Product Description

300kVA High Precision Variable Frequency Power Supply For Industrial

The single-phase and three-phase AC variable frequency power supplies utilize SPWM (Sinusoidal Pulse Width Modulation) high-frequency pulse width modulation and advanced DDS (Direct Digital Synthesizer) technology for waveform generation, delivering a clean sinusoidal output. •  Output Frequency: 40 Hz to 500 Hz (10 Hz to 1000 Hz available upon request)  •  Output Voltage: Low range: 0-150 V / High range: 0-300 V (0-2000 VAC customizable)   These power supplies are capable of simulating both standard and abnormal voltage/frequency conditions. They are ideally suited for production and research applications in sectors such as test systems, electronic appliances, electric motors, and lighting.
