Powervamp’s PS30C and PS50C miniature power supplies are lightweight combination charger/power supplies able to deliver 30 or 50 amps depending on model, at a pre-set voltage between 28.4 and 31.5 volts (for 28 volt Coolspool charging) as selected by the operator. Power supplies can be connected directly to the aircraft’s external ground power
receptacle or to any of Powervamp’s portable battery GPUs. They are designed for operators of smaller helicopters andVLJs needing to download data or programme avionics in any location where size and weight are important.
The automatic 120/240 volt 50/60Hz input allows international use.A solid state voltmeter displays the output voltage selected by the mode switch.Coloured LEDs confirm mode selection. A green and red LED indicates amperage below or above current limit protection.
Unique to the PS30C / PS50C are two pre-set voltages enabling the power supplies to charge both 24 and 28 volt portable GPUs or operate in parallel with them. Specification includes forced ventilated with thermal protection and current overload/short circuit and reverse polarity protection. A single voltage unit (28.5V) is also available in this range (PS30/PS50).
