THE ATS LINEUP
Peace of mind starts here.
Bridging the gap between loss of utility and standby power is no small task. KOHLER® automatic transfer switches (ATS) are designed to meet that challenge, distributing power to feed the critical loads of your facility.
Every transfer switch needs a controller to ensure transfer of power from utility to generator and back again. KOHLER Decision-Maker® MPAC® controllers offer clear choices in matching function to application.
STANDARD FEATURES
- Multiple Applications: Find the perfect option. KOHLER automatic transfer switches are available in standard, bypass-isolation and service-entrance configurations with open, closed and programmed transition operating modes, from 30 to 4000 amps.
- Seamless System Integration: Everything works together. KOHLER transfer switches are designed to interface perfectly with KOHLER generators and paralleling switchgear.
- Advanced Communications: Every transfer switch comes fully loaded with the technology to do the job. Ethernet and Modbus communications capabilities are available.
- Certified Packages: Transfer switches are UL-listed and have CSA and IBC certifications available.
The document shows images of two large Kohler Automatic Transfer Switch cabinets with digital displays labeled 'KOHLER. Decision-Maker MPAC 1500' and 'KOHLER. Decision-Maker MPAC 1200'. It also shows images of a Standard ATS, a Service-Entrance ATS, and a Bypass-Isolation ATS.
CUSTOM CONFIGURATION
The chart tells the story. You can custom configure switches by choosing the exact components needed. This standard process allows Kohler to provide the correct switch for your application with delivery in the shortest amount of time. Each letter and numeral corresponds to a specific element of the ATS. Here's an example.

DECISION-MAKER MPAC CONTROLLERS
Two options. Two solutions.
The document shows images of the MPAC1200 and MPAC1500 controller displays, featuring similar interfaces with voltage readings and status indicators.
MPAC1200
A customizable solution for your specific application. The ATS1200 gives you full control of system behavior including extended I/O to customize your needs.
MPAC1500
When you need to manage your loads, use your system as a prime power application or have a backup for your backup (i.e., a three-source system); this controller gets the job done.
