ET5406A+ Programmable Electronic Load Tester 200W 120V 20A, High-Precision DC Load with CC/CV/CR/CP Modes Battery Capacity Test USB Remote Control LCD Display for Power Supply Charger Testing

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 TestingThis 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 OperationThe 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 DesignThe 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.Package Included：1 × DC Electronic Load 1 × Power Cord 1 × Tset Clamp1 × Certificate1 × User Manual
