Cool open 50U2 through U disk / SD card installed sofa housekeeper, this tutorial applies to Cool open 50U2 and other similar models;
[Installation process]
1 Download the sofa butler installation package to the U disk → 2U disk to connect the TV → 3 read the U disk file → 4 to complete the installation
ã€Steps】
2. Impedance transformation function: increase the system impedance, so that the protection device can be easily matched;
3. Function of stabilizing system voltage: for example, when starting heavy load equipment, reduce the impact on system voltage;
4. Function of preventing system grounding: when single-phase grounding occurs on 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: limit the short circuit current of the system when a short circuit accident occurs on the load side.
DG (B) /BK series single-phase isolation transformer can not only change the voltage, but also electrically isolate the input winding and output winding from each other, so as to avoid the danger caused by touching electrified body (or metal parts that may be electrified due to insulation damage) and ground at the same time. In addition, the isolation transformer also has the function of restraining various inter ferences.

Watch on-demand video on smart TVs, recommend using a TV cat, watching live TV, and recommending live HDP; more interesting content, please use Tencent video TV version, Youku video TV version, etc. Fun smart TV and box, more exciting Content is on the sofa butler.
Single Phase Isolation Transformer
Generally included
Single Phase Isolation Transformer,Isolation Transformer,Auto Transformer,Single Phase Electrical Transformer
Characteristic
1. Anti interference effect: if the isolation transformer connected with Y/â–³ can prevent the transmission of some harmonics;2. Impedance transformation function: increase the system impedance, so that the protection device can be easily matched;
3. Function of stabilizing system voltage: for example, when starting heavy load equipment, reduce the impact on system voltage;
4. Function of preventing system grounding: when single-phase grounding occurs on 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: limit the short circuit current of the system when a short circuit accident occurs on the load side.
