How has Gaïa made this possible
The MGDDI-series 20W and 60W DC/DC converters from Gaïa are suitable for applications in the Railway-, transport- and high-end industry thanks to it’s ultra wide input voltage range from 12 up to 160 VDC. Uniquely wide, the MGDDI-20 Series input voltage range is ideal to cover all typical battery/bus voltages at once (24V, 36V, 48V, 72V, 96V, 110V, 125V) with the same device. This unique performance is achieved thanks to Gaia’s proprietary switching techniques also allowing to keep efficiency as high as 90%.
Why is the MGDDI-series optimal for so many different applications:
With 2 isolated outputs (for parallel, serial or symmetrical operation) of 5 VDC, 12 VDC, 15 VDC and 24 VDC, they can cover a wide variety of needs such as single 5 to 48V output, +&- 15V or 2x24V outputs for example.
Packaged in a low profile industry standard housing, the MGDDI-20 Series have a wide temperature range of -40°C to +100°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
- 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-20 series do not use.
