Multifunctional monitoring voltage relay - HRN-31, HRN-32/2, HRN-36, HRN-39

Description

• Used to monitor the size of DC or AC voltage in single-phase circuits
• Powered from a monitored circuit
• Measurement of monitored voltage TRUE RMS
• Monitors the exceeded upper limit of stress (Umax) and falling below the lower limit of stress (Umin) – according to the selected function
• Continuous adjustment of both voltage limits – the lower level Umin is set in % of the upper level Umax
• Adjustable reaction delay (to eliminate short-term voltage peaks)
• Option to select functions with error state memory (Latch)
