General Description
The PJB series of Open Frame Power Supply comes with universal AC input at 85Vac to 264Vac. Other features include low leakage /
Inrush current and conformal coating on the PCBAs to provide protection against dust and chemical pollutants. 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.
The PJB series is certified for EMI standards according to EN 55032 and EMS according to EN 55024. The products conform to major
international safety standards according to EN/UL 60950-1 standards and are fully compliant with RoHS Directive 2011/65/EU for
environmental protection.
