GAIA Launches Family of 500 W Integrated Power Supplies for High-Reliability Applications

­GAIA Converter, a leading provider of high-efficiency, high-reliability DC/DC converters and modular power solutions, has announced the launch of the GRD-50A-M series of scalable 500 W integrated power supplies for high-reliability markets such as military and aerospace. 

This new family of commercial-off-the-shelf board power supplies, designed for 24 Vdc and 28 Vdc input, complies with major military standards, including MIL-STD-1275, MIL-STD-704, and MIL-STD-461. The GRD-50A-M provides flexibility, robustness, and easy integration into high-demand systems, therefore reducing time-to-market. It is suitable for a broad range of military and aerospace applications across land, sea, and air, including military vehicles, avionics, high-power lighting, and directed energy weapons. 

Key specifications and features include a 16-38 Vdc permanent input voltage with transient voltage protection of up to 100 Vdc, as well as reverse polarity and overload protection. The power supplies offer a total output power of 500 W with 12 Vdc, 15 Vdc, 24 Vdc or 28 Vdc output voltage. 

The GRD-50A-M series features an overall efficiency of 89 %, with full protection for output short circuit (hiccup mode), overvoltage, and overtemperature. The series features 1500 Vdc primary-secondary isolation and 500 Vdc chassis ground isolation. 

Overall board dimensions are 10" x 2.75" x 0.9" (255 x 70 x 24.25 mm) and operating temperatures extend from -40 °C to +85 °C base-plate. Furthermore, the GRD-50A-M comes in a range of different configuration options, including board only (/B), coated (/V), and parallel (/P). 

"This complete, ready-to-deploy power supply is engineered specifically for the demanding requirements of defence and high-reliability systems,” says Christian Jonglas, Technical Support Manager at GAIA Converter. “This innovative circuit board assembly delivers robust DC power while meeting all critical military standards right out of the box. By integrating this capability into a single, compact solution, we are helping our defence and aerospace customers accelerate their development timelines while ensuring mission-critical reliability."
