About this item

  • Accurate and Reliable: AC current sensing switch provides induction range and general solid-state output with current range of 0.2-30A. Its measurement accuracy is better than 1%, which is suitable for the measurement of any waveform
  • Wide Measuring Range of Current Sensor: Miniaturization current switch can measure the current and voltage of any waveform, such as DC, AC, pulse, triangular waveform, etc., and can faithfully reflect even the transient peak current and voltage signals
  • High Response Speed: Flameproof adjustable AC current sensing switch will immediately close a group of contacts once current is detected. Response time: ≤ 200ms, the extremely high response speed also adds another layer of guarantee to the safety performance of flameproof adjustable AC current sensing switch
  • High Safety: Self powered sensing switch for automated industrial equipment uses the electromagnetic induction principle of current and adopts advanced output detection, monitoring, protection and alarm products developed by non power supply technology. At the same time, it has wide frequency band, strong anti-interference ability and strong overload ability. A series of guarantees escort the safety of self powered sensing switch for automated industrial equipment
  • Wide Scope of Application: Adjustable isolation AC current switch is applicable to substation, variable frequency speed regulation device, inverter device, electroplating, electric locomotive, street lamp monitoring, coal mine and other automation industries requiring current monitoring. NC / no current switch can control various automatic industrial equipment, flashlight, buzzer, relay, microcontroller or other electrical load devices

Built a a timer shut off circuit for my air compressor if it runs for more than 15 minutes, it'll shut it down just as a safety against a broken line. When I'm not near it, it won't burn itself out
