Designed for engineering workbenches and technical development environments, the KQ7901 combines programmable output settings, list sequencing, remote sensing, and digital control capabilities. Engineers can configure output conditions, save frequently used settings, and execute predefined output sequences to support repeatable circuit evaluation and system development.

Whether developing power conversion circuits, evaluating control boards, or integrating DC-powered components into electrical systems, the KUAIQU KQ7901 offers a versatile DC power source for practical engineering work.

Key Features

1. 80V 20A 400W Adjustable DC Output

Provides adjustable DC output up to 80V and 20A, with a maximum rated power of 400W. The wide output range supports different electrical engineering projects, including DC circuit development, power supply modules, and control electronics.

2. Programmable Output for Engineering Applications

Configure output parameters to meet different circuit requirements. Programmable operation helps engineers establish repeatable power conditions when evaluating electronic components, developing electrical circuits, and refining DC system designs.

3. List Sequencing for Multi-Step Power Settings

The list sequencing function supports predefined output sequences, making it useful for engineering workflows that require multiple programmed output conditions. It can help organize step-by-step circuit evaluation and repeatable power-up procedures within the power supply's supported operating limits.

4. Remote Sensing for Improved Load-Voltage Accuracy

Remote sensing compensates for voltage drops in output leads when connected and configured correctly. This helps maintain the intended voltage at the load terminals, which is particularly useful when working with longer leads or circuits with demanding voltage requirements.

5. Digital Control and Convenient Parameter Management

Digital control capabilities support more structured operation in electrical engineering environments. Together with programmable settings, they help simplify repeated configuration tasks during circuit development and system evaluation.

6. Designed for Electrical Engineering Workbenches

The KQ7901 is suitable for engineering workbenches where adjustable DC power, programmable settings, and controlled output conditions are required. It provides a flexible power source for circuit design, component evaluation, and electrical system development.
