VFDC-4100 Controller

1 - 4 Pump Control Applications

The VFDC-4000 Controller maintains a constant discharge pressure by adjusting the speed of 1 to 4 VFDs in pressure booster pump systems.

The VFDC-4100 is a microprocessor based controller specifically designed for constant pressure applications using 1-4 variable frequency drives.  It features P.I.D. control, automatic alternation, data logging, and communication capabilities.  A backlit graphic display allows users to monitor pressure, pump speed and alarm status.  The VFDC-4100 controller uses a menu driven setup that makes navigation and configuration fast and simple.

Aplicaciones de control para 1-4 bombas

El controlador VFDC-4000 mantiene una presión de descarga constante mediante el ajuste de la velocidad de 1 a 4 variadores de frecuencia en sistemas de bomba de aumento de presión.

El controlador VFDC-4100 es un microprocesador diseñado específicamente para aplicaciones de presión constante utilizando 1-4 unidades de variadores frecuencia variable (VFD). Cuenta con P.I.D. control, alternancia automática, registro de datos y capacidad de comunicación.

Una pantalla gráfica LED permite a los usuarios monitorear la presión, velocidad de la bomba y el estado de la alarma. El controlador VFDC-4100 utiliza menú que controla la configuración haciendo esta y la navegación más rápida y sencilla.
