請來信詢價

Emerson EC3-X33 是一款具有穩定過熱控制的獨立式通用過熱控制器,採用步進電子驅動的電子膨脹閥,適用於空調,制冷和工業應用,如制冷機、冷藏室和熱泵等。

安裝控制器需要使用ECD-002顯示器配件。

  • 過熱控制,連同Emerson的步進電機驅動電子膨脹閥 EX4-EX8進行
  • 蒸發壓力限制 (MOP)
  • 低及高過熱報警
  • 監測傳感器和傳感器接線以及傳感器和線路故障的檢測
  • 自動保護報警及保護壓縮機,例如,故障安全操作。
  • 鋁製支架可安裝於DIN rail
  • 附Terminal Kit一組
  • 本產品需搭配ECD-002控制面板使用

描述

The EC3 is a stand-alone universal superheat controller for stable superheat control with stepper motor driven electronic control valves and is used for air conditioning, refrigeration and industrial applications such as chillers, industrial process cooling rooftops, heat pumps, package units, close controls, cold room, food process and air driers. The EC3-X33 requires the use of the ECD-002 display key pad unit for setting up the controller.
Features
  • Superheat control in conjuction with Emerson stepper motor driven electrical control valves EX4-EX8
  • Limitation of evaporating pressure (MOP)
  • Low and high superheat alarm
  • Monitoring of sensors and sensor wiring and detection of sensor and wiring failures
  • Intelligent alarm management to protect the compressor, i.e fail safe operation
  • Integral rechargeable battery to close EX control valves in case of power loss.
  • Electrical connection via plug-in type screw terminal
  • Aluminum housing for DIN rail mounting
