FAQ

What is the main difference between the DR-120-24 and its replacement, the NDR-120-24?

The newer NDR series generally offers higher efficiency, a slimmer profile for space saving on the DIN rail, and a wider operating temperature range compared to the older DR series.

Is the output voltage on the DR-120-24 adjustable?

Yes, there is typically a small potentiometer located near the output terminals that allows for fine adjustment of the output voltage, usually within a range of 24V to 28V.

Can this power supply be operated in parallel to increase current?

No, the DR-120-24 datasheet does not officially support parallel operation for current sharing. For applications requiring more than 5A, a single power supply with a higher current rating should be used.
