The ET5406A+ Programmable DC Electronic Load is designed for engineers, laboratories, R&D teams, and production lines that require stable and accurate electronic load testing. With a 200W rated load, 0–120V voltage range, and 0–20A current range, this tester meets the needs of power supply development, mass-production inspection, and battery capacity evaluation.

Professional Multi-Mode Testing
This tester provides not only the standard CC, CV, CR, and CP modes but also five special test functions:
Battery Test Mode: Measures discharge capacity up to 9999Ah.
Dynamic (Tran) Test Mode: Evaluates the transient response of power supplies.
Scan Test Mode: Tests output continuity over a defined range.
List Mode: Simulates multi-step loading for R&D and production testing.
hort-Circuit Test: Safely simulates short-load scenarios.
High Accuracy & Stability
With high-resolution 1mV/10mV and 1mA/10mA measurement steps, the ET5406A+ ensures precise and repeatable results—ideal for quality control and laboratory analysis. The built-in memory stores test data in case of unexpected power loss.
Safe & Intelligent Operation
The system includes OCP, OVP, OPP, OTP protections, plus reverse polarity alert, ensuring secure operation. The intelligent cooling fan automatically adjusts speed to control internal temperature while minimizing noise.
Durable & User-Friendly Design
The aluminum housing, anti-slip rubber feet, and reinforced structure make it suitable for industrial environments. The bright LCD segment display and silicone buttons offer comfortable and reliable operation.
