Features:
1. Delay start, the first relay is connected at the moment of power-on, and then the current is limited by the NTC thermistor. After a delay, the main relay is turned on to realize the soft-start function. Suppress the inrush current of the power amplifier, because the power of the class A and high power amplifier transformer is large, the load impedance is extremely low, and the capacity of the power supply filter capacitor is too large, resulting in excessive current of the power amplifier when the power is turned on, which easily damages the rectifier bridge and the damage filter capacitor.
2, 2 way overheat protection, use the attached 75 degree temperature control switch to install on the radiator,
When the temperature of the power amplifier board heat sink exceeds 75 degrees, the board can immediately cut off the power supply, and the power amplifier will not be overheated and burned. Until the temperature of the heat sink drops below 75 degrees, the power amplifier can be turned back on, otherwise the power amplifier can't be turned on.
3. The power switch uses a tact switch, which is convenient and flexible. To prevent frequent machine damage to the machine
After the soft-start is turned on, it takes about 12 seconds to shut down!
4. The input power supply voltage is between AC115V and AC230V.
75 degree temperature control switch
When the power amplifier board heat sink exceeds 75 degrees, the board immediately cuts off the power. The amplifier can be turned back on until the temperature of the amplifier's heat sink drops below 75 degrees.
Package includes:
1x soft start board
1xTact switch,
2x 75 degree temperature control switches,
