Product Details
1.Description:
The circuit is a standard circuit, stable and reliable.
The filtering adopts a voltage withstand voltage of 50V and a capacity of 2200uf large electrolysis.
Power supply voltage: dual 12-36V ring cattle, recommended to use dual 32V ring cattle
Output power: 85Wx1 undistorted rated power, peak power 100W
Can easily push speakers of over 100W
2.Parameter:
1>.Work Voltage: AC12-36V
2>.Output power: Max 100W
3>.Speaker impedance: 4-8 ohm
4>.Work Temperature:-25℃~85℃
5>.Work Humidity:5%~95%RH
6>.Size: 50 x 50mm
3.Note：
1>.This version already includes rectification and filtering circuits, so it is necessary to use a 3-wire transformer. Dual AC 12-32V can be used, and DC power cannot be supplied. If installed, it will burn
2>.The chip generates a significant amount of heat, and in any case, a sufficiently large heat sink must be installed when powered on.
3>.The chip must be insulated from the heat sink, otherwise it will burn out.
4>.Using a standard ring transformer as the power source is a good choice, and adjustable power sources cannot be used.
5>.All wiring should not be reversed or connected incorrectly, otherwise the chip will be burned.
6>.There are positive and negative pins of electrolytic capacitor and diode, which cannot be reversed.
7>.This product is single channel, to make dual channels, you need to purchase two sets.
