3. Protection Functions
① Over-load protection: when the actual load is higher than the rated capacity, stabilizer would power off automatically.
② Over-voltage protection: if the output voltage is 10% higher than the rated output voltage, the stabilizer stops working automatically.
③ Over-current protection: this protection function is the same as the first one, over-load protection. If the load is over rated one, the current would be higher than the rated one too.
④ Short-circuit protection: if there is a short circuit, the stabilizer would also cut off the power automatically to protect the electrical machine.
⑤ Time delay protection: there is a five-second time delay when the stabilizer powers on in order to protect the stabilizer itself.
4. More pictures
This picture shows the inner parts of the contactless AVR voltage stabilizer. Please have a look at the silicon-controlled modules and the circuit boards. These parts are very crucial to the stabilizer.
This picture mainly shows the other side, from which you could see the transformers which controls the output precision. Normally, there are six transformers for a stabilizer. Here, there are nine transformers, for which the precision of this stabilizer could be up to ±1%.
