Split Core DC Volt Transducer – 4DS by Sentran Corp

Product Description

The 4DS by Sentran Corp is a split core DC volt transducer.  It takes up to 500A and outputs a corresponding 0-5 Vdc signal.

The 4DS rectifies the AC sinewave to obtain a DC output.  Only passive rectifiers are used allowing the unit to be self-powered.  Note this is not a true RMS conversion.  This split core DC volt transducer is 1% accurate over the range 10% – 100% and has a 0.5% ripple.

The hinges cannot be easily broken (made of steel).  Many customers prefer this model over the DCT-0036-500 and DCT-0024-250 due to its similar cost and high level of quality.  The 4DS is made in the USA.

The Amperage / Size option indicates the 4DS series that we stock.  Other available sizes can be ordered – see data sheet for full details on available options.  Available output voltages include: 2.5 Vdc, 5.0 Vdc and 10 Vdc.
