Sola Hevi Duty SDP 4-24-100RT DC Power Supply

The SolaHD SDP4-24-100RT is a 100 W DIN-rail DC power supply that delivers a fixed 24-28 VDC output at up to 4.2 A, making it ideal for powering PLCs, sensors, relays, and other control electronics in industrial panels. It accepts universal AC input from 85–264 VAC (two ranges: 85–132 VAC and 176–264 VAC) at 47–63 Hz and provides a single 24–28 VDC output capable of 4.2 A. PowerBoost overload circuitry helps start inductive loads such as motors, relays, solenoids, and DC-DC converters without nuisance shutdowns. The unit mounts on standard DIN rails and is RoHS compliant. Some sources note that this RT variant is listed as an exception to NEC Class 2 compliance under NFPA 70 Article 725-41(a)(2). Common applications include powering PLCs, sensors, and actuators in automation and machine-control environments that require a compact, reliable 24 VDC supply.
