PowerGuard-A 380 VAC-28 VDC Askeri AC-DC Dönüştürücü ve Dağıtım Sistemi

PowerGuard-A Series is a high-reliability, military-grade 3-phase AC power conversion and intelligent power management system developed by Teled Defence for demanding field, vehicle, and outdoor operations. It rectifies a wide-range 360–440 VAC three-phase input into a stabilized 500–800 VDC high-voltage DC bus, and subsequently converts this bus into configurable 12 / 24 / 28 / 36 / 48 VDC regulated outputs across power classes from 1 kW to 4 kW, delivering continuous full-load performance even under extreme thermal and environmental conditions.

Built around a high-efficiency architecture and a ruggedized, conduction-cooled thermal design, the system maintains stable output regulation during long-duration and mission-critical operations. Its fully sealed IP67 aluminum enclosure eliminates airflow paths, preventing the ingress of dust, mud, humidity, and rain. Passive heat dissipation is achieved through an engineered conduction path that transfers thermal energy directly to the host platform structure—ensuring silent operation and zero maintenance throughout the unit’s lifecycle.

Açıklama

The PowerGuard-A Series is not only a power converter but also a smart power distribution and control hub. Each output channel can be monitored and controlled remotely through optional Ethernet, RS-485, or CAN-Bus interfaces, providing real-time telemetry for voltage, current, temperature, and system health. Remote switching, output enable/disable, load diagnostics, and alarm reset functions allow seamless integration into centralized vehicle or platform management systems.

Engineered to comply with MIL-STD-810 environmental and MIL-STD-461 EMC requirements, the PowerGuard-A Series delivers secure, uninterrupted power to mission-critical subsystems deployed in armored vehicles, radar shelters, mobile command units, naval platforms, and rugged outdoor power infrastructure.

GELİŞMİŞ ÖZELLİKLER

Multi-Voltage Configurable Outputs

Supports selectable and independent DC output configurations:
12 / 24 / 28 / 36 / 48 VDC, enabling the same hardware platform to power a wide range of mission equipment and subsystems.


Intelligent Power Management Controller

A dedicated embedded controller provides real-time monitoring and control of all power channels, including:

  • Output voltage & current telemetry

  • Fault & alarm reporting

  • Thermal diagnostics

  • Remote enable/disable of each output


Advanced Remote Communication Interfaces

Optional digital interfaces include:

  • Ethernet (TCP/UDP-based protocol)

  • RS-485 (Modbus / custom protocol)

  • CAN-Bus (J1939 / CANopen-style messaging)
    These allow full system integration into vehicle or platform control networks.


Fully Sealed IP67 Military Enclosure

The aluminum monolithic IP67 chassis provides:

  • Zero air ingress

  • Zero moisture ingress
