Voltage monitoring time delay relay
ELKO
* serves to control supply voltage for appliances sensitive to supply tolerance, protection of the device against under/over voltage
* HRN-3x is band voltage relay, HRN-6x is over/under voltage relay. For difference - pes see grach of function
* HRN-33, HRN-63
- monitors voltage in range AC 48 - 276 V
- U max and U min can be monitored independently
* HRN-34, HRN-64
- like HRN-33, but voltage range is DC 6 - 30 V
- monitoring of battery circuits (12, 24 V)
* HRN-35
- like HRN-33, but independent output relays for each voltage level
- switching of other loads possible
* HRN-37, HRN-67
- like HRN-33, monitors voltage in range AC 24 -150 V
- it is possible to monitor level of overvoltage and undervoltage independently
* adjustable time delay for all types is 0 - 10 s (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
