Flywell Power's PS30M and PS50M miniature power supplies are lightweight combination charger / power supplies able to deliver 30 or 50 A depending on model, at a pre-set voltage between 28 and 31.5 V (for 28 V charging) as selected by the operator. Power supplies can be connected directly to the aircraft's external ground power receptacle or to any of FWP's portable starter GPUs.
The PS30M / PS50M are designed for operators of smaller helicopters and VLJs needing to download data or program avionics in any location where size and weight are important.
The auto selecting 120 / 240 V, 50 / 60 Hz input allows international use. A solid state voltmeter displays the output voltage when the unit is operating. Coloured LEDs confirm mode selection. A green and red LED indicates amperage below or above current limit protection.
Unique to the PS30M / PS50M are two pre-set voltages enabling the power supplies to charge both 24 V and 28 V portable GPUs or operate in parallel with them. Specification includes forced ventilation with thermal protection and current overload / short circuit and reverse polarity protection.
A quick-release polarized 50 A continuously rated connector allows instant connect / disconnect of the 2 m special double insulated 16 mm section output cable fitted with Lexan Nato plug.
The design allows units to be ganged in parallel to a second power supply to double output or to operate in parallel with any START17, 29 or 58 GPU as a continuous power source or charger.
A single voltage unit (28.5 V) is also available in this range (FW28-PS30 / PS50).
