Cooling fan: 12V computer case fan, standard interface, direct use Basic description: This circuit uses TDA2003 domestic integrated block, the circuit is simple, the passband is wide, the sound quality is beautiful, exclusive optimization, ultra-quiet, no impact, and can be widely used in various audio and small and medium power audio equipment, audio amplifier circuits, etc. It has the characteristics of small size, high output power, low distortion, etc. The chip has its own internal protection circuit, few external components, high output power, and adopts a small package (TO-220), which can increase the assembly density, and the switch machine has no impact and will not It damages the horn and contains various protection circuits, so it works stably and reliably. The power amplifier module has low power consumption and large enough output sound. It uses ordinary full-range speakers and has a 3P fan interface. You can directly use computer fans and support fan cascade. Use it to DIY refit as the power amplifier part of home active speakers or A small power amplifier couldn`t be more suitable.
PCB size: 84mmx80mm Radiator size: 76mmx45mmx21mm Power supply: AC and DC dual purpose, either ordinary direct current DC power supply or ordinary transformer AC AC power supply can be used. Remember! Can not be mixed, only one power supply can be connected, it is recommended to use DC12V DC power supply DC power supply: 12V2A AC power supply: 7V-11V (20W-30W transformer) Speaker unit: 3 inches-5 inches Speaker impedance: 2¥Ø-4¥Ø Material:plastic colour:Blue
Package Contents: 1 x Amplifier board
Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
