TDK-Lambda ZPD40-512 Power Supply

TDK-Lambda ZPD40-512 is a 40 W open-frame AC-DC power converter that delivers +5 V at up to 3.2 A and +12 V at up to 2 A from a universal single‑phase input of 90–264 VAC or 120–370 VDC. Built as an open-frame PCB module, it is designed for mounting inside equipment to supply dual rails for digital logic, peripherals, instrumentation, or embedded control systems, all from a compact 40 W footprint. The unit achieves roughly 77% typical efficiency under nominal load, enabling modest heat generation for a given output, and its dual-output topology simplifies power distribution by consolidating logic and high‑current needs into a single module. ZPD40-512 is a legacy device in the ZP/ZPT family and has been discontinued, with last shipments recorded on April 30, 2022, so current procurement relies on legacy stock or substitution with contemporary ZPD/ZPT low‑profile offerings.
