TDA7293 Dual Parallel 170W Mono BTL Audio Power Amplifier AMP Board Assembled

Specification:

IC board is brand new original authentic，This product is welded, tested good finished board. This circuit is a

channel without a rectifier circuit, if you want stereo, please buy two pieces.

Power supply: 15V AC double to 28V (AC needs rectification filter) or ± 18V dc to 40V. 

Recommeded Power supply: 15V AC double to 28V (AC needs rectification filter) or ± 18V dc to 40V. Recommended dual

35V, 35V transformer attention not double, plus or minus 35V DC (recommended dual 26V / 200W or more
toroidal transformer, the transformer output must be three lines, such as:
26V­0­26V, (referred to as dual 26V) dual DC rectified voltage of about 35V), the transformer output is two
lines or four lines is not possible.
Reminder: the battery can be used! (Must be connected in series battery).
Transformer power: Minimum 200w, multi­channel power is calculated separately to note that the better must
be truly full power transformer
Output Power: Maximum power output 170W, than the rated power, output power and output transformers
and speaker proportional
Load: 6­8 impedance around Europe 100w­150w box is very suitable, we must choose a good speaker
problem
Board dimensions: length 70mm width 35mm height 25mm <height of containing the chip installed height>
Weight: 40g (5g within error).
Audible Noise: None
The board without any noise, the premise is to deal with the ground and the level audio to the noise
Midpoint voltage: less than 5mV
BTL perfect support multiple board connection
Board are pure amplification stage
Board only supports DC input rectifier filter section without a friend in need can additionally choose
We must ensure that the positive and negative at the same time and the positive and negative supply voltage
error can not exceed 1v.
Integrated chip TDA7293 must be insulated from the heat sink a hundred percent.
