ATP SERIES AC Current Transducers
AC Current Transducers
ATP Series Powered AC Current Transducers sense currents
from 0–200 A and provide a proportional analog VDC or
mA output. Powered by 120 VAC or 24 VAC/VDC, the
ATP Series Powered AC Current Transducers eliminate the
need for costly power supplies or voltage rectifiers inside the
control panel. Designed for motor control applications with
standard sinusoidal waveforms, the ATP Series Powered AC
Current Transducers feature user-selectable input ranges, a
choice of outputs and split-core or solid-core enclosures.
AC Current Transducer Applications
AC Current Transducer Features
Commercial and Industrial Motor Control Centers
•120 VAC power supply option allows for powering off
of readily available supplies; ideal for pumping, water/
wastewater, boiler and other industrial applications.
•Eliminates the need for 24 VDC power supply or AC
rectifiers within the control panel; saves space, material
and labor associated with power supplies.
Fast, Accurate RMS Measurement
•Unique ‘average responding’ algorithm provides RMS
output on pure sine wave and constant speed loads,
offering improved accuracy over two-piece solutions.
Heater Failure Detection
Isolation Output
•Output is magnetically isolated from the input for
enhanced safety and elimination of insertion losses.
Jumper Selectable Input Ranges
•Each unit has multiple input range capability and can be
used for a variety of applications, reducing the need for
separate models.
