Dayton 33NT18 24V DC 15W DIN Rail Power Supply

DIN-Rail 24 V DC Supply

The Dayton 33NT18 is a compact DIN-rail power supply that converts 90 to 264 V AC mains into a regulated 24 V DC output rated at 15 W and 0.63 A. It suits control panels, sensor loops and small automation loads that need a low-power DC source mounted on standard rail.

Wide-Input Switching Limits

The switching design accepts a universal 90–264 V AC range at 47–63 Hz single-phase, so it works on global mains without selector switches. Hold-up time exceeds 16 msec to ride through brief dips, while output noise stays at or below 1 % and the green DC-OK indicator confirms regulation. The IP20 plastic case is rated NEMA 1 for indoor cabinet use only.

15 W Capacity Boundary

At 15 W the unit comfortably runs a few PLC I/O modules, a modest sensor string or a single small actuator. It reaches its limit when total load approaches 0.63 A; any expansion beyond that requires a higher-wattage supply. The 3.54 × 0.9 × 4.02 in footprint fits tight rail space, but the fixed 15 W ceiling means it cannot support growing loads or multiple high-draw devices.
