Dayton

Dayton 33NT19 24V DC 30W 1.25A DIN Rail line protection

SKU CH-7F51-7HBJK

A DIN-rail switching power supply delivering 24 V DC at 1.25 A from a 90–264 V AC input

  • Wide 90 to 264V AC input suits global mains
  • 24V DC at 1.25A delivers 30W for control circuits
  • DIN rail mount fits standard enclosures in 0.9in width
  • Green DC OK indicator confirms output at a glance
  • Low 1% output noise protects sensitive loads

DIN-rail 24 V DC supply for control panels

The Dayton 33NT19 is a switching power supply that mounts on a standard DIN rail and delivers 24 V DC at up to 1.25 A. It accepts a wide 90 to 264 V AC input at 47 to 63 Hz, making it suitable for industrial control cabinets and automation equipment.

Green DC OK indicator and IP20 enclosure

A front-panel green LED shows when the output is within specification, giving immediate visual confirmation without a meter. The plastic case carries an IP20 rating and NEMA 1 protection, so it is intended for indoor enclosures rather than exposed or wash-down environments.

30 W continuous with 16 ms hold-up time

At the full 30 W rating the unit supplies 1.25 A continuously and maintains output for more than 16 ms after mains loss, allowing orderly shutdown of PLCs or sensors. Loads requiring more than 30 W or peak currents above 1.25 A will need a higher-capacity supply.

Questions about this item

How often should the internal electrolytic capacitors in this 30 W DIN-rail supply be inspected or replaced under continuous duty?

The unit specifies a hold-up time greater than 16 ms, which reflects capacitor health; plan inspection at the manufacturer’s recommended interval, typically every 3–5 years at full 1.25 A load.

Which parameter reaches its limit first when the supply runs continuously at 1.25 A output?

The 30 W power rating and 1.25 A peak current are the hard limits; sustained operation at full load leaves no headroom before the over-current protection engages.

What is the typical heat rise and audible noise when this IP20 plastic-cased supply operates all day at 24 V DC output?

With output noise ≤ 1 % and no fan, the supply relies on convection through the 3.54 × 0.9 × 4.02 in case; expect warm but touch-safe surfaces and silent operation at full load.
