Sola SDP4-24-100RT Power Supply

SolaHD SDP4-24-100RT is a 100 W DIN-rail power supply that provides a fixed 24 V DC output at up to 4.2 A, making it suitable for industrial controls, PLCs, sensors, and automation equipment in control panels. It is housed in a DIN-rail plastic enclosure for easy mounting in electrical cabinets and supports 115/230 V AC input, designed for robust use in harsh environments common in industrial settings. The unit features an initial output around 24.5 V with ±1% regulation, ripple and noise under 50 mV peak-to-peak, and a hold-up time greater than 25 ms at full load (25°C), ensuring stable operation during brief interruptions. It offers over-voltage protection below 33 V DC and is classified as NEC Class 1 for safety. The SDP4-24-100RT is part of SolaHD's SDP low-power family, and its 100 W rating, compact footprint, and DIN-rail mounting make it well-suited for machine control panels, building automation, instrumentation, and other applications requiring a reliable 24 V DC supply with solid transient performance.
