TVFE9

TVFE9

El inversor de la serie TVFE9 (variador de frecuencia) es un inversor vectorial sin sensor de velocidad de alto rendimiento desarrollado independientemente por nuestra empresa.
Cuenta con un excelente rendimiento dinámico de aceleración y desaceleración, una alta salida de par a baja velocidad (1.5 veces el par nominal a 0.5 Hz), una alta capacidad de sobrecarga y una operación flexible y conveniente. Además, ofrece control PID en direcciones directa e inversa, un tamaño compacto y una fuerte adaptación ambiental.
