What makes Eaton UPS better than the Others

With over 50 years of experience Eaton have developed the most resilient and economical UPS systems  in the world.

Resilient Design

Hot Sync:

Eaton’s ‘Hot Synchronization’ technology allows multiple parallel inverters to synchronies and share current without reliance on control  cabling between them. The advantage of this is it makes the UPS more reliable due to the parallel inverters not being susceptible to a common point of failure. This being the parallel PCB’s and communication cables in other designs.

Back feed protection contactor:

Eaton has static switch back feed contactor option as standard in its UPS systems. This adds significant advantages to the system reliability when operating within a parallel application and makes  the UPS fully compliant with AS62040-1.

Advanced Battery Management (ABM) and Battery Testing:

Batteries are the most critical component of any UPS. The battery is all too often ignored as a maintenance-free product, not requiring attention or inspection. This neglect, though common, can be costly and possibly disastrous. ABM, by its nature, helps to provide early detection of problem batteries and thus protect the battery from unnecessary failures, while functioning to extend the useful life of this key component of power quality.

Eaton’s ABM technology solves the three fundamental challenges inherent to all batteries. It uses a unique three-stage charging technique that significantly extends battery service life and optimizes recharge time, compared to traditional trickle charging.

Fan redundancy and Fan monitoring:

As standard Eaton fits individual fan monitoring within its UPS units, this alerts the customer in the event of a fan not working so it can be replaced. Additional to this, Eaton’s UPS units are designed with fan redundancy,  if a single fan where to fail the unit will still be able to operating at 40 degree ambient while supporting 100% of the load continuously.


Continuous operation at 40 degrees:

All Eaton 9 Series UPS units are designed for continuous operation at an ambient temperature of up to 40°C, without de-rating. It is also capable of delivering safe power in even of higher temperatures, without shutting down. This allows high availability even in conditions other than standard room temperature.

Class Leading Efficiency – Double Conversation Mode:

Eaton’s Premier series UPS units , 93PM ,93PS , 93PR & 9395P are achieving up to 97% efficiency in double conversation with above 96% efficiency for load profiles 25 - 100% *.

Variable Module Management System (VMMS):
 

Eaton’s Variable Module Management System (VMMS) is aimed at increasing efficiency without compromising reliability. In modular UPS system that are loaded below 20% VMMS can be activated to placed modules into suspended mode  giving the UPS the efficiency of a system loaded at 50% while having the capacity of the suspended modules instantly available when needed. This results in a UPS system with a higher efficiency curve at lower load levels.

Energy Saver System (VFD):
 

Eaton have patented software control which allows for the following insurances when the unit is operating in VFD.

The 9395 is able to achieve a transfer time from ESS mode to Inverter of 2 milliseconds in all types of mains failure conditions where as other designs can take up to 8 milliseconds to transfer depending on the type of failure.   Eaton is able to achieve this because it has developed proprietary techniques to commutate the static switch under various conditions. Using these techniques, Energy Saver System can turn off the static switch in 600 microseconds rather than waiting potentially eight milliseconds for the next zero crossing to switch off the static switch.

Eaton’s propriety technology is also designed to detect if a mains failure is occurring due to a upstream or downstream short circuit (ground fault) when the UPS is operating in ESS mode. While in ESS mode, this is significant because if a downstream short circuit is detected the 9395 will remain on static bypass to allow enough current for the downstream protection to clear the fault, other UPS manufactures VDF operation will see the downstream short circuit as a mains failure and transfer the fault onto the inverter limiting the current. In the event of a upstream short circuit occurring the 9395 will transfer to inverter immediately removing the critical load from the fault.

Easy Capacity Test:

The Easy Capacity Test feature re-circulates energy from the UPS for testing. So there’s no need to spend money renting load banks, and no time or energy wasted on temporary load connections.
ECT makes on-site testing easier during commissioning and scheduled maintenance by eliminating the need for big and expensive load banks and testing related operational costs.
