MEAN WELL DDRH-120 & DDRH-240 DIN-Rail DC-DC Converters

MEAN WELL DDRH-120 and DDRH-240 DIN-Rail DC-DC Converters feature a 250VDC to 1500VDC ultra-wide input range, a high 4kVAC isolation level, and a fanless design that operates in a -40°C to +80°C temperature range. These 120W/240W units offer superior EMC performance, high altitude 5000M operation, and compliance to the IEC/EN 62109-1 PV safety standard. Both series come with complete protection, including undervoltage and reverse polarity (no damage) for the DC input as well as short circuit, overload, overvoltage, and overtemperature for the output. MEAN WELL DDRH-120 and DDRH-240 DIN-Rail DC-DC Converters can be installed on a TS-35/7.5 or 15 DIN rail and come with a three-year warranty. These DC-DC converters are suitable for photovoltaic power generation, energy storage, charging stations, industrial control systems, and other applications with high- and low-voltage DC conversion requirements.
