LRST- T

Phase control with asymmetry detaction, delay on recovery.
• 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.
• Adjustable time delay from 0.1 to 10s on voltage recovery.
• LED indicates for: relay status, asymmetry and sequence.
