Advanced Transfer Switching & Intelligent Power Control Solutions

At CoreUptime Power Systems, we specialize in high-reliability ATS service, controls upgrades, and system modernization for facilities where uptime is mission-critical. With over 40+ combined years of generator, ATS, and controls experience, we deliver solutions that enhance reliability, safety, automation, and compliance across commercial, industrial, healthcare, and data-center environments.

Your Automatic Transfer Switch is the heart of your backup power system — and its controls determine whether your facility experiences a seamless transition… or a costly outage. Our ATS & controls services are designed to eliminate risk, extend equipment life, and raise the performance level of your entire power infrastructure.

Our ATS & Control System Capabilities

ATS Preventive Maintenance & Testing

We perform complete mechanical, electrical, and functional testing on all ATS types, including:

• Open transition

• Closed transition

• Delayed transition

• Bypass/Isolation

• Soft-loading / paralleling strategies

• Mechanically held & electrically held mechanisms

Our annual testing includes:

• Transfer & retransfer timing verification

• Load transfer simulations

• Heater operation and control checks

• Contact inspection and wear analysis

• Mechanical interlock testing

• Control board inspection & diagnostics

• NEC 700/701 and NFPA 110 compliance assurance

​​

ATS Troubleshooting & Repairs

We diagnose and repair complex ATS problems that most general service companies avoid, including:

• Failed control boards

• Sticking solenoids or mechanisms

• Timing failures

• Sensor issues

• Phase rotation faults

• Undervoltage/overvoltage conditions

• Communication failures

• Intermittent or load-dependent failures

When your facility relies on uptime, you need more than “a tech.”
You need a controls expert — and that’s exactly what we provide.

​

Controls Upgrades & Modernization

A controls upgrade is one of the most effective ways to extend the life of older generator and ATS equipment without replacing major components.

We offer turnkey upgrade packages that include:

• Removal of obsolete or unsupported controllers

• Installation of modern ATS control platforms

• Complete wiring conversions

• I/O mapping and programming

• Graphic display installation

• Alarm sequencing and event logging

• Integration with generator controls

• Data/communication integration (Modbus, BACnet, Ethernet/IP)

​​

Common reasons for controls upgrades:

• Controllers are obsolete or unsupported

• Parts availability has become limited

• Intermittent or nuisance failures

• Need for remote monitoring or data tracking

• Upgrading facility loads or code compliance

• Integrating multiple ATS or generators into a unified sequence

​​

Supported brands include:

• ASCO

• Russelectric

• Zenith/GE/ABB

• Eaton/ATC

• Kohler

• Onsite Power

• And more

Our deep experience in UL 1008, UL 891, and paralleling logic ensures every modernization project is completed with precision and reliability.

​

Generator Controls Upgrades

Modern generator controllers offer far superior:

• Reliability

• Alarm logic

• Monitoring capabilities

• Event logging

• Communication options

• Runtimes and efficiency

We install and program advanced controllers from:

• Deep Sea Electronics (DSE)

• ComAp

• Woodward

• OEM-specific upgrade kits

Whether your system requires a drop-in replacement, a full rewire, or a custom-built retrofit, we provide complete engineering, installation, and commissioning.

​

Paralleling & Load-Sharing Solutions

For larger facilities, we offer engineered solutions for:

• Multi-generator synchronization

• Closed-transition switching

• Utility paralleling

• Load sharing & load shedding

• Microgrid and sequence-of-operation design

• Utility coordination

These services position CoreUptime Power Systems to serve industrial, utility, and data-center markets as you expand.

​

Remote Monitoring & Integration

As facilities modernize, remote visibility becomes critical.
We provide solutions for integrating ATS and generator controllers into:

• SCADA

• Building Automation Systems

• Web-based monitoring

• SNMP-based alert systems

• Centralized facilities dashboards

If you want real-time insights into your power systems, we can build the architecture to support it.

​
