size:
application:
Advantage：
1、Innovative SMPS circuit, to achieve very low power consumption and a wide range of power supply operation.
2、Innovative Operational Fault Protection, which adaptively maintains the normal operation of the system by actively detecting the output power from the power supply.
3、Real-time measurement and processing of output signals to obtain real-time instantaneous output power: compare all data wells with the effective storage energy and effective power obtained from the power supply to avoid system deviation, such as overvoltage, overcurrent, short circuit, etc.
4、 Harmful Signal Protection: DC protection, VHF protection, clipping protection.
5、Power, light weight, beautiful sound, is widely used in a variety of touring shows, bars, disco, high-end nightclubs, is the first choice for first-class system designers, audio engineers.
