Advantage
Frequency converter is a three-phase AC motor control device which integrates start and stop, frequency conversion, display, key setting and protection functions. Mainly used in the need to adjust the speed of the electrical equipment, can change the output voltage by changing the frequency (can change the motor speed).
To put it simply, the frequency converter has four functions, namely soft start soft stop, motor protection, energy saving, stepless speed regulation; Five core advantages: perfect protection function, fast response speed, simple and easy control line, high-precision control range, closed-loop control system; Six protection functions, including overcurrent protection, overvoltage protection, intelligent power module protection, undervoltage protection, overload protection, overheating protection.
Frequency converter has the most basic soft starting function, can realize the controlled mechanical load motor starting current from zero, the maximum value does not exceed 150% of the rated current, so as to reduce the impact of the motor driven by the frequency converter starting current on the low voltage grid and the requirements of the power supply capacity. Energy can be saved within limits.
Frequency converter can realize V/F control and vector control according to the load characteristics. It can realize constant pressure control and constant tension automatic control.

FAQ
Q: Do you supply pattern ? Is it free?
A: If the pattern is low value, we will grant the free pattern with freight collect. But for some excessive fee samples, we want to gather the pattern charge.
Q: What is your time period of payment?
A: 30% down charge earlier than producing and 70% stability charge earlier than shipping.
Q: Which charge shape you can accept?
A: T/T, Western Union, PayPal etc. We receive any handy and swift price term.
