The UH2H series provides up to 504W/42A output with industry standard half brick package. The efficient SR
stage is combined with patented “Buck Reset” topology that would reduce power loss to achieve 144W/in 3 power
density. The multi-layer single side circuit board design plus the patented Sink-Plate technology would enhance
the thermal performance and improve its reliability. Modules are designed for Telecom, Servers, Networking
equipments and other applications that use a 300V (200~400V) input bus.
