Core Advantages

  • Dual-Channel Efficiency: Simultaneously test 2 devices (e.g., 2 chargers/ batteries) without extra tools, cutting testing time by half for production lines.
  • High Precision: 1mV/1mA resolution captures tiny signal changes, ensuring accurate data for R&D and quality inspection.
  • Multi-Scenario Adaptability: Covers battery capacity testing, LED power simulation, power supply dynamic performance testing, and short-circuit simulation—one device meets diverse needs.
  • Smart & Safe: Power-off data retention saves parameters; dual over-temperature protection and adjustable alarms reduce equipment damage risks.

Applicable Scenarios

  1. Production Line Testing: Simultaneously test 2 chargers/switch power supplies, quickly verifying qualification with PASS/FAIL function.
  1. Battery Industry: Parallel testing of 2 batteries to compare capacity, discharge performance, and internal resistance.
  1. LED & Electronic R&D: Simulate dual LED power loads for stability testing; use dynamic/scan modes for prototype verification of multi-output power supplies.
  1. Lab & Education: Suitable for scientific research (parallel signal analysis) and electronics courses—helps students master dual-channel load operation.

Why Choose ET5420A+?

  • Efficiency Boost: Dual channels replace 2 single-channel loads, saving space and cost for enterprises.
