General Description
The PJB series of Open Frame Power Supply comes with universal AC input at 85Vac to 264Vac. Features are including low leakage /
Inrush current and conformal coating on the PCBAs to provide protection against dust and chemical pollutants and low power
consumption for optional. The built-in active PFC provides PF > 0.97 and fulfills Harmonic Current Emission according to IEC/EN 61000-
3-2. The feature built-in Power Boost of 200% for 10 seconds enables reserve power to be always available for reliable startup of loads
with high inrush current, thus eliminating the need of a more expensive power supply unit at higher power rating. Metal chassis and case
cover are available as options for different installation preferences.
