As an experienced electronics manufacturing service provider. We focus on the manufacture of variable frequency drive(VFD)circuit boards, through product processes such as component procurement, design, assembly and testing, to provide high efficiency, high quality and high standard products. You will receive first-class service and support from TECOO. You'll appreciate our unique ability to build your custom electronics quickly, reliably, and securely - all while helping reduce your time-to-market.

Variable frequency drive (VFD)circuit board parameters

-Control mode:V/F control;Sensorless vector control

-Speed control accuracy:≤±0.5% of rating synchronous speed

-Frequency precision:Digital setting: max frequency x± 0.01%

                                    Analog setting: max frequency x± 0.2%

-Interior PID controller:Be convenient to make closed-loop system

-Automatic energy save running:Optimize V/F curve automatically based on the load to realize power save running

-Automatic voltage regulation (AVR):Can keep constant output voltage when power source voltage varies.

-Automatic current limiting:Limit running current automatically to avoid frequent over-current which will cause trip

-Temperature:–10℃~ +40℃; VFD will be derated if ambient temperature exceed 40℃; each rise 1℃, the derate will be 5%

-Humidity:5%-95%, without condensation

-Impingement and oscillation:Normal running:<5.9m/s2 (0.6g); Transportation:<15m/s2 (1.5g)

-Store environment:–20℃~ +60℃; no dust, no corrosive gas, no direct sunlight

 

Variable frequency drive(VFD) circuit board features

1. Powerful function, small size, stable performance and high cost performance

2. It can be controlled separately, with high control precision

3. The integrated fault recording function allows you to debug the variable frequency drive more quickly and conveniently.

4. LED indicators show running, stop and fault status.

5. Adopt frequency hopping control to prevent mechanical resonance and make the system more stable and reliable.
