Original Genuine ATS SGQ250A SmartGen Generator Set Dual Power Automatic Transfer Switch
 

Product Overview:
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.

Key Product Features

  1. Genuine SmartGen Original PC-Class ATS, Strict Factory Aging Test
    Every original SGQ250A undergoes withstand voltage, load conduction, mechanical life and interlock safety full test before delivery, silver alloy contacts effectively avoid contact ablation, poor conduction and heating failure caused by frequent switching, with stable long-term operation reliability.
     
  2. Electrical + Mechanical Double Interlock, Zero Risk of Dual Power Short Circuit
    Unique V-type moving contact structure, together with electrical interlock circuit, strictly prevents mains and generator two power sources from closing at the same time, completely eliminates large-scale short-circuit safety accidents of power distribution system.
     
  3. Fast Switching ≤80ms, Guarantee Uninterrupted Power Supply For Important Loads
    Ultra-short switching time avoids production line shutdown, precision equipment shutdown data loss, medical equipment power failure safety hazards, fully meets the power supply requirements of first-class important loads.
     
  4. Built-In Auxiliary Feedback Contacts, Perfectly Linkage With SmartGen Controllers
    Real-time feedback switch main power/standby power closing status to the generator controller, realize automatic start-stop, fault alarm and intelligent linkage of the whole power supply system, convenient for remote monitoring and centralized management.
     
  5. Wide Voltage & Wide Temperature Industrial Design, Strong Environmental Adaptability
    Adapts to 50/60Hz global mainstream power frequency, works stably in high-temperature, dusty, humid and low-temperature environments, suitable for outdoor unattended distribution stations, ship and mining harsh working conditions.
     
  6. Modular Standard Structure, Easy Cabinet Installation & Maintenance
    Standard size design, convenient for installation inside various generator control cabinets and power distribution cabinets; manual test button is reserved, convenient for regular on-site maintenance, debugging and fault inspection.
     

Common Equipment Failures Solved

  • Ordinary CB-level ATS has poor interlock reliability, easy to cause dual-power mis-closing short circuit, resulting in power distribution system tripping and equipment burnout
  • Inferior switch contacts are easy to heat, ablate and conduct poorly, leading to voltage drop, load unable to work normally
  • No auxiliary feedback signal, cannot realize automatic linkage with the generator controller, requiring manual on-site operation
  • Slow switching time leads to precision equipment shutdown, production line shutdown and huge economic losses
  • Non-original ATS has inconsistent installation size and control logic, difficult to match SmartGen automatic control system, high transformation cost
