Over- and undervoltage monitoring
ON-or OFF-delay configurable
Open- or closed circuit principle configurable
Latching function configurable
Thresholds for Umin and Umax adjustable
Fixed hysteresis of 5%
Tripping delay TV adjustable 0; 0.1-30s
1x2 c/o contacts (common signal) or 2x1 c/o contact (separate signals for Umin and Umax)
