Measuring transducer for active power in the middle frequency range, Frequency range DC/10 Hz – 20kHz Measurement of direct, alternating, pulsed and mixed currents
The measuring transducer MFP..-MU is used for the transformation and isolation of the active power in the middle frequency range into an impressed direct current and direct voltage signal. It is used in power supplies of welding systems, UPS systems, switch-mode power supplies, induction furnaces, systems with frequency converters, three-phase and servo drives, generators and others.
The parameters to be measured are transmitted to the analog multiplier via internal hall effect current transformers and voltage dividers. The instantaneous values of current and voltage are then multiplied and formed as the mean value of a direct voltage matching the active power in a downstream integration stage. Alternating current parameters of any waveform may be measured. The galvanic isolation between input and output signals is done using optocoupler. A downstream amplifier supplies the impressed direct current and direct voltage signals. Both outputs are no-load proof and short-circuit proof. Connecting the two outputs is not permissible. An auxiliary voltage is required.
