GAIA launches integrated power supplies for high-reliability applications
GAIA Converter 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).
