Digital Voltage Regulator - China

price: contact company for price

I. Product Introduction

Digital voltage regulator includes digital single- phase voltage regulator and digital three- phase voltage regulator, as an AC voltage regulator, it adopts an integrated design combining digital three- phase power controller and load- matching transformer and it realizes the continuous regulation of output AC power by the way of phase shift & voltage regulation at the primary side of the load- matching transformer. It has open- loop or various closed- loop control forms and multiple given control signal selections.

Digital voltage regulator realizes the matching of load power and voltage by changing the power and transformation ratio of the load- matching transformer according to the requirements of actual load power and voltage and it can be widely used in the continuous regulation and control of single- phase or three- phase AC power of automatic temperature control systems such as various industrial heating and heat treatment system etc.

II. Performance Indexes

1. It adopts cabinet- type integrated design.

2. Integrated control functions such as constant voltage, constant current and constant power closed- loop control and open- loop control, power regulation control, phase shift / power regulation control functions can be set freely.

3. With high- precision AD conversion, the constant voltage, constant current and constant power precision is higher than 0.5% and the system resolution ratio is higher than 1‰.

4. It is equipped with a LED numeral display tube, which is convenient for setting various functional parameters and displaying electrical parameters.

5. It has an automatic current- limiting function, when the output current is equal to or greater than 1.1 times of the rated current, the current will be limited.

6. It has phase- deficient, overcurrent, overheating, SCR fault, load disconnection or unbalance protection functions.

7. Fault self- diagnosis function.

8. Automatic phase- sequence confirmation function.

9. It has soft start and soft turn- off functions.

10. With RS485 communication interface and MODEBUS communication protocol, it can communicate with PLC and the host computer, which is convenient for remote monitoring.
