Industrial DIN-Rail Power Supply

The myVolts NDR-75-12 is a switching power supply built for industrial PLC electric cabinet drives. It accepts a universal AC input from 100 to 240 VAC and delivers a stable 12 V DC output at 6.3 A. An aluminum alloy chassis provides durability and meets safety certifications including UL508 and TUV EN60950-1.

Guide-Rail Mounting and Protection

The unit mounts directly onto standard TS35 DIN rails of 7.5 or 15 mm height for quick installation inside control cabinets. Input wiring uses three screw terminals while the output provides four points. Built-in protections cover short circuit, overload, overvoltage and overheating, with automatic recovery once conditions return to normal.

75 W Capacity With High Efficiency

Operating at 85.5 % efficiency, the supply handles continuous loads up to its rated output with ripple and noise kept to 100 mV. Overload protection engages at 105 to 130 % of rated power using constant current limiting. A mean time between failures of 486,200 hours indicates long service life in demanding environments.

Questions about this item

At what load does the constant-current limit engage on the NDR-75-12?

The supply switches to constant-current mode when output reaches 105 % to 130 % of rated power, then auto-recovers once the load returns to normal.

How much audible noise does the fanless aluminium chassis produce during continuous operation?

The unit has no fan; cooling is passive through the aluminium alloy case, so it adds virtually no acoustic noise in a cabinet.

Which DIN rail profiles does the TS35 mounting clip accept?

The clip fits standard TS35 rails in both 7.5 mm and 15 mm heights.
