Load Bank LO-28/2500
Load bank LO-28/2500 is designed to apply current loads to 28 V d.c. outputs of any electronics power supply units available on the market, including ground power units (GPU).
The device allows to:
- apply constant current loads
- apply variable current load according to a pre-set program
- measure voltage and load current with analogue indicators on the device’s control panel
- connect external control-measuring devices to the measuring sockets
The unit provides comfort and functionality for daily maintenance and servicing of the controlled power supply units. Small weight and dimensions allow for easy loading on and attachment to the service vehicle, thus significantly increasing safety during transport.

Load Bank 3x200 V 400 Hz LO -115/260 type
With Load Bank LO-115/260 current loads can be set for 3x200 V, 400 Hz output voltage of a ground power unit for aircraft ground support equipment (GSE).
Features:
- indication of the A, B and C live phases and of their rotation direction
- load current setting by operator
- testing ground power units by variable load current’s automatic setting according to a pre-defined programme
- exhaust systems’ decarbonisation of GPU’s Diesel engine by variable load current’s automatic setting
- according to a pre-defined programme
- three-phase voltage, frequency, and current measurements with analogue indicators on the control panel
- control and indication of EF protection system’s performance
- connections to external control and measurement devices’ measuring sockets
The Load Bank provides comfort and functionality for everyday and scheduled maintenance of the power units. Its small weight and size allow easy loading and fixing in the service vehicle’s luggage compartment, significantly increasing the safety during transport.
