GE Embedded Power – Power Conversion Solutions
The CLP power supply offers a great solution for OEMs requiring design flexibility of power supplies used in their applications. The module offers greater than 90% peak efficiency enabling economical and long life performance. – 90 – 264Vac input; 12Vdc output; 200W Output Power
In a small 2 x 4 inch footprint, the 12Vdc single-output CLP0212 open frame power supply delivers 80 PLUS Gold energy efficiency. With its small size, the CLP series is specifically designed to handle power challenges associated with tight space and low airflow. The CLP series utilizes a unique design approach at this power level, leveraging zero voltage switching techniques in conjunction with quasi-resonant power factor correction (PFC) circuits. Protection features include overcurrent (OCP), overvoltage (OVP), and overtemperature (OTP).

History – ;
I first noticed quasi-resonant SMPS in a Tek Logic Analyzer when i worked there. It was Cherokee, This post was made when i came online with Cherokee and Lineage and now it is GE.
2012 – Noticed today that Lineage Power is part of GE from the time this post was last edited. (See first post below.)
