TDA1521 is a dual-channel audio power amplifier integrated circuit, 9-pin single in-line package, output power 2 × 15W. The performance is stable and the sound quality is also good, which is more common in audio applications. TDA1521 can work in single power supply or dual power supply mode, working power supply voltage range 15V ~ 40V (± 7.5-± 20V), the following is the circuit diagram of TDA1521 single power supply connection and dual power supply connection:
Figure 1 TDA1521 single power connection 
Figure 2 TDA1521 dual power connection 
When conditions permit, it is recommended to use dual power supply operating mode, so that the output coupling capacitor (OCL circuit) of the connected speaker can be removed to improve the frequency response.
[KILLING BACTERIAL]With the design of UV light and Ozone synchronize working, Uv Germicidal Lamp is laboratory tested of killing most bacterial in space of 50-320 cuft.
[TIMING FUNCTION]Combined with timing devices, you can set the Uv Germicidal Lamp turn off automatic after 15Min/30Min/60Min. Just go to work/study/walk, don't need to worry about the working Uv Germicidal Lamp.
[BIG AREA]Powerful 38 Watt UVC light, effectively covers up to 40 Square meter. Purifying no dead angle, clean distemper tiny more thoroughly.
[EXCELLENT MATERIAL] Made of quartz material, long service life, high UV transmission rate and better cleaning effect.
[ATTENTION]Ultraviolet radiation can cause skin and eye burns. Avoid direct exposure of a long time on the human body. It require people and animals waiting outside during disinfection .
What bacteria can be killed by Uv Germicidal Lamp?
UVC light is part of the ultraviolet light spectrum and emits a high frequency of UV light that makes it extremely effective at killing bacteria, viruses, mold and other pathogens. Killing bacteria with UV light requires the use of germicidal wavelengths of 185-254 nanometers (nm).
How effective is Uv Germicidal Lamp?
The use of UV sterilization, or ultraviolet germicidal irradiation, has been found to be extremely effective. Sources of UV sterilization can kill over 99% of viruses, bacteria, and fungi in an extremely short amount of time.
How does Uv Germicidal Lamp work?
How UV Disinfection Works. Unlike chemical approaches to water disinfection, UV provides rapid, effective inactivation of microorganisms through a physical process. When bacteria, viruses and protozoa are exposed to the germicidal wavelengths of UV light, they are rendered incapable of reproducing and infecting.
