300W 3” x 5” Power Supplies for IEC/EN 60335 and IEC/EN 61558 Applications
November 19, 2019 by Paul Shepard
Delta Electronics has introduced the new PJH series of open frame ac-dc power supplies with 300W output power. The PJH-24V300WBCA and PJH-36V300WBCA provide up to 240W power convection cooled without additional metal plate. With external fan cooling, they 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 3” x 5” convection cooled design, suitable for limited space in household applications. PJH series is certified to IEC/EN/UL 62368-1 and comply to OVC III for harsh industrial and farming applications.
