L50 500W 8 ohm Full Bridge Mono Front and Rear Combined Finished Amplifier Board

Description: L50 500W 8 ohm Full Bridge Mono Front and Rear Combined Finished Amplifier Board Product parameters: Support mono 500-1000W 8 ohm full bridge amplifier. The maximum output voltage + -100V sine wave. L50 professional amplifier. Front and rear combined power amplifier, integrated speaker DC protection. It adopts a full-bridge output structure, which can also be called a fully balanced or bridged BTL output structure. L50 can truly output + -100V sine wave. Only the power amplifier that outputs + -100V sine wave can be called a 500W 8 ohm power amplifier. Because it uses the field effect tube HEXFET to output in parallel, its current output capability is particularly large, which is equivalent to several pairs of transistors. So it can work at 1000W 4 ohms. Of course, this requires a radiator of at least 3KG per channel. And an AC36-0-36 transformer above 1200VA. The L50 uses a full-bridge output, so under the +-50V power supply voltage, the power is the same as the +-100V power supply half-bridge amplifier. L50 uses four pairs of IRFP140N and IRFP9140N produced by IR. IRFP140N parameters: output current 33A, impedance: 0.052 ohms, 140W IRFP9140N parameters: output current 23A, impedance 0.117 ohm, 140W. Output Power: 500W 8R 1000W 4R mono, power supply voltage +-50V DC, plus AC12-0-12. 400W 8R, 800W 4R mono, supply voltage + -45V DC, plus AC12-0-12. 300W 8R, 600W 4R mono, power supply voltage + -38V DC, plus AC12-0-12. Voltage gain:200 Input sensitivity: 0.5V, output + -100V. Noise value <25MV Distortion <0.02% 1k hz, 500w, 8 ohm. Maximum output current>20A. The efficiency of the power amplifier is >60%, and the efficiency is 10% higher than that of the half-bridge amplifier. Working status of the protection circuit: The power-on delay is about 3 seconds, and the LED flashes at this time. After the detection of no DC output is normal, the relay is connected and the LED is always on. If a fault occurs during use, the relay is disconnected and the LED flashes.
