Project Description

The LD6402D DC power supply is specialized designed for laboratory, school and production line. The output voltage can continuously be regulated from 0 to nominal voltage value. So is the output load current. The stability and ripple factor of the power supply are suitable. Also it has prefect overload protecting circuit. It can act as both voltage regulation power supply and current regulation power supply.
