The PH28 is a pulse width modulated ac to dc power converter that provides regulated 4-28 Vdc output with up to 10 amperes continuous output current.This converter is primarily designed for 115V/400 Hz aircraft systems to deliver variable 4 to 28 Vdc power to incandescent lamps or LED loads for airborne/ground instruments, navigation and electronic systems.The unit can also be used as a fixed output voltage source between 14 Vdc and 28 Vdc.
The DC output is factory calibrated to 28 Vdc at the receptacle for a 10 amp load.The output voltage level is controlled manually by the duration of grounding the Dim or Bright control pin through an external momentary On-Off toggle switch.
