AC Current Switches, Transducers and Indicator

Overview

The ACUAMP series of AC current
sensors is a family of high-performance
current sensors offering outstanding
features, flexibility, and durability at an
incredible price. Choose from a wide
selection of current transducers, switches
and indicators, all designed in a rugged
industry-standard feed-through package,
including both fixed core and split core
models.

ACT and ACS models have multiple input
ranges (set by movable jumpers) for
maximum flexibility across many current
ratings. The current transducer output
choices include 4 to 20mA, 24 VDC loop­powered, and 0 to 10 volt self-powered
analog outputs. The Current Switch outputs
are isolated solid state switches and are
available in Normally Open and Normally
Closed configurations.

A unit featuring field adjustable time delay
is also offered in the Current Switch series.
The ACL1 Current Indicator senses AC
current ranging from 0.5 to 100 A and
requires no power for the indicating LED.

All models are panel-mountable; conve­nient DIN-rail adapter accessories are
available. Use the Selection Guide to find
the best sensor for your requirements.

AC Current Sensors, Switches and Transducers Application Guide

Pump Jam & Suction Loss Protection

Crusher/Grinder/Shredder Motor Interlocks

Electric Motor Load Status

Pump Load Monitoring

The performance of size reduction equipment like crushers or
grinders can be optimized by controlling the in-feed in order to

• Help prevent jamming

• improve the uniformity of the resultant product

• Enhance overall production efficiency

Application Guide

ACUAMP current sensors are a great fit

for many applications including material
handling, fan and pump applications, and
heating systems. With current transducers,
current switches and current indicators,
this sensor family gives you valuable data

for processes ranging from monitoring
loads to preventive maintenance. Models
with the ability to read True RMS non-sinu­soidal waveforms make it easy to monitor
applications using variable frequency
drives.

Use the application examples to help
choose the best sensor model for your
application.

ACT current transducers combine a current
transformer and signal conditioner into a
single package. The ACT series has
jumper-selectable current input ranges
and industry standard 4-20 mA or
0-10 VDC outputs. The ACT series is
designed for application on ‘linear’ or
sinusoidal AC loads and is compatible with
most PLCs, data loggers and SCADA
systems. Full-scale input ranges are user­selectable from 2A to 2000A. This series is
available in split-core or fixed-core
models.

Applications

Automation Systems

• Analog current reading for remote
monitoring and software alarms

Data Loggers

• Self-powered transducer helps conserve
data logger batteries

• Split-core enclosures make using portable
data loggers easy

Panel Meters

• Simple connection displays power
consumption or other motor status

Features

• Five-year warranty

• 4-20 mA or 0-10 VDC outputs

• Use up to 14 AWG copper wire

• Factory matched and calibrated single
piece transducer is more accurate than
traditional two-piece field installed
products.

• Average responding algorithm gives an
RMS output on pure sine waves; perfect for
constant speed (linear) loads or ON/OFF
loads.

• Selectable input ranges allow end-users to
tailor sensing ranges and improves the
odds of having the right range for the job.

• Output is magnetically isolated from the
input for safety and to eliminate voltage
drop.

• Built-in feet with optional 35 mm DIN rail
adapter available.
