Hi-Rel DC-DC converters

30 April 2019 Power Electronics / Power Management

Gaia Converter has extended its platform of DC-DC converters with ultra-wide input voltage, with the new Hi-Rel MGDD-80 series targeting military and airborne applications.

The devices’ 9-60 V input voltage range (80 V transient) is ideal to comply with Mil-Std-1275, 704 or DO-160 standards without an additional front-end protection device. This performance is achieved thanks to proprietary switching techniques while also keeping efficiency over 90%.

With two outputs (for parallel, serial or symmetrical operation) of 5 V, 12 V, 15 V and 24 V, they can cover a wide variety of needs, such as single 5 to 48 V output, ± 15 V or 2 x 24 V outputs, for example. Packaged in a 5,08 x 4,06 cm housing, they have a wide temperature range of -55°C to +105°C and are potted to suit rugged military and airborne environmental conditions.

The units are fully featured and protected, with zero to full-load regulation, trim, on/off capability, adjustable UVLO, soft start, embedded EMI filter, as well as over-current and over-temperature protection. They can also be synchronised, and do not use any optocoupler.
