Quick overview

ATCR Series Current Transducers combine a sensing coil and a True RMS signal conditioner as a matched, factory calibrated set. The ATCR Series is designed to produce an analog 4-20 mA signal proportional to AC current up to 2000 amps. Coil opens to pass over the installed conductors. When connected to a controller or data logger, the sensor output is directly proportional to the primary current.

Applications
Monitor Large Machines
Monitoring resistive or inductive load to detect current.
Industry standard 4-20 mA output for connection to PLC or data loggers.

Flexible Coil Surrounds Conductors Without Disturbing Wiring
Install over bus bars, single or multiple conductors easily.
Fast response to changes in operating conditions.

True RMS Output: True RMS technology is accurate on distorted waveforms like VFD or phase angle-fired SC outputs.
Single Range: No chance of field range selection errors. Eliminates zero and span pots.
Isolation: Output is magnetically isolated from the input for safety. Eliminates insertion loss (voltage drop).
Designed to Meet UL508 and CE Requirements: Accepted worldwide.
Compact DIN-rail Mount Enclosure: Space saving 35mm wide enclosure mounts quickly.

AC current monitoring of large loads:
Loads drawing large amounts of power are connected to the supply using large wire or bus bar. Disconnecting
the conductors and threading them through a solid sensing ring or current transformer is difficult and time consuming. With this new design, the sensing is accomplished using a coil without a magnetically permeable
core. This allows the installer to pass the coil around the conductors after they are connected with a no need to disconnect. The coil is attached to a signal conditioning circuit, and the output signal is powered from the 24 VDC nominal loop voltage. Simple, easy to install, can monitor sinusoidal or distorted current wave forms at frequencies to 400 Hz, and designed for industrial uses.
