Power meter readings

  • Active energy consumption (kWh) and supply (kWh)
  • Reactive energy consumption (kWh) and supply (kWh)
  • Active power (kw) 
  • Reactive power (kvar) 
  • Apparent power (kVA)
  • Current (A)
  • Frequency (Hz)
  • Number of voltage failures
  • Current transformer ratio


Reading and setting parameters is user-friendly by a 38x28 mm graphic LCD display with LED backlight. This provides excellent visibility of numbers and letters.
Display language e.g. english or german can be selected by the keys.

Power meter configuration

Touch-sensitive control buttons are used for configuration. A sealable service button must be pressed for each configuration change.
The current transformer ratio (1 or 5 A transformer, up for up to 20000/5 or 4000/1 A) can be configurable several times.
