3503_0 - i-Snail-VC-100 AC Current Sensor 100Amp


Product Features

The i-Snail VC-100 measures up to 100 amps AC on a wire that passes through its window. Connects to an analog input.

Product Description


The i-Snail-VC is a self powered AC current transducer that provides a 0-5V dc analog signal proportional to the AC current flowing through the device wire window (sine wave RMS calibrated).

The i-Snail-VC is ideal for load monitoring without the need for an external power supply. Factory calibrated, fixed ranges ensure superior accuracy and eliminate configuration and adjustments in the field, saving time and avoiding confusion. Color coded labels allow for easy identification of full scale range.

The 13.7mm (0.54") wire window accommodates a conductor up to AWG #2. Multiple turns of the primary wire may be used to alter the input range. Output voltage is clamped at 6.5V, and the unit delivers a linear output up to 120% overload (6V).

Note: The i-Snail current transducer measures the current in a single AC wire (either the positive or the negative). If you put the whole cable through the window the + and - wires will cancel each other out and the sensor will read a null current value.



The formula for converting SensorValue into AC Amps (RMS) is:

AC Amps (RMS) = SensorValue/10

Mounting Hardware






You can use the 3002 - Sensor Cable 60cm or the 3004 -Sensor Cable 350cm to connect the i-snail sensor to your Phidget. Just snip off the connector from one end of the sensor cable and connect the white wire to the + terminal and the black wire to the - terminal. The red wire is not used.

Mounting Hardware

Then, connect it to any device with an Analog Input.
