- Low voltage transient capability: down to 12 V / 1s (MIL-STD-1275 Initial engagement surge)
- Built-in EMI filter for MIL-STD-461, DO160 compliance
- Output power configurations: 20 W+20 W+8 W triple or 40 W+0 W+8 W dual independent outputs
- Output voltage options: 3.3 V, 5 V, 12 V, 15 V, 24 V
- Wide operating temperature range: -40°C to +105°C
- Comprehensive protection features: reverse polarity, hold-up function, high & low input voltage transients, inrush current limit, short circuit, and over-voltage protection
The PSDG-48 series is housed in a rugged black anodized machined aluminum case, measuring 3.6" x 2.1" x 0.35" (91 x 54 x 9 mm), making it suitable for harsh environments and compliant with MIL-STD-202 & 810 for altitude, humidity, temperature shocks & cycles, mechanical vibrations, and shocks.
Optional features include individual outputs On/Off control, switching frequency sync input, startup operating temperature down to -55°C, and screening/serialization capabilities.
With a fixed high-frequency switching topology, the PSDG series offers high power density, low-profile packaging, and exceptional reliability. Its fully encapsulated design with thermally conductive resin ensures optimal power dissipation, achieving up to 87% efficiency.
