Open, Closed and Soft Load Closed Transition
The ATS 1200 brings advanced digital control technology to a free standing, feature-rich package.

ATS Features

• Available in multiple sizes: 600A to 1200A (Low Voltage 208V-600V)
• UL-1008 and UL-891 listed device
• Available as Service Entrance Equipment*
• System control logic provided by the Generator Power Control™ (GPC), or “Gold Box,” which includes a full complement of protective relays
• 4 line, 20 character vacuum fluorescent display and status LEDs (inside door on NEMA 3R enclosures)
• Two front panel switches, an Auto/Off/Run switch and a System Reset switch
• Five front panel annunciators: Normal Source Available, Emergency Source Available, Normal Breaker Closed, Emergency Breaker Closed and Alarm
• Load/No Load Testing for system reliability assurance
• Direct engine control & monitoring
• Integrated load shedding capability*
• High withstand, totally enclosed switches
• Molded case switch power contact assemblies
• Multiple system start options:
  • kW demand level - automatically peak shaves when facility demand level exceeds a pre-determined set point*
  • Auto-schedule (time-based) - uses a timer to peak shave at regularly scheduled intervals*
  • Remote - allows operators to initiate remote soft load transfer for specific events *
  • Local operator interface - all operating modes are available through the local display interface

• Integrated Multifunction Digital Controller
• Standard Communications Protocols
• Flexible Development Environment
• Protective Relay Module
• ATS Module
• Synchronizer Module
• Remote monitoring, control, and alarming is available through GPC protocols via the Virtual Maintenance Monitor™ and the Virtual Power Plant™ software products*

• The ATS 1200 is capable of automatically performing a soft load transfer between the utility and generator power sources. It allows the generator to run in parallel with the utility, if needed.
• Provides reliable and versatile systems monitoring and interaction with all transfer switch functions. The ATS 1200 offers a wide array of options for customer
  design flexibility.
• Incorporates high withstand drawout breakers, totally enclosed for maximum arc suppression and isolation during power transfer.
• Permits true quick-break, quick-make manual operation under full load. Operation under load is completely safe to personnel and equipment.
• Provides safe, positive disconnection for electrical isolation of the logic circuits for maintenance or manual operation.
• Application modes and settings are easily adjusted through local menu driven user panel and via optional remote software interface.
• Modular design eases preventive maintenance and adapting to new
  application requirements.
• Closed transition eliminates outages during intentional transfer.

Emergency Standby
During a sudden utility outage, the generator automatically starts, increases to rated frequency and voltage, and transfers power to the facility through open transition mode generation systems.

Peak Shaving
By operating a generator in parallel with the utility during high demand periods and allowing the generators to supply a fixed power output, businesses can realize significant energy savings.

Interruptible Rate
By participating in interruptible rate programs, businesses can recover sizable portions of their utility bills by transferring all or part of their electrical load to an on-site generator.

Export-to-Utility
In import-export mode, the generator soft loads to a user-adjustable kW level. The power flow to the utility remains constant while the generator output fluctuates to meet the requirements of the load. Depending on utility requirements, this application might require additional metering equipment on the utility feed.

• Open Transition
• Closed Transition (<100ms)
