS

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.

For UPS specifications please refer to the datasheet

Special Features
  • FCI/Amphenol PwrBlade® backplane header, 9x power 24x signal contacts
  • Pin assignment similar to nVent and Trenew removable power supplies (AC contacts = NC)
  • COTS CompactPCI® Serial backplane available with two adjacent (8HP pitch) PwrBlade® slots for removable power supply and and SRU-UPS (EKF part no. 932.8.04.998)
  • Backplane usage is scalable - if an UPS is not required power supply can be moved into UPS slot
  • Custom backplane solutions CompactPCI® Serial or other Eurocard based available on request
  • Front handle micro-switch can be used as system power button replacement
Applications
  • Short time backup solution e.g. bridging the time gap from general power failure to emergency generator startup
  • Can be used to backup the system until normal shutdown of the operating system has been accomplished (shutdown initiated by power fail output signal from PSU or UPS)
  • System reliability enhancement for critical mains supply
