  • kWh range 999999.99 kWh
  • Run hour range 9999.59 hours
  • Password protected
  • Quick & easy to install
  • Sealed Dust proof enclosure suitable for Panel mounting
Additional Features DEM9024F
  • Two isolated DC Voltage Channel
  • Four DC Current Channels
  • DEM9024F used to monitor two independent BTS Systems with different DC Voltages in a single mete
  • Grouping of voltage and current for measurement Isolation between voltage channels
Optional Features
