12-24V 170W + TDA8950 digital power amplifier board 2.0-channel car | Электроника

The TDA8950 amplifier board with digital amplifier chip as the core, the chip efficiency can reach more than 90 percent, with a small, efficient, power and other characteristics, with the professional car booster circuit with low voltage power supply, high power output characteristics. Amplifier board can take a two-channel modes OCL or BTL bridged mono, OCL mode output 170WX2, BTL mode output 300Wx1, it can easily compose 2.1 amplifier system. In the selection of elements, which by no means stingy, but not extravagant, choose the right, the right to improve the board's price. Capacitance aspects such as: red ring large current digital amplifier dedicated inductor ruby, King Kong, Philips, Siemens and other fever capacitance, output terminal, sealed high-quality potentiometer, original TDA8950 chip manufacturers original SMD chip devices, and so on. Select the sophisticated design, high-quality components, making it capable of long-term stability.
 
With: The amplifier board can use as a pure power amplifier only need to connect to a large battery, you should not use the 12V small switching power supply, otherwise it will seriously damage the power, you can use with the tone board, or boards made with a low-pass subwoofer amplifier board, the cost is very high
 
Features:
1: Excerpts differential inputs can be selected, the effect is even better, you need to balance the output of the preceding stage is to pick oh
2: The board comes with rectifier filter circuit, eliminating the trouble himself with rectifier filter, using 30A rectifier bridge with a new original Korea
   And three high-speed electrolysis array, the effect is very good
3: comes with speaker protection circuit, installed substitution DIY easier
4: The above reserve position potentiometer,
5: easy access to BTL output, the time of purchase and the buyer needs to contact
6: control with ACC, ACC then high work
 
Operating voltage: DC12-14V (be careful not to use a small switching power supply, must use battery)
Maximum output: OCL = 170Wx2 BTL = 300Wx1
Board size of about: 125mm / width 100mm high 40MM (Dimensions excluding potentiometer handle and other protruding parts)
Package of accessories: test a good amplifier boards, including fins, 3PIN a shielded cable
    Please received prevail in kind oh. Because different batches, the fins are different colors. Mind carefully shot.
