The PWB-5002 from Astrodyne TDI is an Isolated AC-DC Converter that steps down an AC input voltage from 90 - 264 V to a DC output voltage of 12 V. It delivers an output power of 5 W and has efficiency from 71 - 80%. This converter integrates over-voltage protection (OVP), short-circuit protection, and over-current protection (OCP) circuitries to prevent over-load-related damages. It is designed to cool the system based on a convection mechanism. This converter is available in a through-hole package that measures 1 x 2 x 0.6 inches.
