The IRF-rms is an instantaneous to true rms
converter module, easily matching the performance of high-end true rms
voltmeters. Its purpose is to convert ac, ac+dc signals to an
isolated dc signal representing the rms. Its output signal can be
scaled to meet most requirements, voltage or 4-20mA current loops, isolated
or non isolated.
The IRF-rms is used typically in
applications with voltage output current probes, current shunts and current
transformers - providing an isolated signal that can be connected to a
computer or data logger. The IRF-rms can be configured to operate with
most current probes, current sensors and dataloggers. High voltage
options up to 1000V are possible using model VTHR.
One key feature of the IRF-rms is that it allows current probes and CTs to
have both rms and instantaneous outputs, allowing the user diagnostic
possibilities as well as metering.
The IRF-rms can be powered from
5Vdc-125Vdc and ac 90-240Vrms

IRF RMS converter module
Part number examples:
Input = 2Vrms, Output =
0-10Vdc, ac+dc coupled with 24Vdc power
Part no. = IRFrms / 2 / ac+dc / 10
/ 24Vdc
Isolated version
Input = 110Vrms,
Isolated Output = 0-5Vdc, ac coupled with 24Vdc power
Part no. = IRFrms-iso / 110 / ac / 5 / 24Vdc |
CE marked and manufactured
