Intelligent Protection for Critical Electrical Systems: Smart Power Protector

In the world of military and industrial engineering, electrical system protection components must comply with strict standards of reliability and performance. Among the most established and widely used solutions are circuit breakers, certified under the following standards:

MIL-PRF-39019 – A stringent standard for breakers used in military applications
MIL-STD-55629 – Defines additional mechanical and electrical requirements for critical systems.

These breakers have proven themselves over many years in demanding environments: they are compact, provide fast and reliable response, and are suitable for a wide range of applications. As technology evolves, complementary solutions have emerged to provide additional layers of protection—particularly in an era of intelligent, fast-response, and communication-shielded systems.

The graph illustrates the response of an SPP system to an input surge event:

• Input voltage (Vin) spikes from 28V to 100V for a brief period (1–1.2 ms)
• Output voltage (Vout) remains protected and clamped at 36V during the disturbance

This clearly demonstrates the clamping and protection capability – a critical function to safeguard sensitive equipment.

The chart shows the relationship between load current and efficiency of the SPP unit across three typical input voltages: 18V, 28V, and 32V.

It highlights the exceptionally high efficiency of the component — nearly 99.5% at high loads — which underscores the thermal and energy advantage of using an SPP versus traditional solutions.

Key Capabilities of SPP Units

Technical Advantages vs Traditional Circuit Breakers

Common Use Cases for SPP

• Tactical military communication systems
• Mobile command posts
• Military land vehicle power panels
• Robotic platforms and field equipment
• Aerial systems (UAV/UCAV)
• Mobile power stations
• RF or radar systems
• Control units for unmanned platforms
• Active protection systems (APS)

Standards Compliance

SPP units are designed in compliance with the following military standards:

• MIL-STD-1275F – Spike & Surge in ground systems
• MIL-STD-704 – Aircraft power supply systems
• MIL-STD-461 – EMI/RFI conducted & radiated emissions
• MIL-STD-810 – Physical endurance under harsh conditions

Conclusion
