NK ATP4-005-120-FL - AC Current Transducer, ATP/ATPR-FL Series

• Measurement = Average Responding
• Full scale range = 1000, 1300, 2000 A
• Output signal = 0-5 VDC
• Power supply = 120 VAC/DC
• Case style = solid-core

ATP/ATPR-FL Series AC-Current Transducers are large-format solid-core transducers designed for high current applications from 200 A to 2000 A. Powered by 120 VAC or 24 VAC/DC, the ATP/ATPR-FL Series takes advantage of available power supplies and eliminates the need for costly control power transformers. Options include average responding and True RMS versions, 0-5/10 VDC or 4-20 mA analog outputs and switch-selectable input ranges.

AC Current Transducer Applications

Commercial and Industrial MCC’s

• Fits conveniently in motor control centers, senses current on industrial motors and provides analog inputs back to PLC or controller.

VFD or SCR Controlled Loads, Electronic Ballasts

• Helpful in monitoring VFD-controlled motors to provide operational status. Provides accurate measurement of ballast input power and phase angle fired SCRs.

Large Pumping Applications

• Ideal for proof-of-flow in water/wastewater, boiler and other industrial pumping applications 150 HP and over. 120 VAC/DC or 24 VAC/DC supply options allow for powering off of readily available supply, eliminating need for CPTs.

Power Distribution Centers (PDCs)

• Monitors current output on commercial generation equipment and serves as a current input for use in power consumption calculations.

AC Current Transducer Features

Large Aperture

• Accommodates large conductors or wire bundles.

Select the Right Output

• True RMS technology is accurate on distorted waveforms like those associated with VFD or SCR outputs.
• Average Responding for use with linear, sinusoidal waveforms.

Jumper-selectable Ranges

• Reduces inventory.
• Eliminates zero and span pots.

Isolation

• Output is magnetically isolated from the input for safety.
• Eliminates insertion loss (voltage drop).

Designed for UL/cUL, CE Approval

• Accepted worldwide.

AC Current Transducer Connections

Notes: Terminals are deadfront captive screw terminals.
