2000W Class AB Power Amplifier

This is the circuit diagram of 2000W class AB power amplifier uses 7 pairs MJ15003 and MJ15004 transistors for the final amplification block. The circuit operated with 90V DC symmetrical (dual polarity) power supply circuit. The transistors must be mounted on heatsink to prevent the overheating, maintain the transistors work in maximum performance.

2000W Class AB Power Amplifier Specifications:

  • Max. Output Peak Power: 2000 Watt Peak @ 2?Ohms Loudspeaker
  • Max. RMS Output RMS Power: 1000 Watt RMS @ 2?Ohms Loudspeaker
  • Max. Bridged RMS Output Power: 2000 Watt RMS @ 4?Ohms Loudspeaker
  • RMS Output Magnitude: 44.7v RMS
  • Peak Output Magnitude: 65v Peak
  • Freq. Response: 20Hz ~ 20KHz
  • Max. Output Gain: 40dB
  • Input: 100mV Peak
  • DC Power Supply: 90v DC (Dual Supply)
