AC to DC Transducer – RMS-333 by Magnelab

Product Description

This AC to DC Transducer by Magnelab converts a low AC voltage signal into a low DC voltage signal.

The RMS-333 AC to DC transducer is designed to work with standard 0.333mVrms current transformers, potential transformers, sensors, and many different types of panel meters. The RMS-333 outputs 0.2, 0.5, 1, 2, 3 or 5Vdc and requires a 0-333 mVrms input. The unit is powered by a 3.1 – 35 Vdc operating voltage.

This unit is perfect for switching from an instrumentation AC voltage signal to any commonly used low voltage DC signal.  The output signal is proportional to the input.
