Mean Well’s DDRH Series Isolated Ultra-Wide Input Multi-installation selectable DC/DC Converters Now Available at TTI
Suitable for EV charging equipment applications and DC power distribution systems
TTI, Inc. – Europe, a leading speciality distributor of electronic components, is now stocking the DDRH series of DIN Rail mount DC/DC converters from Mean Well. The DDRH-15/30/45/60 (15W, 30W, 45W and 60W, respectively) units can accept voltages ranging from 150 to 1500Vdc, which can supply a stable working voltage, making them suitable for applications with diverse DC voltage conversion requirements. Target applications include solar and wind generation installations, energy storage systems (ESS), EV charging stations, and DC power distribution systems.
The DDRH series offers a high isolation level of 4KVac, as well as undervoltage and reverse polarity protection for the input and protection against short circuits and overload and overvoltage conditions, which enhance the safety and protection of electrical installations. Additionally, the 60W DDRH-60 series has overtemperature protection and meets EN 55032 Class A EMI performance without needing external components.
The convection-cooled design ensures silent operation, making the DDRH series suitable for noise-sensitive environments. Fanless cooling also reduces dust intake and failure rate. They can operate in a temperature range from as low as -40°C to +80°C, with the ability to work at +50°C at full load without derating. Output voltages range from 5V up to 48V depending on the power rating, and the 60W DDRH-60 series comes with a built-in potentiometer that allows designers to trim the output by ±20%.
The DIN Rail type units can be easily installed on TS-35/7.5 or 15 DIN rails, simplifying the installation process. The DDRH-15/30/45 series are also available for PCB mounting and mounting with screw terminals. These converters can operate at altitudes of up to 5000m, making them suitable for installations in countries with high elevations. All units in the DDRH series are designed to meet IEC/EN 62109-1 and UL 1741 (by request), ensuring their compliance with safety and regulatory standards.
