Listed at 33.65 USD. YJ00311-Amplifier power supply delay soft start temperature protection board Class A Power Supply Delayed Soft Start Temperature Protection Board Introduction: 1.PCB adopts 1.6mm thick double-sided plate, 2.0 ounce copper thickness, spray tin full process, to ensure that the size of the current through a good. High performance PCB quality production process. 2. Suitable for a variety of Class A or high-power amplifiers, power 2000W. 3. Suppresses the instantaneous inrush current of the amplifier. Due to the high power of Class A and high power amplifier transformer power, load impedance is particularly low and the power supply filter capacitor capacity is very large, which leads to instantaneous high current of the amplifier, and it is very easy to damage the rectifier bridge and damage the filter capacitor. It is very easy to damage the rectifier bridge and the filter capacitor. 4. When the temperature of the radiator of the amplifier board exceeds 75 degrees, the board can immediately cut off the power supply, so that the amplifier will not be burned by the heat. Until the radiator temperature drops below 75 degrees, the amplifier can be rebooted, otherwise the amplifier will not power on. Parameters: Voltage: 110V or 220V (can choose 110V or 220V) Board size ： 78*87*32mm According to the size of the input voltage, select the voltage of PP+ input. Such as: input 220V, that is, PP and 220V welded together, note that PP can not be connected to 110V and 220V at the same time. Factory default is 220V Package: 1pc amplifier power supply delay soft start temperature protection board
