1. Application
Over Voltage And Under Voltage Protective Device With
Auto-Reclosing Function (OUPA) is an intelligent protect
integrated with over-voltage protector, under-voltage
protector and over-current protector. In case of over-
voltage fault, under-voltage fault or over-current fault in
line, this product can instantly power off to prevent
electrical equipment from being burnt. The over-voltage,
under-voltage and over-current values of this product car
all be set up by yourself and can be adjusted on the basis c
local practical condition.
II. Product features
2.1 In case of over-voltage fault, under-voltage fault or
over-current fault in single phase line, the product can
power off the line and can automatically restore connecting
the line over a time delay after voltage or current of the line
is recovered to normal condition.
2.2 In case of transient over voltage in line, the product can
protect the equipment from false operation.
2.3 In case that the line subjects to unstable Voltage or
sudden power-off and power-on due to loosened
connection and other fault, the product will disconnect the
line.
2.4 When fault voltage of the line reaches the peak, the
product itself will not be damaged.
