Product DescriptionWhat is dual power
automatic transfer switch?Dual-power
automatic transfer switch is microprocessor, which
is used to start and switch between grid power and grid power or
between grid power and generator power supply in power grid system.
It can supply power continuously. Series of dual power supply, when
the common use of sudden failure or power outage, through the dual
power automatic transfer switch, automatically put into
the standby power supply (under small load standby power supply can
also be supplied by generators), so that the equipment can still
operate normally. The most common are elevators, fire protection,
monitoring, lighting and so on.When the generator set is used as
emergency lighting power supply, the start-up time and power
conversion time of the generator should not exceed 15s. Double
power automatic switching switch should choose "city power -
generator conversion" special type.Dual-power
automatic transfer switch has the functions of short
circuit and overload protection, over-voltage, under-voltage,
phase-gap automatic conversion and intelligent alarm, automatic
conversion parameters can be set freely outside, and intelligent
protection of operating motor. When the fire control center gives a
control signal to the intelligent controller, two circuit breakers
enter the sub-unit. In the gate state, the computer network
interface is reserved for the realization of remote control, remote
adjustment, remote communication, remote measurement and other four
remote functions.Application1.CJQ3 series Automatic transfer switch
mainly used for distribution or electromotor network, which under
voltage 400V, rated voltage DC 220V, Rated current 63A-3200A.2.Main
power and standby power or mutual standby power change over system
or city power and generator group overload switch-over. At the same
time, it can operated under un-frequency on and off circuit act as
disconnector.Widely used at the field of important power supply
site, which transport, distribution power supply system and
automatization system. For fire
protection,hospital,bank,building,etc, where doesn't allow power
off.Product Parameters Conventional thermal
