Mil-Spec AC/DC Converter — Defense-Grade Power Supply

The Mil-Spec AC/DC Converter is TEDEG Defence's defence-grade AC-DC power conversion family for the military sector. Fully sealed and fanless architecture delivers silent, maintenance-free operation in environments exposed to rain, dust, vibration and shock. As the PowerGuard-A Series it covers the PowerGuard-A1000 (single-phase, 24 VDC / 1 kW) and PowerGuard-A 380 (three-phase, 28 VDC / 1–4 kW) models; a fanless, conduction-cooled, fully sealed aluminium enclosure, MIL-DTL-38999 Series III connectors, active power factor correction and MIL-STD-810 / MIL-STD-461 compliance are the family's common design principles.

Architectural features:

• Fully isolated AC-DC conversion — high voltage isolation
• Conduction-cooled — fanless, silent
• Fully sealed aluminium enclosure — IP67
• MIL-DTL-38999 Series III connectors — keyed, 360° EMI-shielded
• Active power factor correction (PFC) — PF ≥ 0.99 at 50/60 Hz, low harmonics

Configuration flexibility:

• Single-phase 90–265 VAC, 45–420 Hz (A1000) or three-phase 360–440 VAC, 47–63 Hz (A 380) input
• Output voltage: 24 VDC (A1000) or 28 VDC nominal, 12–48 VDC configurable (A 380)
• Power classes: 1 kW to 4 kW — single-output 1 kW (A1000) or 1 / 2 / 3 / 4 kW with 4 independent outputs (A 380)
• Communication: Ethernet · CAN-Bus · RS-485 (optional on A1000); Remote Commander control box (A1000, optional) or software interface and remote control (A 380)
• DC input (outside this AC-DC family): for a 12 VDC vehicle bus, the mil-spec DC-DC converter PowerGuard-D1000 delivers 24 VDC / 1 kW; all models are compared under military AC-DC and DC-DC converters.

Military compliance:

• MIL-STD-810 environmental compliance — dust, moisture, vibration, shock
• MIL-STD-461 EMI/EMC — electromagnetic compatibility
• MIL-DTL-38999 connector — reliable field connections

• Military vehicles — turret electronics, communications, sensors
• Mobile command units — field C2 electronic infrastructure
• Radar systems — antenna-station auxiliary power
• Naval platforms — shipboard auxiliary DC power
• Tactical communications — radio, SATCOM, crypto systems

The Mil-Spec AC-DC Converter family — including PowerGuard-A1000 (1 kW single-phase, 24 VDC) and PowerGuard-A 380 (1–4 kW three-phase, 28 VDC, 4 independent outputs) — represents TEDEG Defence's flagship power-conversion offer for the defence industry, all under one engineered architecture. NCAGE: TM885, ITAR-Free. Indigenous manufacturing + Turkish R&D + field service support = meaningful total value for NATO-country buyers.
