EUS VOLTAGE CONTROL WITHOUT MEMORY

Control of AC / DC voltage without memory

When the value of the controlled voltage, AC or DC, reaches the threshold

Unit power-up

Ue displayed on the front face, the output relay changes state at the end of
a time delay T which can be set on the front face at between and 3 s.

Threshold Ue

Hysteresis

Once the voltage drops below 5 to 50% of the threshold hysteresis , the

Controlled voltage
output relay changes state again instantly. Changing the hysteresis on the

UPPER function
front face does not therefore modify the value of the preset threshold. Control of AC / DC voltage with memory

Hysteresis Threshold Ue

Controlled voltage

When the value of the controlled voltage, AC or DC, reaches the threshold Ue displayed on the front face, the output relay changes state at the end of a time delay T which can be set on the front face at between and 3 s,

EUSF SERIES

Unit power-up

The EUSF window threshold relay monitors an electrical voltage which acts
as its own power supply simplified wiring . When the value of the controlled voltage, AC or DC, goes outside the window, the output relay deenergises at the end of a time delay T which can be set on the front face at between
