A DIN-rail power supply is defined by where it mounts and what it feeds. It clips onto the 35mm rail that runs the length of an industrial control cabinet, takes line-voltage AC in and hands regulated DC — most often 24 VDC — to the PLC, the industrial switch, the sensors and the field devices sharing that rail. Choosing one well is mostly a matter of matching three things to the panel: the output voltage the load bank runs on, the continuous wattage the load actually draws with headroom left over, and the width the unit takes on a rail that is usually already crowded. Every unit on this page names DIN-rail mounting in the manufacturer's own title, which is the fact a panel builder is checking first.

Output voltage is the decision that cannot be wrong. Industrial controls standardise on 24 VDC far more often than anything else, but 12 VDC and 48 VDC panels exist and the units here are titled per voltage — a 48 VDC supply on a 24 VDC bus is a design error you find at commissioning, not a preference. Wattage is the decision people cut too fine: a supply sized exactly to the calculated draw runs hot and has no margin for the inrush of a contactor or the day a device is added, so the reliable rule is to size the continuous load and then step up, not to buy to the number on the schedule.

The third decision is the rail itself. A control cabinet's rail is a fixed length shared by breakers, terminal blocks, relays and the supply, and a wide brick that fits on the bench may not fit beside the parts it powers — the compact and slim units here exist precisely for that constraint. Cards carry live pricing and current availability from the catalog; send the panel's DC load list and we will size the supply, the rail space and the upstream protection together.

Buyer's checklist

How to choose a DIN-rail power supply

  • Fix the output voltage to the bus, not the vendor. Industrial controls are usually 24 VDC, but 12 and 48 VDC panels exist and these units are titled per voltage. A supply on the wrong bus is a commissioning failure, so read the output voltage on the row before anything else.
  • Size the continuous load, then step up. Add the steady draw of every device on the rail, leave headroom for inrush and for the device someone adds next year, and buy the next wattage up. A supply run at its rated ceiling runs hot, and heat is what shortens a supply in a sealed cabinet.
  • Measure the rail space you actually have. A control cabinet's 35mm rail is shared with breakers, terminals and relays; the compact and slim units here exist for crowded panels, and the width on the datasheet is the number that decides whether the build fits.
  • Check the input range against the site. These units are titled with their AC (and often DC) input ranges — 120/230 VAC is common, several accept wide AC/DC input. Match it to the panel's supply and to any generator or DC backup feeding it.
  • Read the efficiency and the thermal envelope. The titles here state efficiency figures; in a sealed enclosure the waste heat has nowhere to go, so a more efficient supply is also a cooler cabinet, and the ambient rating is what governs derating.
  • Plan for redundancy where the process cannot stop. A second supply, a redundancy module or an upstream UPS belongs in the design where a dropped 24V rail stops a line — decide it at the panel stage, not after the first nuisance trip.
  • Order the supply with what protects and mounts it. The upstream breaker, the DIN terminals, the rail itself and the enclosure land on the same panel; quoting them together is what avoids a second delivery in the middle of a build.

Voltage and wattage: the two numbers that decide the row

Almost every DIN-rail supply on this page is a single-output AC-to-DC unit, and the two numbers that separate them are output voltage and continuous wattage. Voltage is the hard constraint: the field devices, the PLC and the industrial switch on the rail all expect one DC bus, and 24 VDC is the overwhelming default in industrial controls, with 12 VDC and 48 VDC panels the exceptions the titles here call out. Get it right once, at the design stage, and it never has to be revisited.

Wattage is where judgement comes in. The honest figure is the sum of the continuous draw of everything on the rail, plus margin for the inrush a contactor or a motor starter pulls at switch-on and for the growth every panel eventually sees. The units here run from around 18W up to 240W, and the reliable practice is to size the load and then step up a band rather than buy to the calculated number — a supply run at its ceiling in a sealed cabinet runs hot, and heat is the thing that ages it.

Where these live and what ships around them

A DIN-rail supply is rarely bought on its own. It is one clip on a rail that also carries the branch breaker that protects it, the terminal blocks that distribute the DC bus, and the PLC, relays and industrial switch it feeds — and the whole assembly lives in an enclosure rated for the environment, whether that is a clean control room or a washdown line. The compact and slim units here exist because that rail is finite: a build that is correct electrically still fails if the supply is wider than the gap left for it.

Uniqcli quotes the supply alongside the rest of the panel and the enclosure, and alongside the industrial switching, media converters and field devices it powers, so an industrial-automation or edge-networking build lands as one accountable order rather than several. Send the DC load list, the bus voltage, the input available at the site and the rail space, and we will come back with sized part numbers, availability, lead times and volume pricing, with the protection and mounting hardware alongside.

FAQ

Common questions

What voltage DIN-rail supply do I need?
The one your control bus runs on, which in industrial controls is 24 VDC far more often than anything else — but 12 VDC and 48 VDC panels exist and the units on this page are titled per output voltage. The load decides it: the PLC, the industrial switch, the sensors and the field devices on the rail all expect one DC bus, so read the output voltage on the row and match it to the bus rather than to a preference. A supply on the wrong voltage is a design error you discover at commissioning.
How much wattage should I size for?
Add the continuous draw of everything on the rail, then step up a band rather than buying to the exact number. Leave headroom for the inrush a contactor or motor starter pulls at switch-on and for the devices a panel accumulates over its life. The units here run from roughly 18W to 240W; a supply sized exactly to the calculated load runs at its ceiling, and a supply run at its ceiling in a sealed cabinet runs hot, which is what shortens its life.
Will a DIN-rail supply fit any control cabinet?
It clips onto the standard 35mm DIN rail every industrial cabinet uses, so the mounting is universal — but the width is not. That rail is shared with breakers, terminal blocks and relays, and a wide supply that fits on the bench may not fit beside the parts it powers. The compact and slim units here are titled as such for exactly that reason; check the unit's width against the free rail space in the panel before you order.
Are these units suitable for wet or washdown environments?
The supply itself belongs inside a rated enclosure; it is the enclosure, not the supply, that carries the environmental rating for a washdown or outdoor location. Read each unit's stated operating temperature range and mount it in a cabinet rated for the site. Where the environment is harsh, plan the enclosure and its rating at the same time as the supply — the two decisions are one, and we can quote the enclosure alongside the panel.
Can business, government and education buyers order these?
