## Overview

The VOLTEQ HY3003D-3 is a high-precision linear DC power supply featuring triple outputs: two fully adjustable 0-30V/3A channels and one fixed 5V/3A output. Its 10-turn potentiometers allow fine voltage control, while flexible output modes (independent, series, parallel) deliver up to 60V or 6A. Bright LED displays provide accurate voltage and current readouts, supported by tight line and load regulation and comprehensive protection mechanisms, making it ideal for demanding professional and lab environments.

## Description

VOLTEQ HY3003D-3 is a triple output variable regulated linear DC power supply. This linear power supply has three outputs: two outputs are continuously adjustable at 0-30V DC and 0-3A, and the third output is fixed at 5V DC and 3A. What's more, the two outputs can be used either in independent, series or parallel mode, providing either two independent outputs, or one output with twice the voltage or twice the current output, up to 60V or 6A. The unit comes with 4 bright LED displays, providing accurate readout for the voltage and current value for both outputs. The voltage knobs have 10-turn pots, so it's real easy to control the outputs. Comes with two connectors for series or parallel mode. Please email me with any questions!
