Sell ❂❂High power amplifier switching power supply board amplifier positive and negative 40V output can b best price

Amplifier switching power supply, positive and negative 40V output can be connected to Class A amplifiers, such as PASSA3, A5, with short-circuit overcurrent protection, and midpoint voltage protection of the amplifier, which can save the speaker protection board, and the midpoint voltage of the amplifier abnormally shuts down the output voltage . The circuit structure is 3525 push IR2110, the switch uses 50A IRG4PC50W, not the cheap solution of Taobao's IR2153 or IR2155 to directly push the field tube, we must know that the driving ability of the IR2155 is very weak, only drive A tube of about 10A, such as a small current tube such as IRF740, but for a field tube with a large current of tens of amps, it is powerless because of the large input capacitance.
