Variable Frequency Power Supply

Welcome to the Feixiangda Variable Frequency Power Supply Product Center. This series adopts a separate (independent) structure without a power transformer, with input isolation and output isolation, featuring high-precision frequency and voltage stabilization, knob quick adjustment of voltage and frequency, and multi-parameter high-precision true RMS digital display — the ideal AC power supply device for simulating global power standards.

Core Technology:

• Circuit Mode: IGBT/SPWM pulse width modulation, using high-power IGBT modules to reduce circuit complexity, enhance stability, and lower power consumption
• Working Principle: Input AC voltage, internal AC→DC→AC conversion produces a very stable and pure sine wave, displaying voltage, frequency, current, apparent power, and power factor
• Isolation Design: Isolation transformer completely isolates mains power from the load, improving load stability and test performance

Technical Parameters:

• Input Range: 1Φ2W 220V±10% 50Hz/60Hz / 3Φ4W 380V±10% 50Hz/60Hz
• Output Range: Low range — phase voltage 0-150V, line voltage 0-260V; High range — phase voltage 0-300V, line voltage 0-520V
• Frequency Range: 47Hz-63Hz, 50Hz, 60Hz, 400Hz
• Frequency Stability: ≤±0.1%
• Load Regulation Rate: ≤±0.5% (resistive load)
• Waveform Distortion: ≤1% (tested under resistive load)
• Reaction Time: ≤2ms
• Phase Difference: 120°±2°
• Insulation Impedance: 500VDC/200MΩ
• Voltage Insulation: 1800VAC/5mA/1min
• Cooling Method: Forced fan cooling

Protection Functions: Overvoltage, overload, overcurrent, overheat, short circuit protection and alarm device

Digital Display (4-digit true RMS):

• Frequency meter: 0.1Hz resolution
• Voltage meter: 0.1V resolution
• Current meter: 0.01A resolution
• Power meter: 0.1W resolution
• Power factor meter: 0.001 resolution

Applications:
Widely used in industrial manufacturing, scientific research, home appliances, electronics, aerospace, and other fields, suitable for precision processing equipment, motors, laboratory instruments, aviation onboard equipment, and other scenarios requiring simulated global power standards and stable pure frequency conversion power supply. The unique constant current design easily starts high-starting-current loads such as motors.
