China 12 years factory 75kw 304A Frequency Converter Single Phase To 3 Phase 220V To 380V VFD/Variable Frequency Drive For Motor

China 12 years factory 75kw 304A Frequency Converter Single Phase To 3 Phase 220V To 380V VFD/Variable Frequency Drive For Motor

Product Introduction:

PI500 Series Sensor-less Vector Control Frequency Inverter is a function enhanced product with strong stability. It takes use of German Infineon IGBT and the TI DSP chip set, completely optimizes vector control and V/F control. It has been widely used in various industrial environment, and special in situations requiring speed control precision pump torque response speed and low-frequency output.

Specification:

power rating:0.4-630kw

voltage:AC 1PH 220V(-15%) - 240V(+ 10%) 
               AC 3PH 220V(-15%)-· 240V(+ 10%)
               AC 3PH 380V(-15%)-440V(+ 10%) 
               AC 3PH 480V(-10%)- 480V(+ 10%)
               AC 3PH 690V(- 10%)~- 690V(+ 10%)

Output Frequency:0-400Hz

Technique Features:

1. Two control modes: V/F control, Vector controlW/O PG,Vector control W/PG
2. Starting torque: 0.5Hz/150%(Vector control W/O PG);
3. Internal brake unit has been deployed, and the braking resister can be connected outside for a quick stop;
4. Five kinds of V/F control, which are constant torque V/F curve, One kind of customer defined V/F curve, 3 kinds of down torque curve (2.0/1.7/1.2 times the power).
5. Through PLC or internal control terminal, multi-speed control and PID control could be realized. And users could combine a variety of operating modes while it’s necessary;
6. Supporting multi-frequency deploy methods: digital setup, PID setup, analog quantity setup, and communication setup;
7. Supports starting and stopping DC brake;
8. PI500 is Equipped with jump frequency control, which prevents mechanical resonance and makes the system more stable and reliable;
9. PI500 has build-in PID in order to establish close-loop control system easily;
10. PI500 is designed with the central frequency switch function, which let the end user to fix the central frequency while it is necessary;
11. PI500 has been equipped with RS485 communication interface, which support MODBUS protocol with ASCII and RTU forms;
12. Working with water supply accessory to realize multiple-pump stable constaant pressure water supply function.
