This START PAC® is the smallest 24V power supply on the market. Designed to power up 24 Volt aircraft systems, the voltage output is set to 28.5 Volts to simulate the same voltage as when the aircraft is running under power. The maximum amperage output is 25 amps. When you’re using this mini power supply, the aircraft’s electrical system can be powered up for GPS programming and light duty maintenance, bypassing the aircraft battery and thus preserving it from unnecessary wear. This means that the on-board aircraft battery is conserved for starting only. The environmentally responsible, low VOC powder coating protects the unit from wear, tear and poor weather conditions.
