TA12-100 Current Transformer Sensor Products

Description

The TA12-100 is a Single Phase AC Current Transformer (CT) that has a ±5A range with 1000:1 turns ratio, high galvanic isolation, and a small size of 17.2mm x 9.5mm x 20.4mm (LxWxH). The output of this CT is a current signal, which needs to be converted to a voltage signal using a burden resistor.

The TA12-100 module has a 200Ω precision burden resistor across the transformer so that a voltage that can be read from the two output pins. An input of 5A into the transformer will produce 5mA through the resistor, giving a voltage output of (5mA)x(200Ω) = 1V. If an AC signal in the range ±5A is input into the transformer, then the output will be a positive and negative AC voltage in the range ±1V. If the output of this sensor is intended to be read by an ADC, some additional circuitry will be needed to shift the voltage into the positive range.

More details on both modules are covered in the Current Sensors article.
