FTS series :inverter with solar energy
What is conversion efficiency?
A: Since the power supply is working, some of the electrical energy is converted into heat and lost. Therefore, the power supply must minimize the loss of heat. Conversion efficiency is the percentage of output power divided by input power. The version 1.3 power supply requires a minimum conversion efficiency of 70% at full load. Version 2.0 increased the recommended conversion efficiency to 80%.
What is the principle of temperature control power supply?
Answer: The temperature control circuit is mainly realized through the thermistor. When the power supply starts to work, the fan supply voltage is 7V. When the temperature in the power supply increases, the resistance of the thermistor decreases, the voltage gradually increases, and the fan speed also increases. In this way, the temperature inside the case can be kept at a low level. In the case of very light load, the mute effect can be achieved. When the load is large, the heat dissipation can be guaranteed.
What is over power protection?
A: In addition to the rated power, there is also a data called "overload protection", which is called "OPP" in English. Overload protection means that the load of the power supply continues to rise, and when it reaches a certain point, the power supply will automatically power off, so as to avoid overcurrent damage to the power supply or other parts of the computer. The OPP value is usually about 1.3 times the rated power. Some manufacturers set the OPP too high, which is actually unsafe. There will be an interval between the rated power and OPP. For example, the rated power of the new cold drill is 300W and the OPP is 370W. Then, this area between 300-370W is a "blind zone". If you stay in this interval for too long (usually it can last for tens of seconds), it is likely to cause the power supply or other parts of the computer to burn out.
