Technical Data

Description

Analog Panel Meter with Moving-Coil Movement and Integrated Power Converter

for Active or Reactive Power

Depending upon type of system and power, the power converter consists of one,

two or three multipliers. The multipliers function in accordance with the

TDM process (time division multiplier). The output signals from the multipliers are

added and fed to the moving coil mechanism.

Reference Conditions

Notes Concerning the Determination of Measuring Ranges

The upper measuring range value should be a standard value per DIN 43701:

1 − 1.2 − 1.5 − 2 − 2.5 − 3 − 4 − 5 − 6 − 7.5 − 8

and corresponding powers of ten.

The upper measuring range value must lie within a range of 0.6 to 1.2 times apparent

power.

Apparent power S is calculated from the primary values from the current and voltage

transformers:

where U equals phase-to-phase voltage
