Special Loads
This section explains about loads with reverse current and pulse current loads as special loads.
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, when the pulse reverse current flows and the average current value is in the supply direction, the voltage can be
stabilized by connecting capacitor (1000μF to 10000μF) in parallel.

When
This machine does not have functions to stabilize the output voltage against reverse current
from loads. If the maximum sink current 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.
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.
