Product description
  • DDRH-120 series is a 250 - 1500Vdc high reliable ultra-high input DIN railtype DC-DC converter which can supply stable working voltage for the load. It is suitable to be mounted on TS-35/7.5or 15 rails. Main features are as following: easy to install DIN rail type, narrow width(63mm) in slim design, -40-+80°C wide range operating temperature, 4KVac high isolation voltage, operation at 5000m altitude, high efficiency, low ripple & noise, complete protections and so on. DDRH-120 is compliant with BS EN/EN61000-6-2 standard regarding immunity for industrial environments. It is suitable for industrial automation, surveillance, telecommunication and 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.
