Tonghui TH8405 DC Electronic Load

The TH8400 Series offers a cost-effective yet high-performance lineup of programmable DC electronic loads, featuring power ratings from 175 W to 2000 W, voltage capabilities of 150 V or 500 V, and current up to 240 A. With a dynamic bandwidth reaching 25 kHz and a high 500 kHz sampling rate, this series helps engineers test DC power supplies, batteries, solar arrays, EV components, and electronic components with precision and confidence.

Key Features

• Wide Operating Range: Tailor the load to your specific needs with power ratings from 175W to 2000W, input voltage options of 150V and 500V, and current capabilities ranging from 15A to 240A.
• High-Speed Dynamic Testing: Featuring a dynamic test frequency of up to 25kHz and a rapid measurement sampling speed of up to 500kHz, the TH8400 is perfectly equipped to capture transient characteristics and test the dynamic response of modern power supplies.
• Exceptional Measurement Accuracy: Achieve reliable and repeatable results with high-resolution measurements of 1mV and 0.1mA. The low ripple and noise floor ensure that the measurements you take are true to your device’s performance.
• Advanced Waveform Analysis: Go beyond standard measurements with integrated features for ripple and peak value analysis. The TH8400 can measure and display voltage/current ripple (Vp-p/Ip-p) and peak values, providing critical insight into the stability and quality of your power source.
• Unique On-Screen Waveform Display: A standout feature of the series is its ability to display voltage and current waveforms directly on the VFD screen. This allows for real-time analysis and troubleshooting without the need for an external oscilloscope, saving time and bench space.
• Comprehensive Operating Modes: With 11 distinct operating and measurement functions, the TH8400 series offers ultimate flexibility. Standard modes include Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR), and Constant Power (CP).
