Loads with Reverse Current
The dummy resistor will shunt the reverse current and prevent the output voltage from rising.
Reverse-Current Absorption by Dummy Resistor
Also, for pulse reverse current, the average current value when the flow is in the supply direction,
can be stabilized by connecting capacitor (1000MF~10000μF) in parallel.
For Pulse Reverse Current
Please do not apply voltages to the output terminal which exceed the power supply’s rated output
voltage.
Please use specialized break units etc. to suppress the generation of over voltage when there is
regenerative reverse current in the motor inverter load.

Caution
The ZX-S Series power supply does not possess any function which will stabilize the output voltage
against the reverse current generated from the load. If the maximum sink current (0.4A) is
exceeded, the output voltage will rise above the rated value and burn-out the internal circuits.
Please do not apply voltages to the output terminal which exceed the power supply’s rating.
