Frequency conversion power supply, frequency conversion regulated power supply

Adopts a separated (stand-alone) design without a power transformer structure, with non-isolated input and isolated output. High-precision stable frequency and voltage, knob-type rapid adjustment of voltage and frequency. High-precision true RMS digital meter display: three-phase voltage, three-phase current, three-phase active power, frequency, with high accuracy and strong anti-interference capability. Capable of simulating upper and lower limit voltage settings: +10% to +25% / -10% to -30%. Fast transient response, with voltage stabilization response time within 2ms for 100% load/load removal. Output frequency: 50Hz, 60Hz, 45–65Hz (400Hz option). Output voltage: phase voltage 0–300V (line voltage 0–520V), capable of simulating voltages worldwide. Phase difference: 120° ± 2°. Equipped with multiple protection and alarm functions such as over-voltage, over-current, overload, and over-temperature protection.
