systems. The LLV series is designed to meter line to line voltages and the PNV series is designed to meter phase to neutral voltages. The transducers provide
three discrete 4 to 20mA outputs that are proportional to the three phase input voltages. The input voltages scale does not meter down to zero Volts, instead it
is limited to the normal useful range of input voltages for a particular system. For example: The model PNV-120 has an input signal range from 90 to 150 V ac
and will yield an output of 4 to 20 mA dc for that range. The output is true constant current driver and is unaffected by resistance variations from 0-600 ohms
in the output loop. An external 24Vdc supply is needed to provide power for the internal solid state circuitry. The power supply input has reverse polarity
protection to prevent damage from an accidental miswire. The high accuracy solid state circuity is average responding calibrated to read RMS. This device is
an ANSI/ISO 50.1 Class L3 transmitter.
