About this item

• Seamless Connectivity for Automated Control: Integrate the load into your automated test system via USB, RS232, or RS485 interfaces with full SCPI protocol support. With a wide operating range (0-300V, 0-30A, 300W power, 1.1V@30A min. operation), it provides the flexibility and control needed for both R&D and production line environments
• High-Speed Dynamic Testing with Adjustable Slew Rate: Test device dynamic characteristics by simulating real-world current fluctuations. The load switches rapidly between two preset values (Level A/B) at up to 5kHz. The transition time is precisely configured via an adjustable current rise rate from 0.001A/μs to 2A/μs, enabling accurate characterization of power supplies and components under transient conditions.
• Comprehensive Protection for Device Safety: Safeguard your equipment with multi-layered protection features, including Over-Current (OCP), Over-Voltage (OVP), Over-Power (OPP), Over-Temperature (OTP), and Reverse Polarity Protection (RPP). These built-in safety mechanisms ensure reliable operation and prevent damage to both the load and the device under test
• Integrated Battery Charge/Discharge Testing: Evaluate battery performance with a complete charge/discharge test system. A power supply charges the DUT, while the electronic load controls discharge—all managed by PC software. Set parameters, cutoff conditions, and cycle counts to automatically output charge/discharge curves and capacity curves for in-depth performance analysis
• User-Friendly Design with High-Resolution Display: Featuring a compact and portable form factor, this programmable electronic load is built for the bench or the field. The 2.8-inch TFT color LCD provides clear readbacks with high resolution (1mV/0.1mA), allowing for precise monitoring and adjustments during operation
