Profile:

The KDWJF-30kW is a high-performance variable frequency power supply designed for electrical testing. It delivers a standard sine wave output with low partial discharge (<5pC) and excellent stability, making it ideal for high-voltage insulation and partial discharge tests. With a wide frequency range (30~300Hz) and parallel operation capability, it provides reliable power for complex testing scenarios.

Features:

  • Low partial discharge: <5pC, ensuring accurate partial discharge test results
  • Standard sine wave output: THD <1%, voltage stability <1%
  • Wide parameter range: 0~350V adjustable voltage, 30~300Hz adjustable frequency
  • High power capacity: 30kW active power, 85.7A rated output current
  • Parallel operation: Can connect multiple units to increase output capacity
  • Strong anti-interference: High magnetic shielding, no space radiation, suitable for strong electric field environments
  • Comprehensive protection: Overload, short-circuit, and emergency stop protection
  • Low-temperature operation: Built-in heating device for normal operation down to -20°C
  • Intelligent cooling: Automatic fan speed and direction control
  • Auxiliary power supply: Isolated 220V/500W and 100V/100W outputs for test instruments
