This series of control boxes are designed and produced based on the unique range of use of high-pressure test Transformers. Their functions include:

A, closed sound and light alarm;

B, timing sound and light alarm;

C, electronic low-voltage current protection(box type);

D, high voltage direct reading;

E, pressure test time is set freely(several signs);

F, mobile structure(desktop).

The capacity of the control box is nominal with the capacity of the regulator. If it is accompanied by a test Transformer(working system within a short time of 30 min), it can be based on the provisions of the People's Republic of China Power Industry Standard "DL474.4-92": P0 = 0.75 P selection. P0-test Transformer capacity; P-regulator capacity. If used for batch testing of electrical professional factory products, the regulator capacity should be equal to the test Transformer capacity, ie: P0 = P.
