PowerGuard AC-AC Frequency Converter Transformer System — 12 kVA, 60/400 Hz

The PowerGuard AC-AC Frequency Converter Transformer System is a power conversion system developed by TEDEG Defence that brings a power transformer, a frequency converter and a power distribution unit together in a single cabinet. It is designed to meet one of the most basic needs of modern defence systems: reliable, continuous power delivered to every connected system at the right voltage and frequency.

The system accepts a range of electrical inputs and produces the two output formats that military systems require: 115 VAC 400 Hz and 115 VAC 60 Hz. Total capacity is 12 kVA. Its integrated power distribution function switches seven outputs individually, so several systems and subsystems on the same platform can each be supplied with power matched to their needs.

Optimised for naval and land platforms, the unit has been developed with demanding environmental conditions and electromagnetic compatibility (EMC) requirements in mind. It is intended for defence users who expect high operational reliability and performance.

Output configuration:

Each of the seven outputs can be switched on or off with its own button on the control panel. All outputs can also be switched on or off in a single action.

Electrical performance:

Control panel:

• OLED display: fault status, alarm status and menu navigation
• Information and fault indicators: operating data and faults are shown separately on the panel
• Audible warning: built-in buzzer
• Per-output on/off buttons: individual control of each of the seven outputs
• Group control: activate-all, deactivate-all and reset buttons
• Blackout mode and silent mode

Mechanical:

Environmental durability: The unit has been assessed to military test methods covering temperature, humidity, rain, sand and dust, solar radiation, vibration, shock and EMI/EMC.

• Naval platforms: supplying shipboard systems that run on 400 Hz and 60 Hz from one cabinet, through individually switched outputs
• Land vehicles and field systems: meeting different frequency requirements on a platform with a single power conversion unit
• Mixed-frequency system architectures: reducing the need for separate transformers, converters and distribution boxes where 400 Hz and 60 Hz equipment run side by side
• Independent supply to multiple subsystems: switching off only the affected output during maintenance or a fault while other systems keep running
• Missions requiring light and noise discipline: adapting the panel to mission conditions with blackout and silent modes

The PowerGuard AC-AC Frequency Converter Transformer System combines three functions in a single cabinet: voltage conversion, frequency conversion and power distribution. Sharing 12 kVA across seven independent outputs gives the system integrator separate control over each subsystem. With efficiency above 90% and harmonic distortion of no more than 5%, connected loads receive clean, efficient power.

CAN-Bus communication links the system to the platform's control infrastructure, while the OLED display, fault indicator and buzzer let the operator see the unit's status at a glance in the field.
