Industrial DIN-rail power supply

The myVolts MDR-40-12 is a 40W single-output switching supply that delivers 12V at 3.33A from a 100-240VAC input. It mounts on ultra-thin TS35/7.5 or 15 DIN rails and is housed in ABS material for impact and scratch resistance. The unit suits control panels, automation cabinets and similar industrial installations.

Replaces bulkier linear units

This supply upgrades from larger linear transformers where cabinet space is limited and universal AC input is required. The jump is worth it when a compact, protected DC source must fit on a standard 35mm rail without forced-air cooling.

40W continuous headroom

The 12V 3.33A output comfortably runs PLCs, sensors, relays and small HMIs within its rated 40W. It runs out when the load approaches the 3.33A limit or when inrush currents exceed the built-in overload protection threshold.

商品問答

Will the MDR-40-12 clip onto a TS35 DIN rail with a 7.5 mm or 15 mm profile?

Yes, the unit is designed for ultra-thin industrial-grade DIN rail TS35/7.5 or 15 and snaps on without tools.

What is the correct wiring sequence when connecting the 100-240 VAC input to the MDR-40-12?

Connect live, neutral and earth to the marked input terminals before switching on; reversing live and neutral is the most common error.

How often should the internal cooling airflow around the ABS housing be checked on the MDR-40-12?

Inspect the ventilation gaps every six months and clear any dust build-up to maintain the overheat protection margin.
