Industrial control transformers .
Conventional rated input voltage: 440V / 380V / 220V. Special input voltage requirements can be designed and produced according to user requirements;
2. Conventional rated output voltage: the control transformer has 110V / 127V / 220V;
The lighting transformer has 34V / 36V;
The signal control transformer has 6V / 12V, etc
Industrial control transformers
The ambient air temperature is – 5 ° C to + 40 ° C, and the average value in 24 hours does not exceed + 35 ° C;
The sea level of the installation site shall not exceed 200m;

characteristic
1. Anti interference effect: for example, after passing through the isolation transformer with Y / â–³ wiring, it can prevent the transmission of some harmonics;
2. Impedance transformation function: increase the system impedance to make it easy for the protection devices to cooperate;
3. Function of stabilizing system voltage: such as reducing the impact on system voltage when starting heavy load equipment;
4. Function of preventing system grounding: when single-phase grounding occurs at the load side of the isolation transformer, it will not cause single-phase grounding of the whole system (above the satons isolation transformer);
5. Reduce short-circuit current: when a short-circuit accident occurs at the load side, limit the short-circuit current of the system.
