Sola/Hevi-Duty SDN424100LP 115/230V AC 24V DC 92W 3.8A DIN line protection

SDN-P Series 24V DC DIN Rail Supply

The SOLAHD SDN424100LP is a switching DC power supply that accepts 115 to 230V AC or 90 to 375V DC input and delivers a regulated 24V DC output at 3.8A for a 92W power rating. It mounts on a standard DIN rail inside a metal case rated IP20 and NEMA 1, measuring 4.88 in high, 2.56 in wide and 4.55 in deep. A green DC OK status indicator provides visual confirmation of normal operation.

For Control Panels Needing Reliable 24V DC

This unit suits automation cabinets, industrial machinery and building-management systems that require a compact, single-phase supply with a wide input range and 47 to 63 Hz tolerance. It is not for applications demanding higher output current, redundant or parallel operation, or battery-backup integration, nor for environments requiring an IP rating above IP20 or a hold-up time beyond 100 msec.

Steady Output With Low Ripple Under Load

Under continuous operation the supply maintains output noise below 50 mV and sustains the full 3.8A load without derating, thanks to its metal enclosure and convection cooling. Hold-up time exceeds 100 msec, bridging brief mains interruptions so connected PLCs, sensors or actuators remain powered during short sags or switching events.
