Details
Meanwell DDRH-45-48ST is a 150~1500Vdc high reliable ultra-high input DC-DC converter with 48V0.93A12~24Vo:100mVp-p 48Vo:150mVp-p. The item could supply stable working voltage for the load. Meanwhile, the main features are as following: compact size, -40~+80℃ wide range operating temperature, 4KVac high isolation voltage, operation at 5000m altitude, low ripple & noise, complete protections and so on. Moreover, this series has DIN Rail type. It is suitable to be mounted on TS-35/7.5 or TS-35/15 rails. In addition, DDRH-45-48ST is designed to meet UL1741 (By requested) and IEC62109-1 standard. It is suitable 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.
