IRFrms rms converter module

IRFrms RMS Converting AC Transducer

RMS Converter Transducers for AC to DC or AC+DC to DC Proportional Output

The IRFrms is an instantaneous to true RMS converter, offering high precision in converting AC or AC+DC signals into an isolated DC signal that represents the true RMS value. It matches the performance of high-end true RMS voltmeters, providing scalable outputs for voltage or 4-20mA current loops, with options for isolated or non-isolated configurations.

Applications:

Typically used with voltage output current probes, current shunts, and current transformers.
Ideal for delivering isolated signals for connection to computers, data loggers, or SCADA systems.
Can be configured to work with most current probes, sensors, and data loggers.
Suitable for high voltage applications (up to 1000V) using model VTHR.
Provides both RMS and instantaneous outputs for enhanced diagnostic and metering capabilities.

Key Features:

True RMS Conversion: Converts AC or AC+DC signals to DC output.
RMS and Instantaneous Outputs: Allows current probes and CTs to have both outputs for diagnostics and metering.
High Voltage Isolation: Input/output isolation up to 1000V peak with the Iso option.
