Stamford power ac brushless Generator automatic voltage regulators avr SX460
SX460 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%

Our advantage:
| Semiconductor power devices | In NXP Chinese package |
| Main power resistors | British WELLWIN original |
| Adjusting potentiometer | U.S. BOURNS original |
| Chip capacitors | South Korea's Samsung |
| Glue | PU environmental protection, at the same time does not change the electrical properties of high-temperature and high-temperature characteristics |
| More advantages | 1.After the the strict fully functional and performance testing, and high-temperature aging, each batch of test reliability ratio of 3%. The parameters of each board are rigorously tested and adjusted, fully compatible with original products 2.High stability of the key components of the product, we use a low temperature coefficient components to ensure product 3.Original two transistor, and 2 ounces of large-current circuit board (the majority of the conventional circuit board is 1 ounce) to ensure high reliability in a high-power semiconductor element |
