12:1 Input 60W DC-DC Converters Cover All Railway Bus Voltages

April 21, 2014 by Jeff Shepard

Gaia Converter introduces a new platform for ultra-wide-input voltage range dc-dc converters. The first introduction of this new technology platform is the 60W series, targeting railway, transportation and high-end industrial applications. Uniquely wide, the MGDDI-60 Series 12-160Vdc input voltage range is designed to cover all typical battery/bus voltages at once (24V, 28V, 48V, 72V, 96V, 110V) with the same device. This unique performance is achieved thanks to Gaia's proprietary switching techniques while also keeping efficiency over 90%.

With 2 outputs (for parallel, serial or symmetrical operation) of 5Vdc, 12Vdc, 15Vdc and 24Vdc, they can cover a wide variety of needs such as single 5- to 48-Vdc outputs, +/-15Vdc or 2 x 24Vdc outputs (30W each), for example. Packaged in the low profile industry standard 2”x3” housing, the MGDDI-60 Series has a wide temperature range of -40 to +100 degrees C and are potted to fit rugged transportation environmental conditions.

The units are full 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. Complying with EN50155/55022 or equivalent standard becomes straightforward thanks to such wide input voltage range and the use of fixed switching frequency (270kHz) with embedded LC filter. Designed for rugged applications, the MGDDI-60 series do not use optocouplers in the feedback loop.
