ET5304 Programmable DC Electronic Load: High-Power for Heavy-Duty Power Testing

Frustrated by loads that can’t keep up with high-power, high-current testing demands? The ET5304 delivers 1200W power, 0-300V wide voltage range, 0-40A current + 1mV/1mA high resolution—perfect for testing high-voltage industrial power supplies, large batteries, heavy-duty chargers, and industrial electronics in R&D labs, production lines, and industrial sites.

User-Friendly & Durable Design

  • Clear Visualization: 3.5-inch TFT LCD with bilingual (Chinese/English) display, presenting voltage, current, power, and test mode data clearly at a glance.
  • Easy Operation: Intuitive interface supports one-key entry/exit of test modes; built-in key lock prevents accidental misoperation during critical tests.
  • Sturdy & Quiet: Reinforced housing withstands heavy-duty industrial use; smart fan speed control reduces noise during low-load operation; built-in buzzer provides real-time fault alarms.

Core Advantages

  • Wide Voltage & High Power: 0-300V voltage range and 1200W power capacity handle high-voltage heavy-duty devices, filling the gap of low-voltage loads.
  • High-Precision Testing: 1mV/1mA resolution captures tiny signal changes, ensuring accurate and reliable data for industrial R&D and production quality control.
  • Multi-Mode Adaptability: Covers basic constant tests to advanced professional tests, replacing multiple single-function tools and streamlining testing setups.
  • Safe & Convenient: Multi-layer protection (over-voltage, over-current, over-power, over-temperature) safeguards the load and tested devices; power-off data retention saves parameters, and remote control fits automated industrial testing.

Applicable Scenarios

  1. Industrial Production Lines: Quickly verify the performance of high-voltage industrial power supplies and heavy-duty chargers via the PASS/FAIL function, improving testing efficiency.
  1. Battery Industry: Test the capacity, discharge performance, and internal resistance of large high-voltage batteries (e.g., industrial backup batteries, new energy vehicle batteries).
  1. Industrial R&D: Use dynamic and scan modes to analyze the stability of high-voltage power supply prototypes and heavy-duty electronic product performance.
  1. Labs & Education: Suitable for industrial electronics research and teaching, helping students master high-voltage heavy-duty load testing principles.
