VOLTAGE CONTROL RELAY
UL cUL listed
•2 Product Types – .2 to 60 V and 10 to 600 V
• Selectable Under or Over Voltage Modes
• Space Saving 22.5mm Wide Enclosure
• DIN-Rail / Surface Mount
TWO PRODUCT TYPES: EUL (.2 TO 60V) AND EUH (10 TO 600V)
PROVIDE SELECTABLE OVER OR UNDER VOLTAGE CONTROL.
MODE OF OPERATION
VOLTAGE CONTROL WITHOUT MEMORY
Control of AC / DC voltage without memory
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 0.1 and 3 s.
Once the voltage drops below 5 to 50% of the threshold (hysteresis),
the output relay changes state again instantly. Changing the hysteresis
on the front face does not therefore modify the value of the preset
Threshold Ue
