2. Product Performances

Protection functions Short circuit: when there is a short circuit, the stabilizer would cut off the power automatically to protect itself and the machine it connects with
Over-voltage: when the output voltage is higher than the value set, the stabilizer would react and cut off the circuit
Under-voltage: when the output voltage is lower than the value set, the stabilizer would stop working
Over-current: when the current is higher than the rated current, it would cut off the power supply automatically
Over-load: if the actual load is over the rated one, the stabilizer stops working immediately to protect the machine
Load Capability

30 seconds with 120% of its rated capacity

Working continuously with 80% of its rated capacity
Energy-saving Characteristic It is very enegy-saving. The power comsuption is only 1% of the rated power capacity

4. FAQ

① How long is the lead time?

It's generally several days if the quantity is less than 10 units. If it's more than this figure, it might takes a longer time for us to produce the products.

②What about the payment terms?

TT, L/C, are accepted. And we often quote based on the price of EXW.

③ How long is the warranty period?

It's 12 months since you buy the product.

④ How would you help us if there are some problems at spot when we use the product?

Firstly, we would respond within 48 hours due to the time lag between different countries. Then, we would analyse the real situations and put forward some solutions. Third, if you still can not solve the problem, we would guide you through video calling or other social media to solve the problem.
