500W+500W Digital Power Amplifier Board Stereo Power Amp Board with Switching Power Supply
Features:
1. Size: 270 x 130 x 50mm/10.6 x 5.1 x 2" (LxWxH).
2. RMS effective power 500W+500W, 4 ohm speaker.
3. RMS effective power 250W+250W, 8 ohm speaker.
4. The bridge load can only be 8 ohms; Bridge RMS effective power 1000W, 8 ohm speaker.
5. The total peak power is 20000W.
6. The default power supply is AC220V-240V. The K1 short circuit of the power supply part can be changed to 110V-120VD for operation.
7. With temperature, power overload, loudspeaker short circuit and output DC protection
8. With DC 24V output interface for DC fan. Because the power amplifier has a large power and heats up without load, it must be added with a fan. The components also generate heat, and the fan blows air from the power amplifier part to the power supply part, not only blowing the heat sink, but also blowing to the transformer, output inductor and other heating components.
9. Auxiliary power supply +15V, 0 and -15V output. Output current 1A can be used for a preamp board.
10. With voltage limiting circuit. Two red LEDs represent voltage limiting to prevent sound overload distortion.
11. The three-pin header (L, G and R) is the signal input.
12. The five-pin socket (including G and S) and the L left channel input are connected in a direct way.
13. SW1 bridge input and stereo input conversion. Only the L left channel can be bridged. The amplifier bridges the output 8-ohm speaker to SPK1+ and SPK2+ ports.
Package Included:
- 1 x Amplifier Board
