Model 3328QC-50 amp

PATENTED 

The 3328QC-50 is a full 28.5 Volt starting unit that will give faster, cooler starts on all turbine engines.  When plugged into 110 VAC or 220VAC, the 50 Amp power supply is large enough to power various systems such as inverters, avionics and GPS.  Always recharge immediately after use (until the green charger light appears) in order to achieve maximum battery life.

The Model 3328QC-50 amp GPU is a combination power supply (for avionics) and battery bank (for engine starting).

To recharge the unit, simply plug it into an AC wall power outlet and leave it plugged in when not in use.  The high tech proprietary chargers will maintain 100% battery charge without over charging the batteries but avoid fully discharging the batteries as damage to the cells may result.  Built with the only cost effective, patented Quick Change design in the world, the batteries in this unit can be changed easily in a matter of seconds without tools, training or downtime.

The environmentally responsible, low VOC powder coating protects the case from wear, tear and poor weather conditions.  Additionally, an all-weather cover accessory is also available to protect it further from inclement weather maximising performance and product life.

Batteries

  • Sealed cells – non-hazardous
  • Valve regulated high amperage output lead acid
  • Patented Quick Change design for 10 second battery changes

Power supply/charger

  • No duty cycle, clean continuous power
  • Over-voltage & over-current protection
  • Reverse polarity protection

NOTE When using more than 50 continuous amps, the batteries will make up the difference until they become depleted.  On most aircraft, a low voltage relay will drop the GPU offline when the voltage drops below a preset level.  Unfortunately, the GPU’s voltage will then rise back up, causing the aircraft to make use of it once more.  This, in turn, will cause it to re-drop below its preset level, creating a vicious circle.  It is this oscillation that can cause damage to aircraft components.
