AC Voltage Transducers
Logic Beach distributes a quality line-up of AC Voltage transducers with full scale input ranges from 50 to 500Vac. Isolated outputs are available as loop powered 4-20mA or 0-5Vdc. Lower cost Average RMS parts can meet many standard grid or generator monitoring needs. For more demanding non-sinusoidal AC measurements (eg chopped wave or phase fired control systems), true RMS devices are available.
The average sensing model is optionally available with dual inputs and outputs in a single package… perfect for utility supply vs generator output monitoring.
True RMS devices are available for single phase and 3-phase (3 wire and 4-wire) applications.
Transducers are packaged in DIN rail mountable housings with optional mounting holes for direct surface mounting. Terminal strip connections are provided for Vac sense connections and output wiring.
