Programmable DC power supply is a wide range of output power supply, can provide stable wide voltage and current output as required. A work equivalent to multiple traditional "rectangular" DC power supplies to meet a variety of voltage and current testing requirements, greatly helping customers save cost and space. At the same time, it has a variety of protection modes to protect the safety of the test equipment.

In practical application, short circuit protection provides dual protection for the power supply itself and the measured object. When the conventional DC supply enters CC mode and the voltage output is reduced to very small (0.7V), the DC supply will enter short circuit protection mode. At this point, the power output will be turned off, and a warning screen with a buzzer alert will appear to prompt the user's attention. But at the same time, this short-circuit protection also has limitations. When testing cables, fuses and circuit breakers, active protection of the power supply will not be achieved. To solve this problem, programmable DC power supplies introduce an ultra-low voltage mode that allows normal testing of cables, fuses, and circuit breakers, such as cable internal resistance and fuse break time.
