High-precision control :

      The accuracy of voltage and current is high, capable of precisely controlling the output values of voltage and current. The precision can typically reach a high level. For example, the voltage accuracy of some programmable AC power supplies can be controlled within ± (0.1% ~ 0.5)%, and the current accuracy can also maintain a similar high-precision range, meeting the stringent testing and experimental requirements for  power parameters.

      The frequency accuracy is high, enabling accurate setting and stable output of the AC power frequency. With high frequency precision, it can simulate the power grid frequencies of different regions, providing an accurate power environment for performance testing of electronic devices under various frequency conditions.

Versatility:

       Rich protection functions: It has multiple protection mechanisms such as over-current protection, over-voltage protection, over-temperature protection, and short-circuit protection. When the output current or voltage exceeds the set value, or when the internal temperature of the power supply is too high, or in the event of a short circuit or other abnormal conditions, it can automatically cut off the output or take corresponding protective measures to protect the safety of the tested equipment and the power supply itself. 

       Remote control capability: It is usually equipped with communication interfaces such as RS232, USB, GPIB, Ethernet, etc., supporting remote control and monitoring. Users can send instructions through a computer or other external devices to perform remote operations and parameter settings on the power supply, facilitating automated testing and integration into automated testing systems.
