PWM VFD EMS103

OEMadjustableclosed-loop

TECOO, as an experienced electronic manufacturing service company, provides customers with OEM electronic manufacturing solutions for VFD control boards, our important attributes are our flexibility, production capacity, reliable delivery schedule and ability to improve processes, and we start from scratch Tracking product manufacturing through its lifecycle ensures product consistency and traceability. Our goal is to be your reliable Electronic Manufacturing Services (EMS) partner. The VFD control board is an indispensable part of the inverter, so what are the characteristics of the VFD control board? 1. Using multiple PWM control, the output voltage waveform is close to sine wave. 2. The rectification circuit is multiplied, the number of pulses is large, the power factor is high, and the input harmonics are small. 3. Direct high voltage output without output transformer. 4. Very low dv/dt output without any form of filter. 5. Some use optical fiber communication technology, which improves the anti-interference ability and reliability of the product. 6. The power unit automatically bypasses the circuit, which can realize the function of non-stop when fault occurs. 7. Controllable acceleration function, adjustable running speed, adjustable torque limit 8. High reliability, easy operation, strong versatility, easy to form closed-loop control Scope of application Mainly used in fans, pumps, plastics, woodworking machinery, textile machinery, escalators, CNC lathes, high-speed punches, ore machinery, printing machinery, electric power, building materials, coal, medicine, papermaking, urban water supply and sewage treatment industries.
