Characteristics
• it 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
diff erence - see graph 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 (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
