The IRF-rms is a useful true rms converter module, easily matching the performance of high-end true rms voltmeters.   Its purpose is to convert ac signals to a dc signal representing the rms.  Its output signal can be voltage or current.

The IRF-rms is used typically with voltage output current probes and current transformers.  It can be configured to operate with most current probes, current sensors and dataloggers.

The CTH summation transducer is intended to sum three 0-10V dc analog signals into one 0-10V output.  A typical application is where a sum (eg equal to total power) is required from 3 separate watt transducers

IRF-RMS AC rms input to dc output converter

-- Bandwidth: DC-50kHz
-- Ac or dc coupled versions
-- Computes AC rms or AC+DC rms
-- 0.5% accuracy
-- -20°C to +60°C operating range
-- Input impedance 50ohm or 100kohm
-- Output impedance 100ohm (50 ohm optional)
-- Accurate with waveform crest factors: 1 - 5
-- Input ranges: 2mV to 50V input (user specifies input range)
-- Wide range of dc outputs: 0-100mV, 0-1V, 0-5V,
   0-10V, 0-20mA, 4-20mA and 5-25mA
-- Power: 12, 24, 48, 110Vdc, 110Vac or 230Vac power

Part number example:
Input = 2Vrms,  Output = 0-10Vdc, dc coupled with 24Vdc power
Part no. = IRFrms / 2 / ac+dc / 10 / 24Vdc
