DIN Rail mounted AC voltage transducers suitable for converting AC voltage to a proportional mA or voltage output. Options for average sensing and true RMS, plus unit for monitoring deviations in narrow bands around a specified nominal voltage. The EVCC and EVCP are average sensing RMS calibrated while the EVCR is a true RMS sensing. The EVCX, EVXP and EVXR are designed to monitor the deviation of a voltage over a narrow band around the specified nominal voltage. The EVCC and EVCX transducers are self powered whilst all other AC voltage transducers are powered from a large choice of AC or DC auxiliary power options. The 4kV isolated mA or voltage output signals can then be monitored by suitable display, loggers and other monitoring equipment.
EVCC – Self-powered zero based output
EVCP – Auxiliary powered live zero output
EVCX – Self-powered expanded scale
EVXP – Auxiliary powered expanded scale
EVCR – Auxiliary powered true RMS
EVXR – Auxiliary powered true RMS Expanded scale
The EVCC and EVCP are average sensing rms calibrated while the EVCR is a true rms sensing, rms calibrated transducer typically used for measuring distorted waveforms. The EVCX, EVXP and EVXR are designed to monitor the deviation of a voltage over a narrow band around the specified nominal voltage. The EVCC and EVCX transducers are self powered whilst all other AC voltage transducers are powered from a large choice of AC or DC auxiliary power options. The 4kV isolated output signals can then be fed to analogue meters, digital meters, PLC’s or building management systems.
