FAQ

Q1: Does digital voltage regulator require additional heat dissipation device?

When operating normally within the rated power range, there is no need to install additional heat dissipation devices; when used under long-term full load, high load, or in a closed and high-temperature environment, it is recommended to use it with a heat sink or a small cooling fan, which can further improve stability and service life.

Q2: What should I do when the digital voltage regulator displays abnormally?

When a display abnormality occurs, first check whether the power input is stable and whether the terminal blocks are secure. Focus on checking whether the trigger signal line is reversely connected or loose. If the wiring is normal, you can try to restore the factory settings. If the problem is still not solved, please contact our technical support.
