CUMMINS TS1311 MK11 Used Working PowerCommand ATS Controller

Product Overview

The Cummins PowerCommand® TS1311 (MK11) is a sophisticated Automatic Transfer Switch (ATS) Controller designed for high-reliability emergency power applications. This microprocessor-based control system is responsible for monitoring both the utility (source 1) and generator (source 2) power supplies. It automatically triggers the transfer of electrical loads to ensure continuous operation during power failures and manages the re-transfer once utility power is stabilized. This Used Working unit is a critical replacement part for Cummins PowerCommand transfer switches, offering advanced diagnostics, programmable timers, and seamless integration with Cummins generator sets.

Key Features

• Microprocessor Intelligence: Provides precise control and monitoring of voltage and frequency for both power sources.
• Automatic Load Transfer: Manages the entire sequence of power sensing, engine starting, and load switching without manual intervention.
• Programmable Time Delays: Features adjustable timers for Engine Start, Transfer to Emergency, Retransfer to Normal, and Engine Cooldown to prevent "nuisance" trips.
• Full Diagnostics: The front-panel interface provides clear status indicators and fault codes for rapid troubleshooting of the power system.
• Source Monitoring: Continuously monitors for over/under voltage and over/under frequency conditions on both sources to protect sensitive downstream equipment.
• PowerCommand Integration: Designed to communicate natively with Cummins PowerCommand generator controllers for optimized system-wide performance.
• Rugged Construction: Built to withstand the harsh electrical environments of industrial and commercial power rooms.

Item Condition (Used - Working)

• Functional Status: Used - Working. This controller was professionally removed from a decommissioned standby power system. It has been bench-tested for power-up and display functionality.
• Physical State: Very good condition. The front membrane buttons are intact and responsive. The LCD screen is clear with no "bleeding" or dead segments.
• Technical Integrity: The terminal connectors on the rear are clean and free of arcing or heat damage. The internal battery (if applicable) is present, though typical maintenance cycles suggest checking its charge before installation.
• Visual Reference: Please examine the high-resolution images to verify the specific MK11 hardware revision and firmware version; the unit pictured is the exact TS1311 controller you will receive.
