MEAN WELL MDR-100-12 Τροφοδοτικό ράγας DIN 100W 12V 7,5A

The MDR-100-12 stands out among compact DIN rail power supplies by delivering a full 90W from a housing barely wider than a smartphone, without forced-air cooling. Its slim 55mm profile and plastic enclosure keep control cabinets tidy, while the universal AC input and wide DC range make it equally at home on factory floors or in building automation. Unlike open-frame supplies that demand extra guarding, this unit ships ready to clip onto a TS-35 rail and power 12V loads immediately.

Highlights

• 90W continuous output at 12V DC, 7.5A
• Ultra-slim 55mm width saves DIN rail space
• Universal input: 85–264V AC or 120–370V DC
• Free air convection cooling – no fan noise or maintenance
• Full protection: short circuit, overload, over voltage, over temperature
• Green LED confirms output status at a glance

In daily use

Installation takes seconds: snap the unit onto a TS-35/7.5 or TS-35/15 rail, wire the input and output terminals, and the green LED lights up when power is good. The adjustable output (10.8–13.8V) lets you compensate for voltage drop on longer cable runs. With 3kV AC isolation between input and output, the MDR-100-12 safely separates sensitive 12V circuits from mains disturbances. The plastic housing is non-conductive, so no extra insulation is needed even in crowded enclosures.
