DIN-rail switching supply converts 85 to 264V AC to 24 to 28V DC at 3.8 A with 50 mV noise and 25 ms hold-up

  • Wide input range accepts 85 to 264V AC for flexible installation
  • 100W output delivers 3.8A at 24 to 28V DC for reliable power
  • DIN rail mounting fits standard enclosures for quick panel assembly
  • Green LED status indicator shows operation at a glance
  • IP20 rated plastic case protects internals in industrial environments

Industrial DIN Rail Power Supply

The Sola/Hevi-Duty SDP424100LT is a switching DC power supply designed for DIN rail mounting in control cabinets. It accepts a wide AC input range of 85 to 132V and 176 to 264V at 60 Hz single phase. The unit delivers a regulated 24 to 28V DC output at up to 3.8 amps with a 100W power rating. A green LED provides immediate visual status confirmation.

Suited for Automation Panels

This supply fits panels requiring a plastic NEMA 1 enclosure with an IP20 rating and compact dimensions of 2.95 in height, 2.85 in width and 3.8 in depth. It serves applications tolerating output noise below 50mV and a hold-up time exceeding 25 msec. Installers needing forced-air cooling, redundant parallel operation or a higher ingress protection rating should select a different series.

100W Power Rating Decides Fit

The 100W rating determines whether this unit can drive the connected load without overload. Verify that total downstream consumption stays within this limit before specifying the SDP424100LT for the installation.

Questions about this item

How do I wire the SDP424100LT to a 176 to 264V AC or 85 to 132V AC supply and DIN rail, and what step is often missed?

Connect the AC input to the rated voltage range, secure the unit on a DIN rail, then set the output between 24 and 28V DC; the step often missed is verifying the green LED lights to confirm correct polarity and output regulation.

What maintenance or replacement will the SDP424100LT need over time?

The plastic case and internal switching components are sealed; no user-serviceable parts exist, so replacement of the entire unit is required if the green LED fails or output noise exceeds 50mV.

What limit appears first when the SDP424100LT runs continuously at full load?

The 100W power rating and 3.8A output current limit are reached first; sustained operation beyond this triggers protection and the hold-up time drops below 25 msec.
