220v 60hz to 380v 50hz frequency converter

220v 60hz to 380v 50hz frequency converter

220v 60hz to 380v 50hz frequency conveter
input: single phase 220v 60hz
output: 3 phase 380v 50hz
50hz to 60hz, 50hz to 400hz, 60hz to 50hz, 60hz to 400hz, etc

Variable Voltage and Frequency Converters take the electrical input power at one frequency and voltage and provide an adjustable output voltage and frequency - ideal for testing loads over their full voltage and frequency range.

Suitable for use with Resistive, Capacitive, Inductive and Non-Linear Loads, it is able to replicate all the numerous single and three phase utility mains voltages and frequencies deployed thoughout the world.

They are not only different from frequency controller (frequency inverter) which used for adjusting motor speed , but also ordinary AC power supply. Ideal AC power supply is characterized by stable frequency, stable voltage, zero internal resistance, and pure sine wave voltage (distortionless).

They are very similar with the ideal AC power supply, therefore, more and more developed countries use it as the standard power supply in order to provide the best power supply situation for electrical equipment and test their technical performance. Ideal for use in Testing Centres, Research Labs and Testing on Production Lines.
