The Eaton® 9355 uninterruptible power supply (UPS) is a true online, double-conversion, three-phase system that can be used to prevent loss of valuable electronic information and minimize equipment downtime. It is ideal for protecting essential information technology and electrical engineering infrastructure in corporate, telecom, health care, banking, and industrial applications.
The Eaton 9355 UPS continually monitors incoming electrical power and removes the surges, spikes, sags, and other irregularities that are inherent in commercial utility power. Working with a building's electrical system, the UPS supplies clean, consistent power that sensitive electronic equipment requires for reliable operation. During brownouts, blackouts, and other power interruptions, batteries provide emergency power to safeguard operation.
With the Eaton 9355 UPS, you can safely eliminate the effects of electrical line disturbances and guard the integrity of your systems and equipment. Figure 1 shows the Eaton 9355 UPS (20/30 kVA) with an optional Extended Battery Cabinet (EBC) and Options Cabinet.Hot Sync Paralleling Technology allows for paralleling of as many as four 9355 UPS units



The system is capable to provide backup power for dual or single phase equipment through automatic power regulation.


Two battery strings are included.  (Battery string cost is $1,401)


Battery strings capacity per ups - 6 battery strings .


You can purchase additional battery strings for extending the runtime.

You also can add a battery cabinet from our shop.

What could happen if  The Uninteruptible Power Sypply is not properly sized?


1. In case of the UPS is not properly sized, you might need to return the UPS if the vendor accepts it and pay for restocking and transportation. You may also lose time and miss project deadlines, or the UPS and your equipment might fail or get damaged due to overheating.


2. In case the power outlet or power source is not properly sized, you might need to use improvidsed connections that might void the equipment waranty and might lead to improper functionality of the UPS or your equipment.


 3. When power grid fails or have high voltage spikes, you may experience :

- productivity loss due to the UPS lack of capacity to handle such scenarios

- equipment damage due to overload

- data loss if you have servers due to UPS sudden failure

- fire hazard due to overheating


In any 3D Printhouse, Engineering and Development envirnment, Manufacturing facility, Medical office, Data Center or Server room you have electric equipment worth hundreds of thousands to millions of dollars, which can be damaged during power outages due to fluctuant surcharge of the power grid.


When power grid fails, keep your systems working with ROINRO's UPS - Continuous Power.

  • Continuous power systems are used everywhere, from homes, hospitals, medical offices, engineering companies, web companies, data hosting companies to army and governmental agencies that need continuous power during power outages.

    Continuous power can be provided with Uninterruptible Power Systems (UPS) alone or combined with stand-by generators.


    Continuous Power Systems main benefits: 

    - connect directly to grid and to the device that is protected. 

    - eliminate potential device damages caused by power grid fluctuations

    - sustain device functionality when power grid fails

    - reduce liabilities due to device unexpected failure

    - sustains Business Continuity when a power outage occurs for the duration of the UPS run-time

    - it is plug and play

    - it is more effective versus stand-by generators as it provides no interruption and continuoslyprotects the equipment

    - sustains longer run-time when using extended runtime battery pack.

    - easy system configuration 

    and many more features.
