1. Working voltage: AC 220V2. Regulation voltage: AC 10-220V3. Efficiency: more than 90 percent4. Power: 4000W (resistive load limit power), long time should reduce power use5. Weight: about 133.2 g6. Size: about 8.5 x 5.5 x 3.8 cm, the knob hole is about 6mmFunctional features:1. 41A thyristor, 1.6mm thick FR-4 high-temperature circuit board, circuit design is reasonable, and the use of larger and thicker welding circuit design, even if the high current through the enough to cope with the use of a more reliable2. Using the standard 3 of the 4-position terminal block, two in two out more convenient wiring, with a shell with a fuse regulator, installation is more convenient, more suitable for families and inconvenient installation of factories and enterprises3. The circuit has been improved through a number of technical improvements, the use of dual capacitor design (safety gauge capacitors + metal film capacitors), effectively absorbing surges and voltage spikes, more effective protection of the SCR, the use of more efficient and more4. External 1.5 thick aluminum and stainless steel molding stamping, beautiful and generous, more suitable for home thermostat speed control and industrial enterprises, beautiful and generous, the use of long time will not rust and other appearance problems5. 4000W voltage regulator, technology upgrades, voltage range from 10V-220V smoothly adjustable, more suitable for industrial enterprises that need low voltage to drive the heating wire, such as cutting styrofoam, pearl cotton, raincoat production and so onAttention:1. Pay attention to connect the load before regulating the voltage2. Thyristor is mainly used for resistive loads (electric filament incandescent lamps, etc.), single-phase AC motors can also be most, but does not guarantee that all can be other types of loads, please buyers to confirm their own, the fuse is not, there is a reaction time, if the current is too large, in addition to burn the fuse, the module may also burn out3. Pay attention to the plastic cover on the connector due to the installation of the shell, can not be completely lifted, the screwdriver should be biased point screwing, in addition to lift to be careful, too much force is easy to break the cover, courier transportation may also be crushed for wearing parts, but will not affect the module to use

Adaptable speaker power (30W-150): 4 ohms (8-12V power supply), 8 ohms (8-24V power supply), 16 ohms (8-24V power supply)6. Module protection mechanism: reverse power supply protection, short-circuit protection, self-recovery overheating protection7. Note: to improve the performance of the module, it is recommended to work more than 20W x 2 application scenarios under the amplifier chip plus heat dissipation8. Anti-static bag packaging, acrylic panels have a protective film, please tear off when assembling9. Module size: about 5 x 3.3 cmOperating instructions:1. After turning on the power, the blue indicator light will flash quickly to enter the Bluetooth mode2. Enter pairing mode and wait for pairing after announcing the beep3. Mobile phone bluetooth search to XY-P15W (amplifier board device name), click XY-P15W connection4. After successful connection, play the tone, the indicator light will be on, you can play the music on your cell phone, and the indicator light will flash slowly when playing the music5. Bluetooth disconnect the amplifier board to prepare for the next pairing, and play the tone after entering the pairing mode waiting for the pairingPrecautions for use:1. Amplifier board to use as far away from WIFI signals (router)2. Recommended power supply voltage DC 8-24V, more than 26V, the chip will be burned3. Connect 4 ohm speakers when the power supply does not exceed 12V, connect 8 ohm speakers when the power supply does not exceed 24V4. Recommended power supply current is more than 2A5. Module working power more than 20W x 2, need to add heat sinks6. The speaker cable should not be too long, ensure that 1 meter or less is suitable7.
