Description The Ekinex® EK-PSUD24 is a compact DIN-rail switching power supply with universal input and an adjustable output voltage. It accepts 100–240 Vac (50/60 Hz) or 110–350 Vdc and provides an adjustable output from 23.3 to 28 Vdc. Housed in a flame-retardant UL94V-0 plastic casing sized for 2 modular units, it integrates thermal, overload and short-circuit protections for reliable use in electrical control panels.
