1. Application
Adjustable voltage,current and leakage protective device with
kilowatt-hour meter is an intelligent protector integrated with
over-voltage protector, under-voltage protector,over-current
protector and leakage protector. In case of over-voltage fault,
under-voltage fault,over-current fault or leakage in line, this
product can instantly power off to prevent electrical equipment
from being burnt. The over-voltage, under-voltage,over-current
and leakage protection values of this product can all be set up
by yourself and can be adiusted on the basis of local practica
condition.
ll. Product features
2.1 In case of over-voltage fault, under-voltage fault, over-
current fault or leakage 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.
2.5 The protector can display kilowatt-hour, kW and power factor.
