AC VOLTAGE FREQUENCY CONVERTER FOR GRID DISTRIBUTION SYSTEMS

Model:
	ACF

- industrial frequency measurement - auxiliary power supply: 230V 50Hz or 24V DC - nominal frequencies: 50 or 60 Hz - input-to-output-to-power supply isolation: 4000Vr.m.s. - input signal range: within 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 frequency of an input voltage into a unified DC voltage or current. After the input voltage is shaped and its period compared with that of a precision single-shot trigger circuit, the output voltage is smoother out. It is fed via an isolating optocoupler into the output amplifier. Both the input and the output circuit are overload-protected. This converter can be used for handling inputs whose waveforms are distorted. An analog filter is inserted into the converter input securing the converter response being limited to the fundamental frequency only.
