Product Q&A

Q:What is a variable-frequency power supply?

The AC power supply from the mains is converted from AC to DC and then back to AC to output a pure sine wave. The frequency converter can simulate power grid indicators from different countries, and its output frequency and voltage are adjustable within a certain range. It can also display multiple parameters (such as voltage, frequency, current, apparent power, power factor, etc.).

Q:What is the input voltage of this variable frequency power supply?

Standard single-phase 220V / three-phase 380V. Voltages such as 110V, 120V, 460V, and 480V can be customized upon request.

Q:What output voltage and frequency can it provide?

Standard single-phase 0~300V adjustable Standard three-phase 0~520V adjustable Higher voltage output available upon request

Q:What is the rated power?

Power range from 1KVA to 200KVA, including 30KVA, 50KVA, 100KVA mainstream models.

Q:Does it have multiple safety protection functions?

Yes. Built-in overcurrent, over-temperature, short-circuit and instantaneous power failure protection.
