Delta's PJB open frame power supply series is designed for applications demanding low leakage current, low inrush current, high power factor value, and high efficiency. The PJB series comes with universal AC input voltage range at 85 V_AC to 264 V_AC and bears superior features like built-in Power Boost of 200% for 10 seconds which will enable reserved power to be always available during startup of loads with high inrush current, thus eliminating the need for a more expensive power supply with higher power rating while saving more space for installation. Like its predecessor, the PJ series, the PJB series has conformal coating applied on the PCBAs to protect against common dust and chemical pollutants. This enables the products to be used in harsh industrial environments and only recognized Japanese capacitors are used. Metal chassis and case covers are available as options for different installation preferences. The PJB series is certified for EMI standards according to EN 55022 and EMS according to EN 55024. The products also conform to major international safety standards according to IEC/EN/UL 60950-1 standards.
