MEAN WELL Isolated DIN Rail DC/DC Converter, 12V 2.5A, 30W

The MEAN WELL DDR-30G-12 is a compact and highly efficient 30W DIN rail mounted DC-DC converter from the DDR-30 series. Designed for robust industrial applications, it features an ultra-slim 35mm width for space-saving installations within control panels and enclosures. Its core strength lies in a 4:1 ultra-wide input voltage range (9-36VDC), providing exceptional flexibility for various power sources, and a high 4kV DC isolation between input and output for enhanced system safety and noise immunity.

This converter offers a fixed 12V DC output with a rated current of 2.5A and includes a ±10% output voltage adjustment capability for fine-tuning. It operates with a typical efficiency of 86% and requires no minimum load, making it highly versatile and energy-efficient. Cooling is achieved through reliable air-free convection, ensuring silent operation without the need for fans.

Comprehensive Protection & Reliability

Engineered for durability in demanding environments, the unit is equipped with a full suite of protective functions. These include short circuit, overvoltage, and overload protection, as well as input reverse polarity and input undervoltage protection, safeguarding both the converter and connected equipment from electrical faults. It operates reliably across an extensive temperature range from -40 to +85°C.

Approvals & Applications

The DDR-30G-12 carries major international safety approvals, including UL/IEC 62368-1 and AS/NZS 62368.1, with a design reference to UL508. This makes it a trusted component for a wide array of critical systems. Its primary functions include acting as a DC buck/boost regulator, increasing system insulation levels, and compensating for voltage drop along long cable runs.
