Automatic Transfer Switch (ATS) is used which operation voltage is no more than 660VAC, and may transfer with load. The ATS rated current series is40A, 63A, 80A,125A, 160A, 250A, 400A, 630A, 800A,1000A,1250A,1600A,2000A, be divided up two types with 3 poles and 4 poles. The ATS of 40-125A is defined with "N"; 160-400 is defined with "T"; 630A-2000A is defined with "M".
SGQ Automatic Transfer Switch (ATS) is used in conditions from AC660V 50/60HZ to DC250V which under electromagnetism drive structure and two-stage PC class type. SGQ ATS can make fast load transfer (transfer time ≤80ms) of two ways power supply. Also ATS can be widely used in high buildings, post, telecommunications, coal mines, ships, industry, health care, military facilities and so on. 2-way power supply can be grid, auto start genset, storage battery and etc..
STRUCTURE AND CHARACTERISTICS
SGQ Automatic Transfer Switch (ATS) adopts structure of magnet coil driving and interlocking of electric and mechanical. The structure of major loop contact terminal consists of one dynamic and two static contacts. And the dynamic contact is in "V" type design, in order to ensure there is no short circuit of the 2-way power supply. "N" and "T" type use structure of double coils while "M" type use single coil operation. The coil only energized while it is transferred which can extremely extend the using life of switch. The control power of coil is supplied from priority AC/DC power, so there is no use to add another control power. The switch has electrical and mechanical close indication by itself and also offers 2 way NO/NC voltage free auxiliary contacts at the same time.
