Half-Cycle Precision Like Never Before

4 channelP.M.S.enables remote On/Off control of each socket via computer, while simultaneously detecting and analyzing complex AC currents and voltages — even over short half-cycle intervals. It performs real-time measurement and display of True-RMS, Mean, and Peak-to-Peak voltage, along with True-RMS current, all integrated with a built-in dual-stage surge protection system to safeguard your sensitive equipment.

Each socket operates independently, with each channel incorporating configurable surge protection for enhanced safety.

  • AC waveform detection (oscilloscope-like capability without display)
  • AC voltage & current measurement system, comparable to professional multimeters
  • The device’s features and customizable settings allow users to define current and voltage thresholds, enabling independent management of voltage and current errors without relying on a computer

To operate the Power Switch and fully utilize its capabilities, we provide three dedicated software tools:

  1. Channel Control & Monitoring
  2. Voltage and Current Control
  3. Voltage and Current Monitoring

For a complete overview and step-by-step demonstration, please watch the video below.

  • Equipped with RS485 and USB interfaces
  • The unit is equipped with US AC power entry sockets
  • Network-capable, offering expansion of up to 16 power switch units
  • Enables remote on/off control of each channel via computer, utilizing relay switches
  • The computer interface is isolated from the power line with protection up to 6.5 kilovolts
  • LED indicators on the body display current and voltage errors and facilitate outlet selection
  • Compatible with LabView, enabling voltage, current, and error monitoring. 
  • Each of the four channels can control power ON/OFF, supporting a maximum current of 5 amps per outlet continuously, for a total of 20 amps at 110V RMS and 16 amps at 220V RMS across all channels
