What is the primary use of a 400Hz frequency converter?
A 400Hz frequency converter is primarily used as an Aircraft Ground Power Unit (GPU) to provide stable electrical power to aircraft while they are on the ground for maintenance or pre-flight checks.
What are the benefits of using IGBT technology in this unit?
IGBT high-frequency static inverter technology allows the unit to be more efficient, significantly smaller in size, lighter in weight, and operate with much lower noise compared to traditional rotary converters.
Can the output voltage and frequency be adjusted?
Yes, both voltage and frequency can be adjusted online in real-time. The frequency range is typically adjustable between 40Hz and 499.9Hz via integrated software control.
What safety protections does the unit include?
The unit is equipped with multiple protection functions for abnormal conditions, including overvoltage, overcurrent, overload, overheating, and short-circuit protection with automatic jump and alarm devices.
Is the power unit compatible with inductive loads?
Yes, the unique double-loop control mode and SPWM technology allow the unit to adapt to various loads, including resistive, inductive, and rectifier loads.
Does the unit support three-phase power?
Yes, we offer models for both single-phase and three-phase input/output configurations to meet different industrial and aviation power requirements.
