The OBL04010A from Cosel is an Isolated Multiple Output AC-DC Converter that steps down an AC input voltage of 110 – 230 V to a DC output voltage of 3.3 V. It delivers an output power of 72 W and has an efficiency of 65%. This converter operates over a temperature range from 0°C to +70°C. It has undergone multiple safety testing procedures, such as radiated immunity, conducted immunity, magnetic field immunity, surge immunity, and voltage dips, thereby ensuring safety and reliability during operation.

This RoHS-compliant converter is equipped with input surge current protection, over-current protection (OCP), and over-voltage protection (OVP) to prevent over-load-related damages. It is available in a chassis-mount package that measures 116 x 60.5 x 190.5 mm and is ideal for medical and SMPS applications.
