Core Advantages

  • High-Voltage Adaptability: 0-500V voltage range covers high-voltage power devices (e.g., industrial power supplies, high-voltage batteries) that low-voltage loads can’t handle.
  • Precise Testing: 1mV/1mA resolution captures tiny signal changes, avoiding test errors; high accuracy ensures reliable data for R&D and production verification.
  • Multi-Scenario Use: From battery capacity testing and LED power simulation to power supply dynamic performance and short-circuit testing—one device replaces multiple tools.
  • Smart Features: Power-off data retention saves test parameters; list mode simulates multiple load status changes, meeting automated production line testing needs.

Applicable Scenarios

  1. High-Voltage Power Testing: Test switch power supplies, linear power supplies, and chargers with high output voltage—verify stability and qualification via PASS/FAIL function.
  1. Battery Industry: Measure capacity, discharge performance, and internal resistance of high-voltage batteries (e.g., industrial lithium batteries).
  1. LED & Electronic R&D: Simulate LED power loads to test stability; use dynamic/scan tests for prototype verification of high-voltage power supplies.
  1. Lab & Education: Suitable for scientific research experiments and electronics courses—intuitive operation helps students master high-voltage load testing principles.

Why Choose ET5411A+?

  • High-Voltage Expert: 0-500V range fills the gap of low-voltage loads, perfect for high-voltage power device testing.
  • All-in-One Efficiency: 14 professional functions (6 basic + 8 advanced) save cost and space vs. separate single-function tools.
  • Reliable & Safe: Comprehensive protection mechanisms prevent device damage from over-voltage, over-current, etc., extending service life.
