Power Supplies

Power supplies are switch-mode (SMPS) units that convert AC mains voltage into the regulated DC voltage on which PLCs, sensors, relays, HMIs and similar devices operate. They are used in machine and control panels to produce the 24 V DC control voltage, and also to supply electronic boards and LED lighting that run on 5 V, 12 V and 48 V DC. The category is divided into three groups by mounting style: DIN rail power supplies that clip onto a DIN rail, perforated type power supplies in metal housings screwed to the mounting surface, and power supplies with terminal connectors; Schneider Electric Modicon series power supplies and a redundancy module are also listed here. Isıso, Delta Electronics, Schneider Electric and ABB models are available in outputs such as 60 W, 120 W, 240 W and 480 W. Select the output voltage according to the devices to be supplied, the rated current according to the total load current and the inrush current of the loads, the mounting type according to the space in the panel, and the input voltage range according to the mains. The current a power supply can deliver may decrease at high ambient temperature; if the inside of the panel is hot, check the manufacturer's temperature-load derating curve.

How to choose Power Supplies

Power supplies are switch-mode (SMPS) units that convert AC mains voltage into the regulated DC voltage on which PLCs, sensors, relays, HMIs and similar devices operate. They are used in machine and control panels to produce the 24 V DC control voltage, and also to supply electronic boards and LED lighting that run on 5 V, 12 V and 48 V DC.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
