Frequency Inverter for Large Fan and Pump

Features:

1. Takes DSP as the core, Dual CPU ControlIncluding the keypad CPU control

2. Low frequency (1Hz) large output torque.

3. Great overload capacity. 200% of rated current transiently

4.10 digital input channel, 3 analog input channel, can accept 0~10V, 0~5V and 4~20mA input signal.

5.2 pulse input channel (maximum 50 KHz), 2 OC digital output channel and 1 hi-speed pulse

Output channel are available.

6. Two 0~10V voltage and two 4~20mA current analog quantum output channel.

7. Output channel can be connected to standard secondary meter

8.16 (maximum) section speed control

9. RS485 interface as standard part

10. Remote keypad can be as long as 1000 meters off the inverter.

Advantages of Control System

1. Cheap, reliable and durable, high cost performance
2. Wide Speed range, high precision, can realize smooth infinite speed variation
3. Start impulse current start small, reducing the grid shock.
4. The built-in multiple V/F curve is adjustable, and Set user-defined V/F curve values according to the scene, better energy-saving effect.
5. The built-in PID adjustor, can easily constitute a closed-loop control system, and perfectly realize constant control to Pressure and flow. Fast response.
6. Frequency converter not only keeps structure simple and maintenance convenient as the original motor, and achieves significant energy-saving effect.
7. Debug simply, just connect correctly according to electrical diagram we provide, set a few parameters. Then turn on, run normally.
