Ensure your UPS is ready for action

with factory test reports, startup testing & more from certified technicians


Unlike other UPS suppliers, every UPS from Mitsubishi Electric is tested prior to shipment and is furnished with the signed factory test report. An optional Factory Witness Test can also be performed at the Warrendale, PA facility with the end customer present. Proper UPS testing is essential to establishing baseline metrics and ensuring the highest level of performance.



Critical UPS Testing Phases




Phase 1 | Factory Testing

Factory testing is performed before a UPS leaves our Operations Center in Warrendale, PA. Equipped with two test labs with 3MW resistive and 375kVA reactive load banks available, the standard test uses factory-provided batteries and simulates real-world scenarios to determine performance and efficiency under varying conditions.


Customers are then provided with a factory test report to guarantee seamless installation and commissioning. Standard testing includes:

  • Measurement of steady state characteristics (efficiency & input voltage performance)
  • Measurement of transient response
  • Output transfer test
  • UPS overload test
  • AC input failure recovery

Customers can also request additional tests and are invited to view real-time data and results at our Operations Center. 

Mitsubishi Electric provides factory testing and reports before our systems get to your floor.

Trust Mitsubishi Electric technicians to handle UPS installation and startup.

Phase 2 | UPS Installation & Startup Testing


After UPS installation, a factory-authorized technician should perform startup testing to confirm the system has been installed properly. This is the best way to enact proper procedures and ensure adherence to warranty protocols. It's also an additional benchmark for performance data and an opportunity for onsite training.


UPS installation and startup testing centers around powering up the UPS and running it through a series of checks and balances. These often include infrared scanning of electrical equipment and initial onsite tests.


Phase 3 | Onsite Testing


Onsite UPS testing helps identify any areas requiring maintenance or other updates and can be done at any point once the system is up and running. It can include any number of performance tests, but generally involves the following:


  • UPS battery testing: Battery run-down evaluations to check connections and cells, and capacity testing to ensure the size of the battery matches the output needed for the system.
  • Load-bank testing: Verify that load carrying characteristics meet specifications
  • Harmonics testing: Ensures distortion is not being fed back to the utility, which could affect nearby equipment.
Leverage UPS testing to ensure your system is running smoothly.

Phase 4 | Commissioning Testing


Commissioning testing should be done before integrating your UPS system with the rest of your equipment. It includes load-bank testing and lets you know how your system will perform under an actual load in varying conditions.


UPS battery rundown testing, burn-in tests, and capacity tests are also completed during commissioning. The data collected in this phase creates a solid baseline of operation with which to compare future performance tests.


Phase 5 | Integrated Systems Testing


This measures not only the performance of your UPS system, but also how it affects and integrates with the other equipment in your facility, including:

  • Generator, grounding system and breakers
  • Automatic transfer switches (ATS)
  • Power-distribution units (PDU)
  • Cooling systems 
Mitsubishi Electric provides load bank testing, UPS battery testing and infrared scanning of electrical equipment.

Establish a Maintenance Routine after UPS Testing


Monitoring equipment performance doesn’t stop after initial test phases are complete. Routine maintenance and testing allows for documentation of performance over time, which can help identify issues or predict when repairs may be needed. It can include infrared scanning of electrical equipment, UPS battery testing, parts cleaning and replacement, documentation of systems changes and issues for warranty claims, and more. A trained Mitsubishi Electric technician can administer these tests for you and provide recommendations for getting the most out of your UPS. We recommend preventive maintenance visits twice a year.
