True RMS voltage transducers in the loop
The ATVR series of voltage transducers offers true RMS measurement of AC voltage at 120, 250 and 400V.
The ATVR series of voltage transducers offers true RMS measurement of AC voltage at 120, 250 and 400V The new series provides +/-1% measurement accuracy and galvanic isolation between the primary and secondary circuits of up to 2.5kV
The bandwidth is 40Hz to 5kHz and the response time is below 250ms.
Linearity error is better than 0.5%.
The 4-20mA loop powered output is suitable for many types of control board (PLCs, computers etc).
The case is DIN-rail mounting at 22.5 mm with finger-safe terminals.
The ATVR series is particularly suitable for applications where the voltage measurement must be more accurate than a monitoring relay (eg voltage drop or overvoltage, which can have a critical influence on a PLC or computer).
The true RMS function also provides an accurate measurement of pulsed or noisy signals, such as those close to a variable frequency drive.
