- zero level crossing method
- the output is a linear function of the phase shift between the inputs
- voltage-to-current, voltage-to-voltage
- frequency range: from 45 to 65Hz
- input-to-output-to-power supply isolation: 4000Vr.m.s.
- measuring range: 20 to 120% of rated input
- conversion accuracy: < 0,5%
- compact design
- designed for DIN 35 rail mounting |
The converter has been designed to convert the
magnitude of a phase shift between two voltages of the same frequency into a unified DC voltage or
current. Its operation is based on comparing the time difference between the zero point crossing time
instants with the duration of the period. The current input is isolated from the voltage input by
means of a measuring transformer. After the signal waveform is shaped and the phase difference is
calculated, the signal is fed via an isolating optocoupler into the output amplifier. It is converted
into an unified output signal. The output is proportional to the phase shift between the inputs. Both
the input and the output circuit are overload-protected.
Owing to the measuring principle used, the converter cannot be
applied to heavily distorted waveform voltage or currents. |
