Issue
Certain applications call for a simple device that can detect phase loss and notify a user of the alarm.
Product Line
EM3502(A), EM3550(A), EM3555, EM3560(A)
Environment
Power Monitoring, Basic Energy metering, Phase Monitoring
Cause
Application calls for a device that can alarm on phase loss without complicated programming.
Resolution
EM3500 series meters contain a dedicated phase loss alarm. This is in the form of a normally closed (NC) contact as well as an LED indicator on the front display.
NC contact is 30VA/C D/C MAx
This alarm output is in addition to any additional energy pulsing or digital outputs supplied with the meter.
