Open frame power supply LPP300S series

AC/DCsingle-outputSMPS

Overview
The LPP300 Series is a compact open-frame AC-DC power supply delivering up to 300 W (with airflow) in a low-profile 0.75 in form factor. Available nominal outputs are 12 V, 24 V and 48 V. Units meet Class B EMI (4th Edition) and provide Type BF medical leakage performance, making them suitable for medical and industrial equipment such as patient monitors, infusion pumps and test & measurement systems. Integrated protections include output overvoltage, short-circuit and overload protection.
