Delta Electronics introduces the new PJH series of open-frame power supplies with 300W output power. PJH-24V300WBCA and PJH-36V300WBCA provide up to 240W, convection-cooled 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 3” x 5” 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.
Other features include built-in active PFC, remote on/off, remote sense, power good signal; Class I or Class II (double isolation) configuration with universal AC input voltage range; high efficiency of up to 94%; extreme low temperature cold-start at -40°C; and approval for Pollution Degree 3, among others.
