INQUIRY

SEQ3 ats dual power transfer switch power supply automatic conversion system is applicable to the dual power supply system with AC 50 / 60Hz, rated working voltage of 400V and rated working current of 63A to 250A.SEQ3 ats dual power transfer switch can realize the automatic transfer switch between common power supply (n) and double split and standby power supply (R) (also can be used for manual switching).

This dual power transfer switch is suitable for class I power system, especially for elevator, fire fighting, subway, hospital, post and telecommunications, communication, television station, industrial assembly line, ship and other emergency power departments, which can not be powered off. It is particularly important for the continuous power supply reliability of power supply.

SEQ3 ats dual power transfer switch has three working states: common power supply, double split (disconnected) and standby power supply.

SEQ3 ats dual power transfer switch Product feature

This type intelligent dual power automatic switchs the mechanical interlocking transmission, intelligent controller and other components. It has the integral style and split type with two kinds mechanism. Integral controller is equipped with a base and executing agencies;

Split type is intelligent controller installed in the panel User take the base by implementing agencies to install into the cabinet controller with an about 2m cables

□ Reliable mechanical interlock between the two circuit breakers and electrical interlockdevice,

Eliminate the two devices closing completely at the same time.

□ SCM intelligent controller used to control the core hardware is simple and powerful,

expansion of convenience,high reliability.

□ It has a short circuit, over load protection functions, over voltage,under voltage, loss phase

automatic transfer function and intelligent alarm function.

□ Automatic switching external parameters can be set free.

□ Operation of Intelligent motor protection.

□ The control circuit devices with fire, fire control center to a control signal into intelligent

controller. Two sets circuit breaker will enter a stating of breaking .

□ There is a computer network interface for achieving remote control four remote telemetry

functions.
