Integrated Source and Load with One-Touch Switching
The OWH67B integrates a bidirectional DC power supply and regenerative DC electronic load in one unit. Source mode supports CC, CV, and CP, while load mode supports CC, CV, CR, and CP. Switch between modes seamlessly with the Mode Select key.
89%+ Energy Regeneration for Lower Test Costs
With regenerative efficiency exceeding 89%, absorbed load energy is fed back to the grid, reducing heat output and cooling requirements to lower energy costs in high-power testing.
High-Fidelity Battery Simulation
Seven built-in battery models combine equivalent-circuit, SOC-OCV curve, and dynamic RC network algorithms to reproduce the charge and discharge characteristics of different battery types, simplifying battery and energy-storage product testing.
PV Simulation and MPPT Testing
The -S models support EN 50530, Sandia, and user-defined SAS curves for simulating PV module output characteristics. Optional software enables multi-unit MPPT tracking tests.
Wide-Range, High-Accuracy Bidirectional Output
Delivers wide-range output up to 60 V, ±120 A, and ±1800 W with 0.05% control accuracy for stable, precise power. CV, CC, and CP modes support a wide range of precision power and test applications.
LIST Sequencing and Dynamic Monitoring
Supports up to 100 programmable output steps, configured from the front panel, PC software, or a CSV file imported via USB. Displays voltage and current readback curves for the latest 60 seconds and supports screenshot capture, data logging, and file management.
Safe Connectivity and Automated Control
Built-in OVP, OCP, OPP, and other protections ensure safe operation. Standard USB Device, USB Host, LAN, and RS485 interfaces support SCPI commands and enable remote configuration and centralized control via PC software.
