3-Phase Monitor
Detects Phase Loss, Low Voltage,
Phase Reversal
Automatic or Manual Reset
DPDT Relay Output
DESCRIPTION
The Model 2522 continuously monitors 3-phase power
lines for abnormal conditions. When properly adjusted, the
Model 2522 will detect phase loss on a loaded motor even
when regenerated voltage is present.
This unit consists of a solid-state voltage and phase-angle
sensing circuit, driving an electromechanical relay with
DPDT contacts. When correct voltage and phase rotation
are applied, the internal relay will energize.
condition will de-energize the relay.
corrected the Model 2522 will reset.
Both automatic and manual reset versions are available.
The Model 2522 does not require a neutral connection, and
