80V 20A 400W Test Fixture Integration Programmable DC Power Supply with List Sequencing &Remote Sense KQ7901

KUAIQU KQ7901 80V 20A 400W  Test Fixture Integration Programmable DC Power Supply with List Sequencing & Remote Sense

Description

The KUAIQU KQ7901 Test Fixture Integration Power Supply is designed for test fixture developers, electrical test equipment manufacturers, and system integrators building customized electronic inspection platforms. Combining programmable DC output, a 4.3-inch TFT color display, five-digit voltage and current readouts, and real-time power monitoring, it provides a flexible power source for integrated test setups.

With local List sequence programming, USB data import, 100 configurable parameter memory groups, and USB, RS232, and RS485 communication interfaces, this programmable power instrument can be incorporated into compatible test fixtures and electrical measurement systems. Remote Sense compensation, reverse-polarity protection, OCP and OVP safeguards, and panel locking further support reliable operation in engineering test environments.

Key Features

1. Flexible Power Integration for Custom Test Fixtures

The KQ7901 provides programmable DC output for custom electronic test fixtures, interface-board verification platforms, and equipment development projects. Its digital controls and configurable output parameters allow integrators to establish suitable supply conditions for different devices under test, subject to the instrument's rated output range.

2. 4.3-Inch TFT Display for Instrument Panel Integration

The 4.3-inch TFT color display presents voltage, current, power, and curve information in an accessible interface. Adjustable brightness supports different workbench and equipment environments, while Chinese and English language switching simplifies operation for engineering teams and equipment users.

3. Five-Digit Readouts and Direct Parameter Entry

Five-digit voltage and current displays, real-time power monitoring, rotary encoder adjustment, and numeric keypad entry provide convenient parameter configuration during fixture development and equipment commissioning. These controls help technicians configure supply settings when validating new test hardware or maintaining established test platforms.

4. 100 Memory Groups for Multiple Test Configurations

The KQ7901 stores up to 100 parameter groups, including voltage, current, OCP settings, and OVP settings. Integrators can organize suitable configurations for different test fixtures, board variants, and inspection procedures, reducing repeated manual setup when switching between supported test conditions.

5. Local List Programming and USB-Based Sequence Import

List programming supports the creation of predefined output sequences directly on the instrument, while USB drive import allows compatible test data to be transferred into the power supply. This is useful when developing multi-step power application procedures for customized inspection fixtures and repeatable equipment demonstrations.

Confirm supported file formats, sequence length, timing resolution, and transition behavior before implementing complex automated test routines.

6. USB, RS232, and RS485 Interfaces for System Communication

Multiple digital interfaces provide options for connecting the KQ7901 to compatible computers, controllers, and test equipment. This flexibility supports instrument integration projects that require external parameter configuration or coordinated power control.

Actual integration depends on the supported communication protocol, command set, software compatibility, and the control architecture of the host system.

7. Remote Sense Compensation for Fixture Wiring

Remote Sense compensation helps account for voltage drops across output cables by sensing the voltage at the load connection. This can be valuable in test fixtures where wiring resistance affects the voltage reaching the device under test. Correct Sense connections and operation within the instrument's specifications are essential.

8. Voltage, Current, and Power Curve Visualization

The graphical interface can display two of the following parameters simultaneously: voltage, current, and power. This helps equipment developers observe output behavior during setup verification and troubleshooting, complementing measurements from external test instruments where required.

9. Reverse-Polarity Protection for Battery-Related Fixtures

Built-in battery reverse-polarity protection triggers an alert when an incorrect battery connection is detected. This helps identify wiring mistakes in applicable battery-interface and protection-circuit test fixtures. Verify the supported connection method and battery testing requirements before use.

10. OCP, OVP, Forced CV Mode, and Panel Lock

Overcurrent protection and overvoltage protection provide additional safeguards during test equipment commissioning. Forced constant-voltage mode is designed to maintain CV operation under specified conditions, while panel locking helps prevent accidental changes to configured settings during fixture operation.

11. Auxiliary USB-A and USB-C Charging Outputs

The USB-A and USB-C auxiliary outputs provide additional power options for compatible accessories and USB-powered devices used alongside the test setup. Real-time output monitoring helps users observe the auxiliary output status. Confirm supported charging protocols and output ratings before powering specific devices.
