HXFrequently Asked Questions
What is the input voltage range for the NDR-120 series power supply?
The universal AC input voltage range is 90-264VAC, and it also supports DC input from 127-370VDC by connecting AC/L (+) and AC/N (-).
What protections are built into the NDR-120 DIN rail power supply?
It features short circuit, overload, over voltage, and over temperature protection to ensure safe operation. The overload protection uses a constant current mode.
Can the NDR-120 be mounted on standard DIN rails?
Yes, it is designed for easy installation on standard TS-35/7.5 or TS-35/15 DIN rails.
What are the output voltage options available for this series?
The NDR-120 series offers three output models: NDR-120-12 (12V, 10A), NDR-120-24 (24V, 5A), and NDR-120-48 (48V, 2.5A).
What is the recommended installation distance for optimal cooling?
For permanent full power load, it is recommended to keep a distance of 40mm at the top, 20mm at the bottom, and 5mm on both sides. If the adjacent device is a heat source, the recommended spatial distance is 15mm.
What is the warranty period for the NDR-120 series?
The NDR-120 series DIN rail power supplies come with a comprehensive 3-year warranty.
