- FLAME DETECTOR POWER SUPPLY
The IS22OPSFDH1A is a Flame Detector Power Supply manufactured by General Electric as part of the Mark VI Series used in gas turbine control systems. The primary gas turbine trip protection (TRPG) terminal board is normally mounted above the Flame Detector Power Supply (PSFD).
A power distribution board provides 28 V dc as the source power (JPDL). 335 V dc, 5 mA is the output's rated rating. Up to eight flame detectors can be powered by three power supplies linked in a diode-ORed, TMR arrangement to the TRPG's J3, J4, and J5.
Even during a direct short, the output limiter limits the current to 7 mA. Even in an environment that is 65 C(149 °F), the output can remain shorted indefinitely. At the output, transient protection is provided by a 385 V MOv.
