Product Description

Generator  Automatic Voltage Regulator AVR 30kva Regulator R450  

Generator  Automatic Voltage Regulator AVR 30kva Regulator R450 is a half-wave phase controlled thyristor type Automatic Voltage Regulator and forms part of the excitation system for a brushless generator. In addition to regulating the generator voltage, the AVR circuitry includes under speed and sensing loss protection to ensure safe, reliable control of the generator. 

Positive voltage build up from residual levels is ensured by the use of proficient semiconductors in the power circuitry of the AVR. Which is linked with the main stator windings and the exciter field windings to offer closed loop control of the output voltage with load regulations of +/- 1.5%

Payment Terms

1.100% T/T before shipment for stock supply products; 30% as advance and balance before shipment for  production and special design order.

2. The following payment ways are acceptable.

3. Additional requirements please contact us for more information.






1. What' s mean by the model with -A, what's the difference?  

The model with -A is the same function with the original model, the difference is the -A model use the imported supper capacitor . Such as SX460-A has the same function with SX460, but SX460-A use the imported capacitor( the Red color one) and the SX460 use the domestic capacitor ( the Blue color one). They can replace each other when application. The cost of the -A model is higher than the original one.


2. Is our company a trade company or factory?

We are manufacturer, we have own factory for AVR, RECTIFIER, CONTROLLER,MOTOR AND GENERATOR SPARE PARTS. This is certified by Alibaba and our showed photos can prove it. Also we can say we are the International sales department for these products and charge all the business of these products.


3. Is our company accept customized and OEM order ?

Yes. Our factory has very professional engineer and design team to provide special customize products for you. Client only provide there requirements to us, we can design for you for free. OEM factory is acceptable too. Let our factory to be your own factory.


4. Futher more question welcome to contact us any time.
