Project Description

LD12005D digital Linear DC Power Source possesses automatic transfer function to regulate voltage and current. And its circuit is composed of compensating pipe power exhaustion steering circuit, operational amplifier and reference voltage regulator with temperature compensation. Therefore, the circuit is stable and reliable. The output power voltage of the power supply may randomly be regulated from 0 to nominal voltage value. When it is in the state of current regulation, the current regulation output current can continuously be regulated from 0 to nominal current value.

This power supply is characterized by small volume, good performance and new style, and are first choices for scientific and research institutions, colleges, factories and electrical appliance maintenance units.
