In recent years, the demand for renewable energy such as photovoltaics and energy storage has increased drastically. As a response, MEAN WELL launched the DDRH-60 and RSDH-150/300 (details in table below) subsequently. Now we are launching a new 120W/240W ultra-wide 250~1500Vdc high voltage input DIN rail DC-DC converter, the DDRH-120/240 series.
 
DDRH-120/240 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 DDRH-120/240 series to be suitable for PV, energy storage, charging station, and other applications that have high voltage to low voltage DC conversion requirement.
