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


SKU: 3503_0 Categories: , Tag:


The 3503_0 Phidgets i-Snail-VC-100 Current Sensor 100 Amp 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 output voltage into AC Amps (RMS) is:

AC Amps (RMS) = V * 20


This sensor connects to a Phidget InterfaceKit or Hub with a voltage input. See the Compatible Products tab for details.
