Frequently Asked Questions

Can I use the NDR-120-12 for 12V PLC I/O modules and relays in a control panel?

Yes, this model is a 12V DIN rail power supply rated for 120W and 10A, which aligns with 12V control-panel loads. Its slim 40.0 mm profile and DIN rail form factor also make it practical for industrial automation cabinets where space is limited.

Is the NDR-120-12 a good fit for 12V building management or panel-based control systems?

It can be used where the control system requires a 12V DC supply and the total load stays within 120W or 10A. The 90-264VAC input range also suits sites that need one DIN rail supply for a wide AC input range inside a control enclosure.

Can this power supply be used for 12V industrial automation accessories inside a DIN rail cabinet?

Yes, it is intended for DIN rail mounting and is suited to protected cabinet applications that use 12V DC. The metal case, slim size, and EMC EN55022 class B feature make it relevant for enclosed automation panels where orderly DIN rail layout matters.

How does the NDR-120-12 compare with other Mean Well NDR DIN rail models?

Within the listed siblings, the NDR-120-12 is 120W, 12V, 10A. Other options are NDR-120-24 at 120W, 24V, 5A; NDR-120-48 at 120W, 48V, 2.5A; NDR-240-24 at 240W, 24V, 10A; NDR-240-48 at 240W, 48V, 5A; NDR-480-24 at 480W, 24V, 20A; NDR-480-48 at 480W, 48V, 10A; NDR-75-12 at 75.6W, 12V, 6.3A; NDR-75-24 at 76.8W, 24V, 3.2A; and NDR-75-48 at 76.8W, 48V, 1.6A.

Can the NDR-120-12 be used in hot or cold control cabinet environments?

The specified operating temperature range is -20°C to +70°C, so it covers a broad range of indoor cabinet conditions. No IP rating is provided in the listed specs, so it is best suited to protected control cabinets or enclosures rather than exposed outdoor or washdown areas.
