AT/ATR-TH Series AC Current Transducers

The AT/ATR-TH Series Current Transducers are the latest innovation for monitoring three-phase loads, motors, machines or buildings. The large triple-aperture solid-core design allows for a quick and easy installation. Just thread the conductors through the sensing windows (apertures) and reconnect on the other side. The transducer outputs are powered from an excitation voltage of 24 VAC or DC, or optionally 120 VAC, isolated from the monitored circuit. Three outputs are proportional to the AC current in each phase and a fourth represents the average of the three. Each are available at any time. The sensor mounts on a back panel or a DIN rail and is designed to accommodate wire sizes for loads up to 200 amps.

Current Transducer Applications

Monitor Large Machines

Detect over or under current conditions before they cause break downs or interlock one process with another.

Water Delivery and Treatment

Detect open discharge lines.
Sense clogged filters or blocked intake to pumps.
Measure increased current to show failing bearings or pump impeller cavitation.

Generators

Shed noncritical loads when demand reaches a set level.

Load Imbalance

Monitor motor current draw which should be nearly equal in all three phases. A difference of 10% signifies trouble.

Current Transducer Features

Analog Signal Proportional to AC Current

Both average responding and True RMS models available.
Compatible with most automation and control systems.
One output represents the current in each phase. A fourth produces a signal proportional to the average of the current in all three phases.

Externally Powered

Simple and reliable connection.

Factory Calibrated and Warranted For Five Years

Choice of ranges : 0-10 to 0-200 amps.
Designed for longest life and reliability.

Solid-core Case

Sensing windows provide ample space for single or multiple conductors per phase.

DIN Rail or Panel Mount

Snap onto DIN rail or attach with screws to a panel for secure mounting.

Designed to meet UL, cUL and CE

Accepted worldwide.
