Delta PJH series open frame power supplies

The Delta PJH series is an open frame power supply with 300W output power. The PJH-24V300WBCAA and PJH-36V300WBCA provide up to 240W of convection cooled power without an additional metal plate. With external fan cooling, it can provide 300W output power across a wide operating temperature range from -25°C to +70°C. The design is one of the few to meet both IEC 60335 and IEC 61558 in a compact 240W 76.2mm x 127mm convection cooled design, suitable for limited space in household applications. The PJH series is certified to IEC/EN/UL 62368-1 and complies to OVC III for harsh industrial and farming applications.
