When a multi-voltage switching mode power supply (SMPS) from China is in operation, it itself consumes a portion of power. Therefore, its input power is greater than its output power. The efficiency of a multi-voltage SMPS from China is the ratio of its output power to its input power, that is, the efficiency of a multi-voltage SMPS from China is the output power divided by the input power. For example, if a multi-voltage SMPS from China inputs 100 watts of DC power and outputs 90 watts of AC power, then its efficiency is 90%.
Scope of application
1. Use office equipment (such as computers, fax machines, printers, scanners, etc.);
2. Use household appliances (such as game consoles, DVD players, audio equipment, video cameras, electric fans, lighting fixtures, etc.);
3. Or when it is necessary to charge batteries (such as those for mobile phones, electric shavers, digital cameras, video cameras, etc.);
Installation and usage method of multi-voltage switching power supply from China factory
Installation and usage method of multi-voltage smps factory in China
1) Place the converter switch in the OFF position, then insert the cigar head into the car's cigarette lighter socket, ensuring it is inserted properly and making good contact;
2) Ensure that all electrical appliances have a power rating below the nominal power of G-ICE before use. Plug the 220V plug of the appliance directly into the 220V socket on one end of the converter, and ensure that the total power of all connected appliances in both sockets remains within the nominal power of G-ICE;
3) Turn on the converter switch, and if the green indicator light is on, it indicates that it is working normally.
4) When the red indicator light is on, it indicates that the converter has been shut down due to overvoltage/undervoltage/overload/overtemperature.
5) In many cases, due to the limited output of the car cigarette lighter socket, the converter may alarm or shut down during normal use. At this time, simply starting the vehicle or reducing the power consumption can restore normal operation.

Precautions
1) When televisions, monitors, electric motors, etc. are started, their power consumption reaches a peak. Although the converter can withstand a peak power twice its rated power, the peak power of some appliances that meet the requirements may exceed the converter's peak output power, triggering overload protection and shutting off the current. This situation may occur when multiple appliances are being powered simultaneously. In this case, you should first turn off the appliance switches, turn on the converter switch, then turn on the appliance switches one by one, and start with the appliance with the highest peak power.
2) During use, the battery voltage begins to drop. When the voltage at the DC input terminal of the converter drops to 10.4-11V, the alarm sounds. At this time, the computer or other sensitive electrical devices should be shut down promptly. If the alarm is ignored, the converter will automatically shut down when the voltage reaches 9.7-10.3V, thus preventing the battery from being over-discharged. After the power protection is shut down, the red indicator light will illuminate;
3) The vehicle should be started promptly to charge the battery, preventing battery depletion that could affect vehicle startup and battery life;
4) Despite the converter lacking an overvoltage protection function, it may still be damaged if the input voltage exceeds 16V;
5) After continuous use, the surface temperature of the shell will rise to 60℃. Ensure good air circulation, and keep objects that are susceptible to high temperatures away from it.
