BSL Series High Power DC Source & Load
The BSL series 100kW/150kW/200kW/250kW/300kW for single system, up to 4 individual systems can be paralleled to up to 1.2MW system. BSL series has an auto-ranging output function. BSL standard models provide 1000V/ 1500V/2000V voltage and x2/x3/x4 current. BSL series uses bi-directional design, which can be used as DC power source or regenerative DC load. CV/CC/CP/CR operation modes are available for both sourcing and sinking. The BSL series incorporates a hardware architecture based on dual DSP and FPGA, delivering powerful processing and precise control. This platform enables real-time data sampling, and storage. The waveforms are displayed at a sampling rate of 10 k/s. BSL series provides comprehensive monitoring and protection for all critical components and communication links. This integrated design ensures system stability and reliability, making the BSL series a high-performance power solution for demanding industrial applications. With touch panel on the front panel, users can control the power source through GUI software. System status indicators and emergency stop button are installed on the front panel. RS485 and LAN interfaces are available for automated test applications.

Product Functions & Benefits

Bi-Directional (Re-generative)

BSL series can operate in source and sink mode. It has the capability to return the energy fully back to the grid.


Re-generative DC Load

BSL series can be used as regenerative DC electronic load. DC load simulation includes constant current, constant resistance, constant voltage, and constant power modes.



Automatic wide range output

BSL series has an automatic wide-range output function, such as: high-voltage small current or low-voltage large current (also applicable in sink power mode). The same model of power supply can cover a wider range of power applications.


Battery Test

BSL series provides battery test software and can be used for characterization of power battery packs. It is used to test the charging and discharging performance, temperature rise characteristics, and cycle life of the power battery pack. Through the GUI software, different charging and discharging profiles can be programmed, and test results are displayed in real time.


Battery Simulation

BSL Series provides battery simulation software and can simulate the charging and discharging characteristics of the power battery pack/package and provide a convenient and efficient testing method for the development and testing of new energy vehicle motors etc.


PV Simulation

BSL series provides PV simulation software and can be used to simulate IV curves of various solar panels, under various temperature and irradiance condition, and conduct static and dynamic MPPT tests according to EN 50530:2010. MPP Update Rate: 200Hz. Irradiance levels: 0 ~ 1500 W/m2. Temperature: -10 ~ +100°C. Temperature coefficient: +1% ~ -1%/°C.



Graphical User Interface

GUI software is installed in front touch panel, which uses Windows OS. The software provides following functions:

  • Output settings and limits

  • Sequence output settings

  • Display measurements: voltage, current, power, etc.

  • Capture, display and save output voltage and current waveforms Display power source faults
