PowerGuard Outdoor 115 VAC 60/400 Hz Military Mobile Frequency Converter

The PowerGuard Outdoor combines four key characteristics in a single chassis:

• ✅ 60 Hz + 400 Hz dual-frequency conversion — in the same system
• ✅ Tested to MIL-STD-810G CHG-1 and MIL-STD-461E — temperature, vibration and shock tests and EMI/EMC tests passed at an ISO/IEC 17025 laboratory (reports V 1731 23228 00 00 BE and A 1731 23228 00 01 BE); outdoor design for rain, dust and humidity
• ✅ Shipboard power systems compliance (MIL-STD-1399B) — for land and naval platforms
• ✅ Smart PDU + Ethernet remote control — integrated, not a separate module

🏆 **Field example: Land Rocket Platform →** — A single PowerGuard Outdoor replaced three separate systems.

The PowerGuard Outdoor 115 VAC 60/400 Hz Military Mobile Frequency Converter combines three critical capabilities required by modern defence platforms in one compact military-grade system: frequency conversion (50 Hz ↔ 60 Hz / 400 Hz), isolated AC-AC power conversion, and a smart power distribution unit (PDU). It is designed for outdoor field deployment by TEDEG Defence.

The unit converts a 3-phase 360–440 VAC, 50 Hz mains supply to the 115 VAC 60 Hz and 115 VAC 400 Hz output formats required by military equipment, delivering high stability with low harmonic distortion. 12 kVA total capacity is distributed across 7 isolated outputs.

Core features:

• Static double-conversion + IGBT PWM architecture — no moving parts; clean, isolated and stable power output
• Dual OLED display (Info + Fault) + colour-coded physical buttons; front panel with activate/deactivate all, silent mode, reset and buzzer
• Ethernet web server + desktop GUI software (Ethernet and RS-422 communication via KN9)
• Real-time V/A/Hz monitoring — all inputs and 7 outputs
• Overload performance — 125% → 5 min, 200% → 5 sec, 250% → 1 sec (0.8 PF)
• MIL-DTL-38999 military connectors (outputs and communication); KN1 power input MIL-DTL-5015 type, 22-22 shell

• MIL-STD-1399B — Naval platform power interface compliance

Defence — land and naval platforms:

• Mobile command-and-control vehicles — field C2 containers, mobile operations centres
• Field communications vehicles — tactical truck power distribution
• Naval platforms — ship auxiliary power systems (MIL-STD-1399B compliant)
• Forward operating bases and mobile military camps — continuous 60 Hz supply
• Field hospitals and surgical containers — critical medical equipment supply
• Temporary military base and camp infrastructure — 24/7 mobile power system

Industrial and test:

• Test and calibration laboratories — 60 Hz and 400 Hz dual-frequency requirement (military equipment testing, motor calibration, naval device verification)
• Special military motors and servo drives — land/naval equipment requiring 400 Hz frequency
• Precision production lines — processes requiring power stability
• Data centres and field IT containers — power supply for critical IT infrastructure

1. 1.Dual frequency in one system — 60 Hz + 400 Hz in the same chassis, no separate converter required
2. 2.Smart built-in PDU — 7 independent isolated outputs auto-switched by load
3. 3.Ethernet web server — browser access without additional software
4. 4.Real-time V/A/Hz monitoring + instant alarm notifications
5. 5.Dual OLED + colour-coded physical buttons — practical operator interface
6. 6.Static double-conversion + IGBT PWM — stable sine wave with < 5% THD
7. 7.Overload resilience — at 0.8 PF: 125% → 5 min, 200% → 5 sec, 250% → 1 sec
8. 8.Military standards compliance — MIL-STD-810G and 461E tested at an accredited laboratory + MIL-STD-1399B shipboard power

The MIL-STD-810G CHG-1/810F and MIL-STD-461E tests behind the PowerGuard Outdoor were carried out by Consept Europe Kft., accredited to ISO/IEC 17025, at its Gebze test site. Both reports conclude that the product passed all tests in scope, and the full reports are shared on request.

MIL-STD-810G CHG-1 / 810F, environmental — report V 1731 23228 00 00 BE (20 December 2024):

MIL-STD-461E, EMI/EMC — report A 1731 23228 00 01 BE (11 December 2024):

Rain, dust and humidity resistance is part of the outdoor design stated in the datasheet; the reports cover the methods listed above.

PowerGuard Outdoor and the AC-AC Frequency Converter Transformer System both deliver 12 kVA through seven outputs: 2 × 115 VAC 400 Hz and 5 × 115 VAC 60 Hz. They differ in how they are deployed, connected and monitored:

Choose the Outdoor as a free-standing field unit monitored from a browser or over Ethernet; choose the Transformer System when transformer, conversion and distribution should sit in one cabinet wired into a vehicle or platform and reporting over CAN-Bus.

PowerGuard Outdoor is an indigenous engineering solution that combines 60 Hz + 400 Hz dual frequency, 7 isolated outputs, a smart PDU, Ethernet remote control and an outdoor design in a single chassis. A complete solution in one 270 ± 5 kg unit for field mobile command, land/naval platforms, and precision test laboratories.

For one cabinet with an output adjustable between 60 and 400 Hz and a choice of star or delta connection, see the 400 Hz static frequency converter.
