Time-delay devices for undervoltage releases
Undervoltage releases can also be equipped with external, electronic time-delay control
devices which prevent unintentional tripping in response to brief voltage dips during periods
of disrupted operation.
Time-delay device for UVR with fixed delay setting
The simple time-delay device with fixed delay setting is available for the following voltages:
●
230 V AC and 230 V DC
●
24 V DC
The default delay time is >100 ms, as supplied, but can be extended by the customer with
the addition of customer-supplied supplementary capacitors:
As an alternative to screw mounting, the device can also be mounted on a 35 mm DIN rail.
You can find a circuit diagram for the time-delay device in chapter Circuit diagrams
