RSDH-150/300 Series:150W & 300W Ultra-Wide 250~1500Vdc Input Enclosed Type DC-DC Converter

By: Frank Chen / Product Manager

In recent years, the intensifying climate changes drove countries around the world to commit to the goal of Net Zero Emissions. Combined with increasing cost and shortage of natural resources, the demand for renewable energy such as photovoltaics and energy storage has increased drastically. In our effort to contribute to the growing demand, MEAN WELL is releasing the new 150W/300W ultra-wide 250~1500Vdc input enclosed type DC-DC converters – RSDH-150/300 series.
RSDH-150/300 series’key features include: 250~1500Vdc ultra-wide input range, fanless design operational in -40~+80oC wide temperature range, 4KVac high isolation level, input/output complete protection features, superior EMC performance, high altitude 5000M operation, and compliance to the IEC/EN62109-1 PV safety. These features enable the RSDH-150/300 series to be suitable for PV, energy storage, charging station, and other applications that have high voltage to low voltage DC conversion requirement.
