Lightweight 28V DC power supply, fitted with solid state voltmeter and ammeter, capable of providing 300A continuous power for avionics use.
The PS300 is a solid state hand-portable power supply delivering a maximum of 300A at a pre-set voltage of 28V DC for avionics use. The unit can be connected directly to the aircraft’s external ground power receptacle and is primarily for regional airline operators of turbine and turboprop DC aircraft or MROs requiring continuous power for maintenance. It is also used to power large DC aircraft at air shows.
The unit is compact, lightweight and able to power air conditioning on most business jets and can be placed under the fuselage or wing of small aircraft or helicopters, freeing up hangar floor space.
The PS300 is fitted with three 100A power supplies connected in parallel. Power supply healthy LEDs are fitted to the front panel for diagnostics. When pressed, the emergency stop button immediately disconnects power to the aircraft. The front-mounted quick-disconnect output connector allows leads of different configurations to be instantly connected to the unit.
Key-switch input voltage selection allows operation at either 180–264V AC three phase or 311–457V AC / 47–63Hz three phase for international use. A solid state voltmeter and ammeter displays the output voltage and current, enabling operators to monitor the current draw of avionics and other pre-flight loads. Supplied with Nato lead set, input lead and heavy-duty canvas protective jacket. .
