PowerGuard 400/115 VAC AC-AC Military Inverter — 10 kVA, 4 Outputs

The PowerGuard 400/115 VAC AC-AC Military Inverter (Part No: TDG-PFC-A0000) is a military-grade power converter that turns a 3-phase 400 VAC, 50–60 Hz supply into a 115 VAC, 50 Hz output. It splits a total of 10 kVA across four separate outputs: two 3-phase and two 2-phase 115 VAC outputs.

The "400" in the name refers to the input voltage. The unit does not produce 400 Hz; all outputs are 50 Hz. This means 115 VAC equipment can be powered directly at a site, camp or platform connected to a 400 VAC grid.

The output is delivered through an isolated output transformer, which provides high-voltage insulation between input and output. All input and output connections use MIL-DTL-38999 and MIL-DTL-5015 series military connectors. The Ethernet interface on KN6 allows the unit to be monitored and switched on and off remotely.

The system is designed for indoor and outdoor use and has passed MIL-STD-810G testing. Its resistance to dust, humidity, rain, vibration and shock provides reliable power conversion for field operations, mobile mission systems and forward bases.

Inputs and outputs:

Power and protection:

Monitoring and control:

• BIT (Built-In Test) for status monitoring
• Monitoring and remote on/off control over Ethernet (KN6)
• Real-time readout of input and output values; monitoring and control of output voltages and currents
• OLED information and fault display
• A separate colour-coded button for each output and a user-friendly interface
• Desktop remote control and monitoring software over Ethernet: Shows input phase voltages (R, S, T) and phase currents, plus output voltages and currents. Commands to the output units, including an emergency command, are sent from the software.

Environmental and mechanical:

Military standards:

• MIL-STD-1399B: Technical standard compliance
• MIL-STD-810G: Environmental durability

Defence and field:

• Field operations and mobile mission systems: Supplying 115 VAC equipment from a 400 VAC source, with fast power conversion
• Forward outposts and temporary military bases: 115 VAC power source for camp infrastructure
• Naval platforms: Supplying 115 VAC shipboard equipment, backed by MIL-STD-1399B compliance
• Specialised military motors and power-intensive equipment: Mission equipment with high energy demand

Industrial and critical infrastructure:

• Test and calibration laboratories: Test equipment that needs precise power
• Heavy industry and automation: Large industrial motors and control systems
• Data centres: Continuous supply for servers and storage
• Emergency and disaster management: Transportable power source

PowerGuard 400/115 combines four outputs sharing 10 kVA, an isolated output transformer, a dedicated colour-coded button for each output and remote control over Ethernet in a single cabinet. Supplying 3-phase and 2-phase loads from their own connectors makes it easier to manage different load groups separately. Its overload capability gives headroom of up to 250% for short peaks.

For equipment that needs 400 Hz power, see the PowerGuard 115/200 VAC 400 Hz Static Frequency Converter; for 400 VAC distribution, see the PowerGuard AC Power Distribution Panel.
