ONLITE central EPD 2
Art.-Nr: 24 161 074
1. Description
Undervoltage monitor for three-phase mains (each phase towards
neutral) provided with invariable preset threshold, preset hysteresis
and integrated test button.
The device can also be used to monitor a single phase. Then,
the unused entries have to be connected to a connected phase,
otherwise the device would functionally indicate the missing
voltage.
If the consumer causes an inverse voltage that is higher then
the preset threshold, the device will not release an error signal.
When actuating the test button the output relay will drop out.
The output relay R is activated (red LED lis lighting) when the
measured voltage of all connected phases exceeds the preset
value including hysteresis. When the voltage of one of the
connected phases falls below the preset value, the output relay
will drop out again (red LED does not light).
2. Declaration of Conformity
The device was tested according to the applicable standards.
Conformity was proofed. The declaration of conformity is available
on the Zumtobel Homepage.
