2. Suitable for all kinds of Class A or high power amplifiers, the maximum power is 2000W.
3. 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, 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.
4. When the heat sink temperature 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.
Parameters:
Voltage: 110V or 220V (110V or 220V can be selected)
Board size : 78*87*32
(According to the input voltage, select the voltage of PP+ input. For example: input 220V, that is PP and
220V soldered together, pay attention to PP can not be connected at the same time 110V and 220V) factory default is 220V
