Description
Applications:
Monitoring of three-phase power supplies for undervoltage and switching to safety power supplies.
For systems according to:
· DIN VDE 0108-100 (safety lighting)
· DIN VDE 0100-718 (structural systems for general assembly)
When the measuring voltage is applied to the measuring inputs L1-L2-L3 and the line supply is error-free, the relay switches to the good state if the voltage for 1 min. no longer falls below the undervoltage threshold.
During this waiting time of 1min, the yellow LED flashes. After detecting undervoltage at one or more phases for more than 0.5 s, the relay will drop.
The undervoltage relay measures the arithmetic mean value of the 3 phase voltages against N.
· according to IEC/EN 60255-1
· for systems according to DIN VDE 0100-718 and DIN VDE 0108-100 (following standard of DIN VDE 0108 )
· Detection of undervoltage in three-phase networks
· without separate auxiliary voltage (Generated from the measuring voltage of all 3 phases)
· LED display for operating voltage and contact position
· for any phase sequence
· Closed-circuit principle (output relay not activated in the event of a fault)
· 2 changeover contacts
· with fixed time delay of 0.5 s for error message
· with fixed time delay of 1min for switching back to good status
· with fixed response value at 195.5 V AC
· optionally with test button for function check
· 17.5 mm width
