The Power Systems International Series of mobile DC ground power systems are designed for aircraft engine starting and battery charging applications for “point of use” at the aircraft parking stands, in maintenance hangars or in avionics workshops, aircraft manufacture and training simulators where a rugged heavy duty and reliable isolated DC power source is required.
This mobile power system is designed for connection to the normal 50Hz (or 60Hz) 3 phase 400V mains source and produces an output of 28V DC to provide all types of helicopters and small aircraft with a high stability power supply for charging on board batteries and can deliver a current limited short duration peak power output for engine starting.
Power Systems International offer a wide range of 28vDC units, split into three main categories:
- The DD range, designed for rugged uses, such as offshore installations (combination only)
- The PS Range suitable for hangar and outdoor use (Continuous, Starter and Combination) or
- The SP Range, which is integrated into our 400Hz product (combination only)
There is little audible noise, no vibration, toxic exhaust fumes or environmental pollution as produced by diesel driven systems or when the aircraft is running its engines or APU. This series of mobile power units is designed to deliver the aircraft engine peak starting current of up to 2,400A and will keep the battery fully charged whilst the aircraft is on the ground thus reducing battery stress and preserving the life expectancy of the expensive on board aircraft batteries.
The standard DD series 28V DC ground power unit is constructed in an all welded sturdy press formed steel enclosure, rust inhibited and painted in colours and finish to suit individual customer requirements. The converter enclosure upper section top is fitted with handling bars at each end for one person positioning, the base frame section is fitted with lockable swivelling wheels.
The PS range is smaller and lighter and designed to be positioned as close to the aircraft as possible, and the series comes with wheels and rugged handles for manual handling. The unit comes with a longer 50 or 60Hz input cable, and shorter output DC cable to reduce the considerable costs and weight of DC Cable.
Finally the SP range is designed to offer the most flexibility where the aircrafts could required 400Hz power or 28vDC. This also comes in static and mobile options.
Units can be offered with a stainless steel casing, for the harsher environments.
The units can also handle a wide range of operating environments, with temperature ranges of -20c to +60c, and come with IP ratings of up to IP54.
