Various Types:

a) Conventional Current Transformer

b) Hall Effect Current Transformer


PCB mountable current sensor up to 25 Amps

Measure AC currents up to 50 kHz

EN 50178, IEC 61010-1
Principle of Hall Effect:

When a current-carrying conductor is placed into a magnetic field, a voltage is generated perpendicular to both the current and the field. This principle is known as the Hall Effect.

Advantages of Hall Effect Current Transformer:

a) Measure AC currents up to 50 kHz.

b) Sensor measures AC & DC currents

c) Linear output over the entire range (better than 1% accuracy from 100 mA to 25 amps)

d) High speed sensing

e) Immune to most types of external disturbance.

f) Power consumption is very low.

g) Works on a wide supply voltage.
