Voltage monitoring relay in
1P - AC/DC HRN-42

DESCRIPTION

• Relay designed for monitoring DC and AC voltage in three ranges.
• The relay controls the size of the voltage in two independent levels (Umin, Umax).
• Setting the monitored level Umax (in % of range).
• Setting the monitored level Umin (in % of range - for HRN-42 -function WINDOW), (in % of the set upper limit - for HRN-41 - function HYSTERESIS).
• Function of second relay (independently/in parallel).
• Adjustable delay for eliminating short-term outages and surges for every level independently.
• Galvanically separated power supply from monitoring inputs.
• Output contact for each monitored voltage level.
