Dayton 33NT11 24V 80W 3.3A DIN Rail Line Protection

SKU CH-Q0AA-78ER5

DIN-rail switching supply delivers 24 V DC at 3.3 A from 90–264 V AC input with IP20 metal case

  • Reliable 24 V DC output backed by 80 W rating
  • Wide 90–264 V AC input suits global mains supplies
  • Compact DIN-rail metal case fits tight panels
  • Green DC OK indicator gives instant status confirmation
  • Low output noise ≤ 1 % protects sensitive loads

Power Supply Overview

The Dayton 33NT11 is a DIN-rail mounted DC power supply that converts 90 to 264V AC input into a regulated 24V DC output rated at 80W and 3.3A. It uses a switching design housed in a metal case measuring 4.88 in high, 1.26 in wide and 4.02 in deep with an IP20 rating. A green DC OK indicator shows operational status and the unit operates across 47 to 63 Hz single-phase supplies.

Suitability Notes

This unit suits control panels and automation cabinets that require a compact 24V DC source with DIN-rail mounting and a metal enclosure. It is not intended for applications needing higher output current, different output voltages or redundant power configurations. Buyers who need more than 3.3A continuous output, battery-backup integration or wider temperature specifications should consider other models.

Deciding Specification

The continuous output current of 3.3A at 24V DC determines whether this supply can power the intended load; peak current reaches 4.95A for short durations. Verify that the total connected device draw stays within the 80W rating and that the 20 ms minimum hold-up time meets the ride-through requirements of the controlled equipment.

Questions about this item

How do I confirm the 24V DC output is within spec after wiring the unit?

Check the green DC OK indicator on the front; it lights when the output is present and stable.

What comes in the box and what must I source separately?

The power supply itself is included; you will need to provide DIN rail, input and output wiring, and any upstream fusing.

Which capacity should I choose for a 24V 80W load?

This model delivers 24V at 3.3A continuous (80W) with a 4.95A peak, matching that load exactly.
