Industrial DIN-Rail Power Supply

The myVolts DR-120-24 is a 24V 5A 120W AC-to-DC unit built for TS-35/7.5 or 15 DIN-rail mounting. It accepts a universal 85-264 VAC input at 47-63Hz and delivers a single regulated output through screw terminals. The silver metal enclosure measures 2.58 x 3.94 x 4.93 inches and carries 3C, CE and ISO approvals for industrial environments.

Sustained Load Behaviour

Efficiency reaches 88% with load regulation of ±1% and line regulation of ±0.5%, while ripple and noise stay at 150 mV p-p. Continuous operation is rated from -30°C to 70°C, with automatic recovery after over-voltage, over-current, over-temperature or short-circuit events. The 100% full-load burn-in test confirms stable output under prolonged demand rather than brief peaks.

Installation and Common Issues

The supply clips onto standard DIN rails and uses clearly marked screw terminals for ground, live, neutral and DC output connections, with an adjustable +V ADJ potentiometer for fine voltage setting. Wiring errors such as reversing live and neutral or omitting the ground connection are the most frequent causes of start-up failure. Ensure the enclosure has adequate airflow when ambient temperatures approach the upper limit.

Questions about this item

How much heat and noise does the DR-120-24 produce when running continuously at 120W?

The unit operates from -30 to 70 °C with 88% efficiency and 150 mV ripple, so waste heat is modest and there is no fan to generate noise.

What wiring and rail hardware must I already have to install this supply?

You need a TS-35/7.5 or TS-35/15 DIN rail, plus live, neutral and ground cables for the screw terminals on the input side.

Will the 24V 5A output work safely with older 24V PLCs or relay banks that lack their own protection?

Yes — over-voltage trips at 135%, and short-circuit, overload and over-temperature protections all auto-recover, shielding legacy gear.
