Converter 100W 250~1500V-12V 8.4A DDRH-120-12

Universal DC/DC converter for a wide range of applications

The DDRH-120-12 converter from MEAN WELL is a reliable device designed to convert DC voltage from a very wide input range of 250~1500V to a stable 12V. Its robust construction and advanced protection features make it ideal for both demanding industrial installations and renewable energy systems. Mounting on a DIN TS-35/7.5 or 15 rail simplifies integration into existing systems.

Key features and applications

The device is distinguished by an exceptionally wide input voltage range, making it an ideal solution for photovoltaic, wind and other systems where variable DC voltage occurs. The ability to operate at temperatures from -40°C to +80°C guarantees reliability even in extreme conditions. The converter has built-in protection against short circuit, overload, overvoltage and overheating, as well as reverse polarity protection – which minimizes the risk of damage and ensures safe operation. DC OK signaling via a relay allows for easy monitoring of the device status.

Thanks to its compact dimensions (63 x 125.2 x 115 mm), the converter can be used in limited space. This is particularly important when designing systems mounted on a DIN rail. The ability to adjust the output voltage (+20%) allows you to adapt the parameters to specific application needs.

Technical parameters and construction

The DDRH-120-12 converter delivers an output power of 120W at a voltage of 12.24V and a maximum current of 8.4A. It is characterized by high efficiency (88%) which translates to minimal energy losses. Fanless design ensures quiet operation and increases device reliability. Input/output isolation at 4kVDC guarantees safety and minimizes electromagnetic interference (EMC). The device meets the PV IEC/EN62109-1 safety standards and has CB/DEKRA, EAC, CE and UKCA certificates confirming its quality and compliance with European standards. The manufacturer's warranty is 3 years.
