XC5050 type programmable audio power supplyDetailed product description：

The XC5050 programmable audio power supply is a supporting power supply for the highest level XF12 audio power standard device in China. It can also be independently used as a testing power supply for high-precision measurement of other instruments and meters. It is an ideal upgraded product for analog audio power supplies. This audio power supply adopts a fully digital synthesis signal source, and the true effective value closed-loop feedback method significantly reduces the impact of load on output stability. The application of the power module is to significantly reduce the size of the device. The unique amplitude adjustment modes of fast, medium, and slow, as well as the bidirectional communication display control function between the external control keyboard and the host, conform to the operating habits of meter detection and are conducive to improving work efficiency. In addition, this device provides a digital interface that can be easily integrated with other standard testing instruments to form an automated testing system. Due to its high stability and long-term drift, the XC5050 audio power supply is widely used in metrology institutes, power systems, and enterprise metrology units in various provinces and cities across the country.
