AC/DC Dönüştürücü
PowerGuard-A1000 is a high-efficiency, fanless AC-DC power conversion unit developed by Tedge Defence for use in demanding military and field environments.
It operates from a single-phase 99 – 264 VAC input over a 45 – 420 Hz frequency range and delivers a regulated 24 VDC / 1 kW continuous output, sustaining full-load operation up to +55°C without derating.
With its fully sealed aluminum enclosure and conduction-cooled baseplate, the PowerGuard-A1000 is designed for outdoor and vehicle use under rain, dust, vibration, and shock.
The fanless design eliminates moving parts, ensuring silent operation, high reliability, and minimal maintenance over long-term missions.
Power and signal interfaces utilize MIL-DTL-38999 Series III connectors for environmental sealing and EMI integrity.
Optional Ethernet, CAN-Bus, or RS-485 communication interfaces enable remote monitoring, configuration, and diagnostic reporting.
A rugged Remote Commander Control Box accessory allows remote ON/OFF control and alarm reset in field conditions.
The PowerGuard-A1000 is designed to meet MIL-STD-810 (environmental) and MIL-STD-461 (EMC) requirements, providing reliable 24/7 power delivery for military vehicles, mobile command units, radar systems, and tactical communication platforms.

GELİŞMİŞ ÖZELLİKLER
Fanless and Fully Sealed Design
The PowerGuard-A1000 is built with a fully sealed aluminum enclosure and a fanless thermal architecture, ensuring reliable operation under dust, moisture, vibration, and shock.
All heat is dissipated through a conduction-cooled baseplate, enabling silent operation and zero maintenance in harsh environments.
Wide Input Frequency Range (45–420 Hz)
The converter supports both standard 50/60 Hz and high-frequency 400 Hz military power grids.
At elevated frequencies, power factor decreases slightly, but overall system performance remains stable when properly filtered at the system level.
Active Power Factor Correction (PFC)
An integrated PFC circuit ensures PF > 0.99 at 50/60 Hz operation, minimizing input harmonic distortion and maximizing efficiency.
At 400 Hz input, PF typically ranges from 0.75 to 0.8, and this should be considered when sizing fuses, cabling, and EMI filters.
Rugged MIL-DTL-38999 Connectors
All power and signal interfaces utilize MIL-DTL-38999 Series III connectors for 360° EMI shielding, vibration resistance, and environmental sealing — ideal for harsh military applications.
Remote Monitoring & Control (Optional)
Optional Ethernet, CAN-Bus, or RS-485 interfaces allow remote monitoring, configuration, and diagnostics.
A Remote Commander Control Box accessory provides remote ON/OFF functionality and alarm reset for field operations.
MIL-STD Compliance
PowerGuard-A1000 is designed to meet MIL-STD-810 (environmental) and MIL-STD-461 (EMC) standards.
Its sealed, IP67-rated housing ensures reliable operation in outdoor or vehicle-mounted systems exposed to dust, water, and mechanical stress.
