Details
Meanwell DDRH-120-32 is a high reliable DC-DC converter with 32V3.75A0-3.75A120W240mVp-p30-36V2000μF. The unit highlights DIN rail type, 250~1500Vdc ultra-high input, and supplies stable working voltage for the load. At the same time, it is suitable to be mounted on TS-35/7.5 or 15 rails. The main merits are as following: easy to install DIN rail type, narrow width (63mm) in slim design, -40~+80℃ wide range operating temperature, 4KVac high isolation voltage, operation at 5000m altitude, high efficiency, low ripple & noise, complete protections and so on. Apart from them, DDRH-120-32 is compliant with BS EN/EN61000-6-2 standard regarding immunity for industrial environments. The item is ideal for industrial automation, surveillance, telecommunication, and therefore can be widely deployed in the applications of new energy generation such as solar power, and windmill power generation, for instances, photovoltaic power systems, high voltage inverting, DC bus centralized application, ESS, charging pile, railway and so forth.
