JATS series automatic transfer switch

Product introduction

JATS series automatic transfer switch is one new ATS of our company developed by the microcomputer control technology. This series ATS is settled AM2, DZ65 circuit breaker as the executive element, and along with the mechanotronics, the new control mechanism with electromechanical double interlock, which is especially applied in the important places not allowed power off. To meet actual demand, three different operation methods are available such as automatic entry automatic reset, automatic entry non automatic reset and commutative standby.

Main features:
Three available operation methods
1. Automatic entry automatic reset
2.Automatic entry non automatic reset
3.Commutative standby
Three steady operating positions
1. The grid power supply is making, the standby power supply is breaking.
2. The grid power supply is breaking, the standby power supply is making.
3. The grid power supply is breaking, the standby 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 handle.
Advantages comparative to other products:
1.The breaking capacity of the control protecting fuse is 50KA, which increases the distribution safety.
2.Theres interlock between manual and automatic operation, this can avoid the manual operation on the automatic operation.
3. When the executive handle of circuit breaker is broken, the contact is felted 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 making 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
non-standard product Standard product
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, itll 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 theres special request of the executive circuit breaker, tripper, it should be noted.

Electrical perfomance & function
JATS 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 functions depend on its controller which consists of A type and B type. Please refer its main functions to table 1(Next page)

Table 1 functions of controller in JATS 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 (
