The color or brand of the components will be different at different times, but the guarantee is the same. Name: High power power soft start circuit board Relay: RGL high power super large current 100A pure copper foot relay Size: 95mmX58mmX30mm (height), ultra-small size Scope of application: Suitable for high-end audio Speaker power input, . The power used is suitable within 3800W. Long-term load working power is recommended at around 2000W 110V version : Power Supply Voltage Adaptation Range: AC 100V to 125V. 220V version Power supply voltage adaptation range: AC 200V to 275V. Main Feature: The soft starter function is to reduce the inrush current at the moment of startup to reduce the impact of the machine on the grid and extend the life of the switch. This board uses ultra-high current (100A) pure copper foot relay and 4 large thermistor NTC 20D-20, which effectively protects the machine and prevents excessive starting current. This board does not require an auxiliary power supply. It has only 2 terminals, one is connected to the power input (before a switch control), and one output is connected to the load, which is very convenient to use. Working Principle: At the initial stage of power-on, the load is supplied through a thermistor with a negative temperature coefficient. As the temperature of the thermistor rises, the resistance decreases and the voltage rises slowly, thereby effectively su
