Introduction
Building on the success of MEAN WELL’s 60-300W DDRH-60/120/240 and RSDH-150/300 series, we are now introducing the DDRH-15/30/45 series. This new addition offers small wattage ultra-wide input DC-DC converters with a high voltage range of 150~1500 Vdc, designed for applications requiring compact and reliable power solutions.
Key Features
The DDRH-15/30/45 series is versatile, with multiple installation options (PCB mounting, screw terminal, or DIN rail) to suit various project needs. The ultra-wide input voltage of 150-1500Vdc, paired with its high temperature tolerance(-40+80°C) makes this series ideal for use in demanding environments. Its 4K Vac high isolation between input and output ensures safety, especially for systems deployed at high altitudes of up to 5,000 meters.
The series has been certified with the IEC62109-1 photovoltaic standard, allowing it to be widely used in applications such as photovoltaic systems, energy storage solutions, charging stations, and other HV-LV conversion setups.
