New for 2025: Revision B1 introduces an improved connector design with full backward compatibility.
The SPP-F330A Rev B1 is a Smart Power Protector developed by Gilgal Power Engineering Ltd for demanding military, industrial, and vehicular environments.
It replaces traditional electromagnetic circuit breakers and external protection diodes, providing a compact and intelligent layer of protection against reverse polarity, surges, and spikes — fully compliant with MIL-STD-1275 A/B/D/E/F and MIL-STD-704 A/B/D/E/F.
⚙️ Power, Precision, and Efficiency
The SPP-F330A Rev B1 delivers up to 30 A (≈ 1000 W @ 28 VDC) with up to 99 % efficiency and an internal resistance of only 15 mΩ.
It continuously monitors input voltage and disconnects safely when it exceeds 36 V, protecting mission-critical loads.
When in OFF mode, the quiescent current is nearly zero, and the unit provides a remote enable input for seamless integration into BMS controllers, DC-DC converters, and Power Distribution Modules (PDMs).
🧰 Military-Grade Compliance and Environmental Endurance
The SPP-F330A Rev B1 meets the toughest environmental standards of MIL-STD-810E, including:
-
Operating temperature: −40 °C to +85 °C
-
Vibration: 20 g’s (Category 6)
-
Acceleration: 9 g’s
-
Shock: 40 g’s
-
Operating altitude: 40,000 ft
An optional COT (Conformal Coating) version is available for 95 % humidity and dusty conditions.
🔌 Revision Upgrade – New Connector, Higher Reliability
Revision B1 introduces a major mechanical enhancement: the connector has been upgraded from a circular FCT W2 to a D-Sub 15-Pin by Adam Tech (DA15-PL-24).
This change improves connection stability, increases current-carrying surface area (six pins in parallel), and simplifies maintenance.
External dimensions remain identical, ensuring mechanical compatibility while requiring a new mating cable or adapter.
