● Improved bugs that can't be started occasionally
●The control switch is changed from the original single tact switch to self-reset and self-locking. The default is from the reset type when shipping. If you need to purchase the self-locking type, please specify (self-locking type, temperature). The protection function is invalid).
● What is a self-resetting switch and what is a self-locking switch?
● A: Your home doorbell switch is a self-reset switch. Press to turn it on and release it to disconnect. Your home light switch is a self-locking switch.
●Main parameters:
● PCB board is 2MM high-grade fiberglass board
●The copper foil of the PCB is 2 ounces
●The size of the PCB is 77.5MM*92MM.
●The distance of four symmetric holes is 69X83.5MM
●The product weight is 230g
●The rated current of the relay is 30A, which can withstand the power below 1000W.
●Main features:
● Suppress the inrush current of the power amplifier at startup, 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, which leads to excessive current at the startup of the power amplifier, which easily damages the rectifier bridge and damage filter capacitor.
● When the temperature of the heat sink of the power amplifier board exceeds 75 degrees, the board can cut off the power immediately, 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.
