Product Detailed
1.Compact size,single structure,beautiful outlook; 2.Convenient operation and long operating life; 3.3,4P supplied;

Product introduction:

     JATS(ATS) series automatic transfer switch is one new new ATS of our company devloped by the microcomputer control technology.This series ATS is settleed AM2,DZ65 circuit breaker circuit as the executive element,and along with plied in the important places not allowed power off.To meet actual demand,three different operation methods are available such as automatic entry automatic entry non automatic reset and commutative standby.

Main features:

Three available operation methods:1.Automatic entry automatic reset2.Automatic entry non automatic reset3.Commutative standy

(1)Three steady operating positions:1.The grid power supply is making,the standy power supply is breaking.2.The grid power supply is breaking,the standy power supply is making.3.The grid power supply is breaking,the standy power supply is breaking.Compact size,single structure,beautiful outlook,33-630A available,convenient operation and long operating life,2,3,4P can be supplied.The transfer is drived by single motor,single structure,reliable transfer,no noise and small wallop.The switch is with electromechanical interlock protection,which can ensure the two power supplies

working normally,no disturbance.The switch can be along with load automatic transfer,on urgent situation,it can be transferred by


(2)Advantages comparative to other products:1.The breaking capacity of the control protectiing fuse is 50KA,which increases the distribution safety.2.Thereis interlock between manual and automatic operation,this can avoid the manual operation on the automatic operation.3.When the executive handle of circuit breaker,the contact is felt or the load is in problem (overload,short circuit),the ATS do not transfer,this is called the real electromechanical interlock.4.The driving mechanism of MCB type ATS is changed from fork type to concave type.which solve

the problem of the break of the long handle type MCB and the non-synchronization of MCB manking etc.thus strengthen the function of fast making and breaking,and enhance the mechanical life.5.The wrong wire connection indication can be supplied.When the phase wire and zero wire is connected wrong,the sound-photo device will alarm,it ensures the reliability.

JATS and DZ65series:

Note:1.To the nonstandard products,the detailed requirement should be noted.Eg.The type of fire protection signal(constant voltage DC24V/impulse DC 24V/constant voltage AC220V/impulse AC 220V.Without note,it'll be considered DC24V.)the type, quantity of no power feedback signal(the default value is the feedback signal in the position of No.1 group.)         2.If there's special request of of the executive circuit breaker,tripper,it should be noted.  


AC-33B(CB products)/AC-23B(PC products)Service condition:The altitude of installation site not higher than 2000mAmbient temperature:-25' C~55' C,relative humidy less than 95% at 55' C.Pollution level:III

Electrical performance &function:

      JATS(ATS) automatic transfer switch decide if it should turn from one power supply to the other power supply according to its voltage status and operation mode set by users.The function depend on its controller which consists of A type and B type.Please refer its main functions to table 1.

Table 1 functions of controller in JATS(ATS) automatic transfer switch:

Note:1) If working voltage is the same as power voltage, the common power supply and standby power supply can supply power directly. If not, it must use BC or equivalent isolation transformer.

          2) Under the situation of handle operation, if the control circuit of electrical manipulating device is open, automatic controlling function will be invalid.

          3) On conditions both common power supply and standby power supply are normal, if common power supply is malfunction and automatically transfer to standby power supply(transfer time delay adjustable); when the common power supply returns to normal, it will automatically return(return time delay adjustable).

          4) Under the situation both common power supply and standy power supply are normal and common power supply is working, if common power supply is malfunction and automatically transfer to standby power supply, controller will stop transferring.Even if common power supply returns to normal, switch will not return. Please press reset pushbutton,controller returns to normal.

          5) Under the situation both common power supply and standby power supply are normal, to get through electricity(or reset), the common power supply will work prior.  If the working power has some malfunction during operation and automatically transfer to another power supply(B type switching transfer time delay adjustable), both power supply will have the same priority and will be standby power supply of each other.
