LPRC/2 Phase Failure, Phase Sequence, Under and Over Voltage plus Time Delay


Broyce Controls L-Series signal conditioners use a QR barcode marking method allowing direct access to all technical data sheets, ensuring correct information is always at your finger tips!

Features and Benefits


Compact 17.5 mm DIN Rail housing

Microprocessor based

True R.M.S. monitoring measuring phase to phase (three wire) or phase to neutral (4-wire) voltages

Selectable nominal voltages to suit most popular three wire or 4-wire supply voltages

Monitors own supply and detects if one or more phases exceed the set Under or Over voltage trip levels

Detects incorrect phase sequence, phase loss and neutral loss1

Adjustments for Under and Over voltage trip levels

Adjustment for time delay

Independent relay outputs - Under voltage monitoring / Over voltage monitoring

2 x SPDT relay output 5A

Green LED indication for supply status

Individual Red LED indication for both relay statuses
