Complete Test Solution for 400Hz Power Supply Systems in Aviation & Military Industries
Matched with dedicated supporting load banks, the ALC3000 series intelligent programmable medium frequency power source is engineered for R&D testing, factory burn-in, maintenance and calibration of special equipment including airborne units, ground power supplies, radar navigation systems and aerospace electronics. The integrated system fully simulates real-world 400Hz aviation power supply conditions and delivers one-stop verification of power supply steady-state, transient and full-load performance. It serves as the standard core testing equipment for research institutes, aviation manufacturers and military aircraft maintenance facilities.
The ALC3000 mainframe adopts digital SPWM sinusoidal pulse width modulation and instantaneous dual-loop control technology. It outputs standard 115V/200V, 400Hz medium frequency waveforms with high-precision adjustable frequency, voltage and phase. Independent three-phase closed-loop control accommodates both balanced and unbalanced aviation non-linear loads. It features low waveform distortion and millisecond-level response speed; voltage regulation accuracy is maintained within ±1% during sudden load switching. Equipped with modular IGBT power modules, the unit operates quietly with reliable heat dissipation. Multiple hardware protections against overvoltage, overcurrent, phase loss, short circuit and overheating ensure trouble-free long-duration continuous testing, complying with strict military continuous test standards. Built with a touchscreen intelligent programming system preloaded with 30 custom test sequences, the main unit supports slow ramp-up/down of voltage & frequency, stepped output and fault waveform simulation. Standard RS232 and RS485 communication ports enable linkage with the load bank host computer to build fully automatic unattended test platforms, effectively cutting manual errors and boosting mass inspection efficiency.
The dedicated supporting 400Hz medium frequency load bank acts as a core auxiliary component of the system. Constructed with high-precision alloy resistors and premium non-inductive inductors & capacitors, it allows seamless switching between resistive, inductive, capacitive and composite RLC loads. Power factor is continuously adjustable from 0.6 to 1, with a minimum loading resolution of 1W, accurately replicating complex power consumption profiles of airborne motors, radar and communication devices. Supporting constant-power, constant-current and constant-resistance loading modes, it simulates abrupt load changes and periodic cyclic shock conditions. It captures critical parameters of medium frequency power sources such as transient voltage drop, frequency fluctuation and recovery time, and collects full-range electrical data including voltage, current, active/reactive power, harmonics and power factor in real time. Test curves are automatically saved and standardized test reports exported with fully traceable data, meeting national military standards for aviation power supply testing.
The integrated ALC3000 power source and load bank solution features synchronized coordinated programmable control. The main unit and load operate under unified timing linkage; full burn-in test sequences can be launched with one click without manual step-by-step adjustment. The load bank adopts forced air cooling and a high-protection cabinet, suitable for laboratories, hangars and outdoor maintenance stations. Modular power units simplify capacity expansion and servicing, and multiple load banks can be paralleled to satisfy high-power testing requirements. Compared with traditional separate test equipment, this integrated system offers superior compatibility, simplified wiring and eliminated signal interference, greatly lowering setup difficulty and shortening project test cycles.
Typical applications cover factory inspection of civil aircraft ground GPU power supplies, reliability burn-in of military airborne power systems, full avionics testing for helicopters, calibration of 400Hz radar navigation power supplies, R&D validation of aerospace auxiliary equipment, and routine inspection of power supplies at airport maintenance stations. Designed to meet both high-precision lab research and mass production burn-in demands, its digital intelligent programming lowers operation barriers for users, while a comprehensive safety protection system safeguards high-voltage medium frequency testing operations. Built on a proven modular framework, single-phase, three-phase, low and high-power versions can be customized according to client power demands. Integrated hardware and software measurement & control software is provided for automatic production line integration. Delivering stable, precise and efficient all-in-one testing support for aviation and military special power supply inspection, it is the preferred complete set of equipment for verifying 400Hz medium frequency power supply performance.
