SDR Series Fully Automatic Voltage Regulator


SDR series RELAY CONTROL AC automatic voltage stabilizer , which is the leading select of the American chip by our company, uses the computer digitization procedure to Control the functional movement of the entire machine. It improved many shortcomings of the formerly simulated voltage stabilizer and made the quality of the products to be more reliable, the performance to be more stable, the function to be more formidable.

The product has the low energy consumption, the over-voltage protection, the low voltage protection, the over- current protection, the over-power protection, the over-temperature protection, the leakage protection and so on. It boasts for many kinds of protection functions integrated to one product. It also has the following functions: the selective time delay, the anti- impact, the LED multi- demonstrations, the collection energy conservation and the environmental protection etc. This is a brand-new concept product which possess many new technologies! This series products simultaneously has applied for many technical monopolies.

1. The voltage of network input must conform to the demand of AVR, for optimum operation.

2. Connect all plugs securely.

3. Always turn AVR power switch on first, the turn appliance power switch on.(Failure to do so may cause AVR fuse to blow)

4. For best results, do not use if overload condition exists.

5. Do not use in overly humid or flammable surroudings; avoid contact with any liquids.

6. The relationship between the output capacity and input voltage as following picture and diagram:
