  • Average RMS measurement for sinusoidal alternating voltage waveforms
  • 0.5% FS accuracy
  • Response time of 250 ms (10-90% step change)
  • DIN rail or panel mounting options
  • UL Recognized and CE certified for quality assurance


This CR Magnetics CR4811 series voltage transducer combines a potential transformer and signal conditioner, and is suitable for use in industrial automation systems. The transducer provides average root-mean-square (RMS) measurement for sinusoidal alternating voltage waveforms, with an accuracy of 0.5% full scale (FS) and a response time of 250 ms (10-90% step change). Mounting options include DIN rail or panel. This voltage transducer is Underwriters Laboratories (UR) Recognized and Conformité Européenne (CE) certified for quality assurance. It is suitable for monitoring linear, constant-speed loads that produce sinusoidal waveforms.

For the price I paid it is the best transducer. So far it has been working flawlessly. Build quality seems decent. The only downside of the transducer are the small terminals. I could hardly fit a 1mm2 wire with a ferrule in the terminals.---I just noticed that the price the transducer is listed for now if > $80 higher than I paid for... The transducers are still reasonably priced I think...

There are a few other options including LEM brand voltage transducers. The issue with the competition is the requirement of a bipolar power supply. Not so with the CR4810. I even tried it with a 12V power supply and it worked wonderful with almost perfect linearity. Do yourself a favor and pay the extra 20-25 dollars for this unit and save yourself time and money.
