OEM JK-1KVA AC Transformer Step Up Transformer 12v DC To 240v AC 220v 12v ac transformer
1.Application:
full automatic AC voltage regulator is one of the leading products of our company. Their structure is composed of the contact type auto-former regulator, servo electric motor, automatic control circuit and so on. When the electrical network voltage is unstable or the load is changed, it will automatically sampling control circuit and send out the signal to drive servo electric motor, adjust the carbon brush position of auto-former regulator so as to make the output voltage to be the rated value and be the steady state.
There are lots of merits of our company's voltage regulator such as various varieties, complete specification, and beautiful appearance. And it also has characteristics of started waveform, reliable performance, long-term movement and so on, and it is equipped with the time delay, over-voltage, and under voltage protection function and can widely be used in many electricity place, is one kind of ideal voltage-stabilized source that can keep your equipment on.

3.Working conditions:
1. Ambient air temperature: -5 degree ~+45 degree, the highest monthly mean temperature should not exceed +30°C;
2. Altitude for installing place should not exceed 2000m;
3. When the ambient air temperature is +40°C, the relative humidity should not exceed 50% and it allows higher relative humidity under lower temperature. Max average humidity in the dampest month is 90%, meanwhile the lowest average temperature of this month is + 25°C, and condensation on the product surface caused by temperature change should be taken into consideration.
