Measures & scans 3 phase voltage supply and display the line voltage or Line to Neutral Voltage. It also monitors the Under & Over voltage conditions & compare with the Programmed Preset trip levels. In case, it exceeds the preset limits it de-energizes an output relay. The Scanners can be Manually reset.
Features:
· Digital 3 phase voltage readout. · Scan time of 5 sec each · Preset under voltage trip( 75% - 95%) adjustable. · Preset over voltage trip( 105% - 120% ) adjustable. · Energizing time delay( 2- 5 sec) · 1 CO( 2 CO) output relay rated 5A/230V AC. · Manual reset · DIN panel cutout flush mounted enclosure.
Application Areas:
Generator panels AMF controls panels UPS control panels Power distribution panel
