Monitoring voltage relay HRN-33
Supply and monitored voltage in range AC 48…276 V, 1 x output for Umax and Umin adjustable level serves to control supply voltage for appliances sensitive to supply tolerance, protection of the device against under/over voltage.
HRN-33
- monitors voltage in range AC 48…276V
- U max and U min can be monitored independently
Adjustable time delay for all types is 0…10s (to eliminate short voltage drops or peaks)
Voltage Umin adjusted as % of Umax
3-state indication - LEDs indicating normal state and 2 fault states
Supply from monitored voltage (monitors level of its own supply)
1-MODULE, DIN rail mounting
