A Technical & Systems-Level Overview by Amironic Ltd – Exclusive Representative of Gilgal Power Systems

1️⃣ The Silent Revolution in Military Power Systems

Over the last decade, the world of power electronics has undergone a profound transformation.
The rapid increase in energy-hungry subsystems — sensors, stabilized platforms, high-bandwidth communication nodes, embedded computers, and autonomous modules — has turned the DC power supply from a secondary component into a mission-critical core element.

In the past, an armored vehicle consumed a few dozen amps.
Today, its vision systems, gimbals, computers, AI processors, and RF communication blocks require hundreds of watts, and all of it must remain fully operational during:

• Engine cranking

• Battery switching

• Bus collapses

• Repeated transient spikes

• Near-strike lightning events

In simple terms:

In a military platform, electrical stability is not a convenience — it is the difference between mission success and system blackout.

This is exactly where Amironic Ltd, the exclusive representative of Gilgal Power Systems, enters the picture.
Gilgal is one of the very few manufacturers worldwide that fully comply with MIL-STD-1275F, not just E.

The “F” revision is a game changer. Unlike previous versions, 1275F requires not only survivability but continuous operation (Ride-Through) during repeated, rapid transients — multiple surge events, reverse transients, and partial line interruptions.

Where typical industrial supplies collapse —
Gilgal power supplies keep running.

2️⃣ Power Integrity in Harsh Environments – The Real Engineering Challenge

System engineers know:
Power Integrity is not just “low noise.”
It is the ability to maintain stable voltage and current despite an electrically hostile environment.

In ground and aerial platforms, the threats fall into three main categories:

2.1 Fast Electrical Events – Surge & Spike

Engine start and battery replacement can generate severe voltage spikes — sometimes +100 V for ~1 ms.

MIL-STD-1275F requires the power supply to not only survive the event but maintain a stable output with zero interruption (Functional-Through).

To achieve this, Gilgal implements a multi-stage protection chain:

• TVS Diodes – instant absorption of transient energy

• MOSFET Active Clamp – prevents overshoot

• Multi-Stage LC Filtering – eliminates reflected noise from the vehicle bus

2.2 Reverse Polarity Events

Field installations, rapid battery swaps, and cable mis-wiring may accidentally reverse polarity.
Gilgal integrates bi-directional MOSFET ORing with automatic recovery — meaning even if polarity is reversed, the unit does not suffer permanent damage.

2.3 Extreme Physical Environments

Moisture, dust, mud, shock and vibration can cause leakage currents, cracked solder joints, and insulation failures.

To counter this, Gilgal units are:

• Fully sealed to IP67

• Equipped with base-plate cooling that removes heat and prevents condensation

• Built from hard-anodized aluminum (Al6061-T6)

• Filled with thermal potting compound for mechanical damping and heat conduction

🧩 Result: Military-grade Performance

• EMI and ripple levels 10× lower than required by standards

• Component temperature 15–20 °C lower than open-frame commercial supplies

• MTBF exceeding 100,000 hours @ 40°C

Surge Immunity – Input vs Output During a MIL-STD-1275F Event

3️⃣ Gilgal & Amironic Design Philosophy – “Survive and Serve”

Gilgal’s engineering approach is built on three core principles:

3.1 Total Sealing – Environmental Immunity

Every unit is manufactured as a solid sealed block.
No ventilation slots, no fans, no dust ingress — nothing that can fail.

Cooling is achieved through the bottom base-plate, which connects directly to the system chassis.
This enables installation inside weapon pods, armored vehicles, or sealed avionics enclosures.

Advantage: Zero maintenance. Zero points of failure.

3.2 Ruggedization – Physical & Electromagnetic Resilience

Mechanical design meets MIL-STD-810G:

• Vibration resistance up to 40 g SRS

• Mechanical shock up to 75 g Half-Sine

• Components rated for –55°C to +125°C

• Units tested with HASS and 125°C burn-in

EMI/EMC design meets MIL-STD-461F through:

• Internal Faraday-Cage architecture

• Tight component layout to reduce loop area

• Balanced switching topologies (Push-Pull)

• Multi-stage filtering and segregated power/control paths

3.3 Smart Control & Monitoring

Gilgal units are not “black boxes.” They offer:

• I²C monitoring (voltages, currents, temperatures)

• Remote ON/OFF control

• Status outputs for under/over-voltage detection

This enables seamless integration into system-wide Health Monitoring frameworks — essential for ISR, C4I, and autonomous vehicles.

5️⃣ MIL-STD-1275F – The Standard That Separates Success from Failure

Most manufacturers claim compatibility with MIL-STD-1275E.
Very few pass 1275F.

Why 1275F Is Different

• Requires Ride-Through continuity

• Requires handling repetitive transients, not a single event

• Requires thermal behavior validation under multiple surge sequences

Gilgal is one of the rare manufacturers that passed F-level testing.
Its units maintain stable output even under repeated +100V / 1ms surges every 500 ms.

The graph shows the efficiency profiles of Gilgal’s three power-supply families across the full load range.
The Rugged series achieves the highest efficiency, while the Sealed and Triple Output units provide stable and predictable performance.
The curves highlight a low-loss design and optimal operating behavior, especially in the typical working range of most systems (40–70% load).

6️⃣ Choosing the Right Solution

The difference: Gilgal power supplies maintain 100% output power up to +65°C, while a typical industrial supply begins losing power already at +50°C.

7️⃣ Thermal & EMC Engineering – The Heart of Long-Term Reliability

Most failures in military systems are thermal, not electrical.

Gilgal combats this with:

7.1 Base-Plate Cooling

• No fans → no mechanical failures

• Up to 20°C lower component temperature

• Full IP67 sealing

• Zero airflow → reduced vibration

(Insert your derating graph)

7.2 Multilayer EMI Shielding

• Internal Faraday containment

• Balanced switching

• LC + ferrite + common-mode filtering

• Segregation between high-current and control domains

The graph shows a comparison of conducted EMI between a typical industrial power supply (dashed line) and a military-grade Gilgal power supply (solid line).
The X-axis represents frequency (10 kHz – 10 MHz), and the Y-axis represents noise level in dBµV.
The red line indicates the MIL-STD-461 CE102 compliance limit.
It is clearly visible that the Gilgal supply maintains significantly lower noise levels than the requirement — demonstrating full compliance with military EMC standards.

7.3 Vibration Damping with Thermal Potting

Potting compound advantages:

• 2.1 W/m·K heat conduction

• Absorbs vibration up to 40 g SRS

• Prevents cracking, moisture, dust ingress

Conclusion

In environments where every electrical disturbance can shut down a critical subsystem, only a fully MIL-STD-1275F-compliant, sealed, ruggedized, and intelligently monitored power system can be considered truly military-grade.
