DC/DC Converters.

The Mean Well DDRH series of DIN Rail mount DC/DC converters are now been stocked by TTI - Europe. 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.

DC:DC Converters

Ideal Power are now offering a wide range of DC/DC converters from Glary Power Technology, one of the leading innovators of small footprint board mounted power conversion. Glary are renowned worldwide for producing extremely reliable power converters that exceed 90% efficiency, are thermally efficient and have an impressive power density to size ratio. These innovative DC/DC converters are available in industry-standard encapsulated and “brick” form factors ranging from 40W to 2KW and are ready to be fully customised to meet individual project requirements.

Established in 1998, Glary have proved to be a reliable source for electronic design engineers seeking uncompromising PCB mounted power solutions. Glary offer a unique combination of industry-leading design, immense reliability and superior technical knowledge. The Glary business model is built on patents pushing the boundaries of technology by exceeding expectations for the design and manufacture of DC/DC converters.

Patented Buck Reset Forward Technology exclusive to Glary, improves synchronous rectification (SR) operation by reducing the amount of components required. Achieved through a technique which improves the efficiency of rectification by replacing diodes with actively controlled switches, usually power MOSFETs or power BJTs, this innovative and unique topology design reduces heat generation, improves thermal efficiency through equal heat distribution and allows an incredible amount of power to be available.

Reducing the footprint required by the power supply on a PCB provides a major benefit for system hardware design as other system and application critical components can reclaim the saved space.

Glary’s Continuous improvement of designs to produce market-leading products provides an impressive feature-rich product with fewer components on system board, faster transient response, lower ripple and lower RFI noise, no Tantalum capacitors are used increasing reliability, high power density in a small form factor, along with extremely low heat generation and power loss. Single-sided component layout allows for easy mounting on the base-plate, Sink-Plate options eliminate the need for extra heat-sinks, vertical or horizontal heat-sink fins may be specified to increase compatibility with system air-flow and smooth and precise edges of the base plate allow for compact assembly.

When a new design is commissioned or a modification to an existing product is required, the UK based IP Support Engineering Team at Ideal Power work together with Glary Technology. Ideal Power become a technical partner to the customer’s in-house design engineers to match the exact application power requirements. The IP Support team has over 40 years of experience in the power supply industry and provides local assistance throughout the whole design process from concept, design, quotations, samples and testing to approvals and standards compliance, shipping, stock-holding and after-sales service.
