LRST-20

Phase control with asymmetry detection 2 c/o relay output

• Monitors its own supply voltage.
• Detects phase failure, phase sequence, and phase asymmetry.
• Detects loss of neutral.
• Detect phase failure with regenerated voltage present (back EMF).
• Asymmetry rate from 5 to 20% of Un
• Measuring voltage with neutral.
• LED indicates for: relay status, asymmetry, and sequence.
• 2 c/o output relay
