Dayton 33NT20 24V 50W 2.1A DIN Rail line protection

SKU CH-A4PA-B4P79

DIN-rail switching power supply delivers 24 V DC at 2.1 A (50 W) from a 90–264 V AC input with IP20 protection and a green DC-OK indicator

  • Wide 90-264V AC input suits global mains
  • 24V DC 50W output powers 2.1A loads reliably
  • DIN rail mount fits standard control cabinets
  • IP20 plastic case protects internals in dry areas
  • Green DC OK LED gives instant status check

24 V DC DIN-Rail Power Supply

The Dayton 33NT20 converts 90 to 264 V AC into a regulated 24 V DC output rated at 50 W and 2.1 A. It mounts on a standard DIN rail inside a plastic enclosure measuring 3.54 in high, 1.26 in wide and 4.02 in deep. A green DC OK indicator shows when the output is present.

Industrial panels needing a compact 24 V source

Control cabinets, automation racks and machine builders who need a single-phase supply with IP20 protection and less than 1 % output noise will find this unit a direct fit. Installations that require higher wattage, redundant outputs or a wider operating temperature range should look at larger chassis-mount supplies.

50 W continuous with 16 ms hold-up

The 2.1 A output comfortably runs PLCs, sensors and small actuator banks while the 16 ms hold-up time bridges brief mains interruptions. Loads that exceed 50 W or demand peak currents above 2.1 A will trip the internal protection and require a higher-rated supply.

Questions about this item

What AC input voltage range must the installation provide for the 33NT20 to operate?

The unit accepts 90 to 264 V AC at 47 to 63 Hz single-phase, so any standard mains supply within that window will power it.

Can the 33NT20 share a DIN rail with legacy 24 V DC loads that draw up to 2.1 A?

Yes, its 24 V DC, 50 W, 2.1 A output can supply existing 24 V devices as long as their combined draw stays at or below 2.1 A.

How do I confirm the 33NT20 is delivering regulated 24 V DC after wiring it?

The green DC OK indicator lights when the output is present and within specification, giving immediate visual confirmation.
