MONITORING RELAY VOLTAGE HRN-41-UNI

The relay is designed to monitor AC or DC voltage in three different ranges. It monitors voltage on two independent levels (Umin, Umax). The upper limit is set (Umax) as a percentage of the range. The lower limit setting (Umin): as a percentage of the upper limit (HRN-41, function HYSTERESIS) or as a percentage of the range (HRN-42 function WINDOW). Output contact operation can be selected (independently/simultaneously). Adjustable time delay for both levels (eliminates short-term voltage spikes and dips). Galvanically isolated changeover contact for each monitored voltage level. Technical specifications: Supply voltage: 24-240 V AC/DC. Monitored voltage ranges (selected by connection): 10-50 VAC/DC (C-B1), 32-160 VAC/DC (C-B2), and 100-500 VAC/DC (C-B3). Contact: 2 x changeover contacts 16A. Breaking capacity: 4000 VA/AC1, 384 W/DC. Breaking voltage: 250 V AC and 24 V DC. Width: 3 modules This product description is an automated translation of the original Finnish description.
