Project Description

MD3010-2DF multiplex output is high-precision power supply composed of multiple output Power Supply and one-way fixed output power supply. It uses four groups of 4 LED to display output voltage and current values of the two way power supply respectively. In addition, two-way regulated output power supply 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.
