Programmable DC Power Supply 80V 900A 30kW

High-Current DC Power for Industrial Testing

The KINGPO Programmable DC Power Supply is used when the DUT requires controlled DC voltage and current instead of a fixed-output power adapter or a low-power bench supply. With 30kW output power and up to 900A current, this configuration is suitable for high-current test applications where stable DC power, protection control and repeatable output conditions are required.

For R&D laboratories, the power supply can support device verification, electronic module testing and controlled DC power experiments. For production-line users, it can provide repeatable DC output for functional testing, burn-in or aging test stations. For industrial automatic test systems, the communication interfaces and command compatibility help integrate the unit into PC-controlled or user-developed test platforms.

This page is based on the HSW68-80-900-30000 configuration. The HSW series can be configured across different voltage, current and power levels, so the final output range, cabinet layout, parallel configuration, software control requirements and acceptance documents should be confirmed before ordering.

Output Control and Automatic Test Integration

The HSW68 programmable DC power supply supports both local operation and remote programming. Operators can set voltage and current from the front panel during daily use, while system integrators can connect the unit to automatic test software through multiple communication interfaces.

Key control and integration capabilities include:

• Front-panel voltage and current setting
• Constant voltage / constant current auto crossover
• Remote sensing for load cable voltage drop compensation
• RS232, RS485, USB, CAN and LAN communication interfaces
• External trigger TRIG IN / OUT
• SCPI and MODBUS-RTU compatible command set
• LIST, RAMP and timer functions for sequence output
• Output monitoring and protection status indication

These functions make the unit suitable for automated laboratory test benches, production-line test stations and industrial DC power test systems where repeatable control is required.

Technical Specifications

The following specifications are based on the HSW68-80-900-30000, 80V / 900A / 30kW configuration. Final specifications should be verified against the confirmed order model, cabinet integration method, parallel configuration, input power requirement and acceptance documents before production.

Operating and Mechanical Information

Power Module and Multi-Unit Cabinet Configuration

The catalog information includes a single power module reference and a multi-unit cabinet system reference. This is important for quotation and installation planning.

The listed 440mm W × 600mm D × 132mm H dimension and approx. 26kg weight refer to a single power module reference. If the project requires a multi-unit cabinet system, the final cabinet size, weight, busbar layout, distribution box, cooling structure and safety documentation need to be confirmed according to the final integration method.

For high-current or high-power projects, KINGPO may need to confirm:

• Required voltage, current and total power
• Single-unit or parallel multi-unit configuration
• AC input power and site power condition
• Cabinet quantity and cabinet layout
• Copper busbar and distribution box requirements
• Cooling and ventilation conditions
• Communication interface and software control requirements
• Safety documents, inspection requirements and acceptance criteria

This configuration review helps avoid undersizing the power source or misunderstanding the mechanical installation requirements.

Typical Applications

 · Laboratory DC Power Testing

The programmable DC power supply can be used as an adjustable DC source for R&D verification, device behavior checks, component testing and controlled laboratory experiments. Engineers can set voltage and current according to the DUT requirement and monitor output conditions during testing.

 · Production-Line Testing and Aging Tests

For manufacturing QA, the unit can provide repeatable DC output for functional tests, burn-in tests and aging test stations. Remote communication and sequence functions are useful when the power supply needs to work as part of a PC-controlled production-line test process.

 · Battery-Related Test Setups

The unit can be used as a programmable DC source for battery-related test setups where adjustable voltage or current is required. However, battery cycling, charge/discharge automation or regenerative functions should not be assumed unless the complete system configuration is confirmed.

 · Motor and Controller Testing

The 80V / 900A / 30kW configuration can support high-current DC supply needs for motor-related products, motor controllers and industrial DC load applications. Load current profile, startup behavior, duty cycle and protection requirements should be reviewed before model confirmation.

 · Electronics and Industrial Load Testing

The system can support electronics, power modules, DC input equipment and industrial load testing where controllable voltage/current output is required. For special loads, the test duration, current waveform and cooling condition should be confirmed before quotation.

 · Automatic Test System Integration

With RS232, RS485, USB, CAN, LAN, external trigger I/O, SCPI and MODBUS-RTU support, the power supply can be integrated into automatic test systems or user-developed control software. Interface protocol and software requirements should be confirmed before final configuration.

Technical Features

30kW High-Power DC Output

This configuration provides 0–80V, 0–900A and 30kW DC output for high-current industrial test applications. It is suitable when a standard bench DC supply cannot provide enough current or power for the DUT.

CV / CC Auto Crossover

The power supply supports constant voltage and constant current auto crossover. This helps protect the DUT and allows the system to respond when the load condition changes during testing.

10mV / 10mA Setting and Readback Resolution

For this configuration, voltage and current setting/readback resolution is 10mV / 10mA. This supports controlled output adjustment and measurement feedback during laboratory or production testing.

Remote Sensing Compensation

Remote sensing helps compensate voltage drop on load cables. This is especially important in high-current applications, where cable resistance can affect the actual voltage delivered to the DUT terminals.

Multiple Communication Interfaces

RS232, RS485, USB, CAN and LAN interfaces are available for remote control and automatic test integration. This allows the power supply to connect with PC software, production-line systems or user-developed control platforms.

SCPI and MODBUS-RTU Compatible Commands

The SCPI and MODBUS-RTU compatible command set supports integration with existing test software or customer-developed programs. Interface details should be confirmed according to the customer’s control environment.

LIST, RAMP and Timer Functions

LIST, RAMP and timer functions support sequence output and simple automated test tasks. These functions are useful when the test requires voltage or current changes over time.

Protection Functions

The catalog lists over-voltage, over-current, over-temperature and short-circuit protection. Protection thresholds and behavior should be confirmed according to the selected configuration, DUT characteristics and test procedure.
