CMG Series

The CMG Series is a

self powered

Current Monitor/Relay that is used

to detect the presence of AC current. When the monitored current

exceeds the trip point for longer than 400 mSec., the internal relay

energizes (Pick-up). When the monitored current drops below the trip

point for longer than 50 mSec., the internal relay de-energizes (Drop-

out). No physical connection is required as the line to be monitored is

magnetically coupled by passing the conductor through the protrud-

ing Current Transformer of the monitor. No external supply is needed

to power the monitor.

OPERATION

The current trip point specified is with one turn through the transformer.

Each time the number of turns through the transformer doubles, the trip

point effectively halves. Example: CMG-0100-20 will trip at 20 amps with

one turn passing through the transformer. By placing two turns through the

transformer, the relay will trip at 10 amps. Likewise, four turns will cause the

relay to trip at 5 amps. (See below)

• No physical connection to the AC line that is being monitored

• Magnetically coupled by passing supply line through

protruding Current Transformer

• Withstands 400 Ampere-Turns Continuous

• No supply voltage required

• Will operate on 24, 120, 240 or 480 VAC lines

• 1/4" Quick Disconnect Terminals
