The power supply provides full condition and fault monitoring to the system via the FIM (used by the PSB800M) or addressable power supply monitor APM800 (used by the PSM800). The PSB800M incorporates the LBM800 booster module to provide the correct voltage levels to maximise the performance of the MZX DIGITAL protocol.
Fault signals (Loss of AC, Battery charger fault, Battery fault) and control inputs (Battery test, Output reset) are provided. Battery voltage and charger current readings are also provided to the FIM or APM for automatic battery testing.
Screw terminals provide 2 x 24V outputs (24 V stabilised, 24V stabilised with reset control) and one 5V output.
The power supply is fitted in a steel cage with mounting points to allow any of the following boards to be mounted:
- APM800 addressable power supply monitor
- FB800 fuse board with 15 x 24Vd.c. fused spurs
- IOB800 input/output expansion board
