The HV electronic loads are used to test the EPC (Power supplies embedded in satellite).
Each drawer represents a HV electronic load which can withstand a high voltage (up to 30kV). The operator can define the current’s setting that the dynamic load could sink. Each electronic load works as a variable resistor : the value of this resistor is adjusted according to the current’s setting.
A different waveform can be be applied as the current setting (square, sinus,…).
The device can be operated locally using front panel controls or remotly through a 25-pin remote control interface.
