18 kW High-Voltage Output
The standard 6U chassis fits seamlessly into 19-inch racks. A single unit delivers 1200 V/30 A/18 kW wide-range output, with 0.05% voltage/current setting accuracy and 10 mV/1 mA setting and readback resolution for stable, precise DC output.
Real-Time Waveforms and Extended Data Logging
Switch to real-time voltage and current waveforms with one touch for a clear view of output dynamics. USB screenshot capture and local data logging enable anomaly monitoring for up to 72 hours, simplifying result storage and troubleshooting.


Flexible CC/CV Priority Modes
Select constant-voltage or constant-current priority to suit different loads and suppress startup overshoot. Adjustable voltage and current slew rates support complex loads and demanding slew-rate tests.
100-Step Sequencing and Dynamic Monitoring
The LIST function supports up to 100 programmable output steps, configured from the front panel, PC software, or a CSV file imported via USB. Real-time voltage and current waveforms make output dynamics easy to monitor and anomalies quick to identify.


Professional PV P-V Curve Simulation
Optional P-V curve simulation reproduces solar panel I-V characteristics under different environmental conditions. Built-in EN 50530 and Sandia models support static MPPT efficiency testing and coordinated control of multiple power supplies.
Versatile Interfaces for Easy System Integration
Standard USB Device, RS485, and LAN interfaces support SCPI commands. The PC software enables remote monitoring, parameter configuration, and data logging. Also provided are a front-panel USB Host port, remote-sense terminals, DC output terminals, and AC input terminals.
