描述

SPD482401B is a 240W switching power supply designed for DIN rail installation in industrial automation applications. It features universal AC input (115–230 VAC full range), selectable output voltage of +24 VDC at 10 A or +48 VDC at 5 A, and includes power factor correction (PFC) as standard with high efficiency (87–90% typical). The unit incorporates comprehensive protections including short-circuit protection with fold-forward characteristic, overvoltage protection (125–140%), and internal surge protection via varistor, along with LED indicators for DC power ON and DC low conditions. With compact dimensions (124.5 × 83.5 × 123.6 mm for screw terminal type), parallel connection capability, and approvals including UL/cUL, TUV/CE, and ISA 12.12.01 Class 1 Division 2, this supply is ideal for demanding industrial control systems requiring reliable, space-efficient power delivery.
