890 Fuel Cell Test Loads


모델 890은 중소 규모의 단일 셀  숏스택 테스트를 위한 소형 랙 마운트 벤치탑 장치로, 다범위 프로그래밍 가능한 전자 로드, 연료 흐름 및 온도 제어, 데이터 수집 기능이 있는 연료전지평가로드입니다. 881 내장 FRA를 옵션으로 선택하면 HFR 및 EIS(Electrochemical Impedance Spectroscopy) 측정이 가능합니다.885 Fuel Cell Potentiostat 과 호환돼 LSV/CV 실험 등이 가능합니다.


890의 다중 전류 범위 기능은 광범위한 테스트 애플리케이션 및 테스트 환경에서 다용성과 성능을 향상시킵니다.

 Features


  • Electronic load with three current ranges for accurate measurement over a wide dynamic range
  • Control signals for two (2) main mass flow controllers plus five (5) additional mass flow controllers
  • Continuous real-time cell resistance and IR-free voltage measurement by current interrupt
  • Whole cell voltage plus two high-impedance reference electrode inputs for half-cell data
  • Optional internal impedance analyzer for EIS and continuous real-time high frequency resistance (HFR)
  • Simultaneous 3 channel impedance measurement using whole cell and half-cell
  • Cell main terminals and sense inputs tolerant of non-isolated cell
  • Three (3) internal controllers for anode and cathode humidifier and cell temperatures
  • Constant current, voltage or power control mode
  • Contact inputs for three pressure sensors or alarms
  • Low voltage output signal to control purge gas valves and to indicate alarm condition
  • RS485 digital interface for external temperature controllers
  • Safety features include detection of alarm conditions and automatic hardware shutdown for safe, reliable operation

Knowledge of systems integration and electrical wiring conventions is required.
We may decline to provide 890 systems if there is concern about integration expertise or capability.
