Aerospace, defense, and high-precision industrial applications demand power at 400Hz frequency—significantly higher than standard mains supply. EnerTech’s Static Frequency Converter 50 Hz to 400 Hz transforms conventional 50Hz grid power into stable, high-frequency 400Hz AC, eliminating the need for expensive dedicated power infrastructure.
Designed specifically for aviation ground support, military equipment, CNC machine tools, and laboratory testing environments, this converter delivers the specialized power characteristics required by advanced electrical systems where size, weight, and reliability are critical.

Higher frequency enables dramatic reduction in transformer and motor core sizes. Aviation equipment leverages 400Hz to achieve critical weight savings in aircraft electrical systems.

At 400Hz, reactive impedance increases, allowing smaller wire gauges and reduced copper content in transformers and motors—essential for aerospace weight optimization.

Equipment designed for 400Hz delivers superior dynamic performance with quicker acceleration, better speed control, and enhanced precision compared to 50Hz or 60Hz alternatives.

High-frequency operation reduces magnetic core losses and enables more compact, efficient electromagnetic devices throughout the electrical system.

Power aircraft during maintenance, testing, and pre-flight preparations with GPU-compatible 400Hz output. Eliminate dependency on aircraft auxiliary power units, reducing fuel consumption and maintenance costs during ground operations.

Supply specialized power to radar systems, communication equipment, mobile command centers, and weapons testing facilities. Meet MIL-STD power quality requirements for mission-critical electronic systems.

Drive high-precision spindle motors and servo systems that require 400Hz for optimal performance. Achieve superior surface finishes and dimensional accuracy in aerospace component manufacturing.

Create controlled test environments for 400Hz equipment qualification and compliance testing. Simulate aircraft electrical systems for avionics development and validation programs.

Power specialized hermetic compressors designed for 400Hz operation. Achieve higher efficiency and reduced size in industrial and commercial refrigeration applications.

Supply dockside power to military and research vessels equipped with 400Hz electrical systems. Enable maintenance and system testing while minimizing onboard generator operation.

Microprocessor control delivers precise output regulation, advanced protection algorithms, and comprehensive diagnostics. Real-time monitoring enables predictive maintenance and maximizes equipment uptime.

Advanced filtering and PWM control techniques maintain low total harmonic distortion (THD), protecting sensitive electronic loads from power quality issues.

Comprehensive safeguards include overvoltage protection, undervoltage lockout, overcurrent limiting, overtemperature shutdown, and short-circuit fault detection.

Controlled inrush current limiting prevents nuisance breaker trips during converter startup. Gradual voltage ramp-up extends equipment lifespan and improves grid compatibility.

Intelligent cooling systems with temperature monitoring prevent thermal stress on power semiconductors. Extended component life and consistent performance across ambient temperature ranges.
