2 Introduction to Eaton UPS The Eaton® 93PM uninterruptible power supply (UPS) is a true online, continuous-duty, transformerless, double-conversion, solid-state, three-phase system, supplying conditioned and uninterruptible AC power to critical load and protecting it from power failures. The UPS is used to prevent loss of valuable electronic information, minimize equipment downtime, and minimize the adverse effect on production equipment due to unexpected power problems.
2.1 Looking inside the UPS system The Eaton 93PM UPS is a continuous-duty, solid-state, transformerless, three-phase, true online system that provides conditioned and uninterruptible AC power to the UPS system’s output and critical load. The basic system consists of a rectifier, battery converter, inverter, static bypass switch, monitoring/operation control panel, integrated communication server, and digital signal processor (DSP) logic.
2.2 UPS operating modes UPS operating modes: • Normal operating modes: • In double conversion mode, the critical load is supplied by the inverter, which derives its power from rectified utility AC power. In this mode, the battery charger also provides charging current for the battery, if needed.
Internal relay contacts Figure 2-3: Path of current through the UPS in double conversion mode During normal UPS operation, power for the system is derived from a utility input source. The front panel displays Normal, indicating the incoming power is within voltage and frequency acceptance windows.
2.2.1.2 Energy Saver System mode In ESS mode the UPS safely provides mains current directly to the load when the input is within the acceptable limits by its voltage and frequency. Surge protection and some filtering is also provided, ensuring that clean power is delivered to the load equipment. Should there be any disturbances detected in the incoming power, the UPS switches to double conversion and continues to supply the critical load through its inverter.
2.2.2 Stored energy and battery mode When running normally in double conversion or ESS mode, the UPS automatically transfers to supply the load from batteries or other stored energy source if a utility power outage occurs, or if the utility power does not conform to specified parameters.
2.2.3 Bypass mode The UPS automatically switches to bypass mode if it detects an overload, load fault, or internal failure. The bypass source supplies the commercial AC power to the load directly. The UPS can also be commanded to transfer to bypass manually through the display. Figure 2-6 below shows the path of electrical power through the UPS system when operating in Bypass mode.
2.3 UPS features The Eaton UPS has many features that provide cost-effective and consistently reliable power protection. The feature descriptions provide a brief overview of the UPS standard features. 2.3.1 Advanced Battery Management Advanced Battery Management technology uses sophisticated sensing circuitry and a three-stage charging technique that extends the useful service life of UPS batteries while optimizing the battery recharge time.
2.6 Battery system The Eaton 93PM 30-50kW UPS can be equipped with internal batteries to provide a 10-20 min runtime depending on UPS rating and load level. In addition, external battery cabinets can be introduced to the system to allow extended autonomy. Internal and external batteries can be used in parallel.
6. Have authorized service personnel perform preliminary operational checks and startup. NOTE Startup and operational checks must be performed by an authorized Eaton Customer Service Engineer, or the warranty terms specified in Warranty become void. This service is offered as part of the sales contract for the UPS.
The UPS system installation must meet the following guidelines: • The system must be installed on a level floor suitable for computer or electronic equipment. The floor must be suitable for heavy weight and wheeling. • The system must be installed in a temperature and humidity controlled indoor area free of conductive contaminants.
