Eaton 9395XMegawatt UPS with silicon carbide
Eaton's new UPS for data centres and critical infrastructure delivers 900–1,700 kW in a single system. Silicon carbide (SiC) power electronics give up to 97.5 % efficiency in double conversion, and according to Eaton the system takes up to 30 % less floor space.
The technology
More power on less floor
The 9395X is Eaton's first large UPS with silicon carbide power semiconductors. SiC components switch faster and with lower losses than traditional silicon IGBTs. The difference can be measured directly in a data centre: less space for the UPS, less heat to remove and more power per square metre.
Air is drawn in at the front and exhausted at the top. No clearance is therefore needed behind the system, and it can stand against a wall or back to back with another system.
Up to 30 % less floor space
Every square metre in a data centre is planned for IT. A smaller UPS room frees up space for racks.
Up to 50 % higher power density
1,700 kW stands on 3.22 × 0.92 m. That is approx. 574 kW per square metre of footprint.
Up to 30 % lower heat loss
Lower heat loss means less cooling to size, pay for and maintain.
The percentages are Eaton's own and compare with earlier generations of the 9395.
Energy use
Highest efficiency at part load
A UPS in a data centre rarely runs at full load. With 2N redundancy each system is loaded to 50 % at most, and with N+1 the load is also below full load. It is precisely between 25 and 50 % load that the 9395X reaches its highest double-conversion efficiency: 97.5 %.
ESS mode
In ESS mode (Energy Saver System) the load is supplied via bypass while the system monitors the mains. On a mains fault it switches to double conversion in under 2 ms, so the IT equipment does not notice the transfer. Efficiency is 99.0–99.1 % at 25–100 % load.
| Model | 25 % load | 50 % load | 75 % load | 100 % load | Heat loss at 100 % |
|---|---|---|---|---|---|
| 900 kW | 97,5 % | 97,5 % | 97,1 % | 96,5 % | 32.6 kW |
| 1,020 kW | 97,4 % | 97,5 % | 97,0 % | 96,1 % | 41.4 kW |
| 1,125 kW | 97,5 % | 97,5 % | 96,9 % | 96,1 % | 45.7 kW |
| 1,500 kW | 97,5 % | 97,5 % | 97,1 % | 96,5 % | 54.4 kW |
| 1,700 kW | 97,4 % | 97,5 % | 97,0 % | 96,1 % | 69.0 kW |
Design
Power modules that configure themselves
The system is built from 300, 340 or 375 kW power modules (UPMs) in a common frame with I/O section and static bypass. The modules are plug-in and configure themselves when inserted. Up to four systems can be paralleled with Eaton's HotSync.
How we size
We always size with 25 % room for expansion. In the 9395X that means a frame with free module slots, not modules running unloaded from day one. Cables, fuses and switchboards are sized for the frame's full rating, so expansion does not require rebuilding the installation.
1–5 modules per system
Power follows the number of modules, up to the frame size.
Up to four systems in parallel
HotSync shares the load between systems without a communication link for synchronisation and load sharing.
Service without dropping the load
A module can be removed for service while the other modules supply the load.
Models
Seven power ratings from 900 to 1,700 kW
The model designation states the system's rating. Dimensions apply to single feed (small I/O section). With separate bypass feed (large I/O section) the system is 400 mm wider and 140 kg heavier. The price depends on configuration, batteries and installation, so we quote after sizing.

Batteries
VRLA today, lithium-ion when you are ready
The 9395X works with a DC voltage window of up to 700 V and can be supplied from VRLA, lithium-ion and NiCd batteries. The batteries are charged with Eaton's ABM technology, which charges in periods and rests in between instead of holding the batteries at constant voltage. This is gentler on the batteries.
Our standard fits directly
We build battery systems with CSB blocks to Eurobat 10+ years, 40 blocks per string and at least two strings on Kunstmann racks. 40 blocks are within the voltage window of the 1,020 and 1,700 kW models, and we set the end-of-discharge voltage to 1.75 V per cell ourselves, within Eaton's range of 1.67–1.75 V.
| Model | Blocks | Cells | DC voltage |
|---|---|---|---|
| 900 and 1,500 kW | 36–50 | 216–300 | 360–700 V |
| 1,020 and 1,700 kW | 40–50 | 240–300 | 400–700 V |
| 1,125 kW | 44–50 | 258–300 | 440–700 V |
| Space | 50–80 % less |
|---|---|
| Weight | 60–70 % lower |
| Recharging | 2–3 times faster |
| Service life | Up to 2 times longer |
Operation and security
Built for operations that must not stop
A system of this size often protects an entire data centre. That is why much of the 9395X is about detecting faults early, keeping the load supplied during service and being able to document that the system works.
HotSync without a single point of failure
Parallel systems share the load without a communication link for synchronisation and load sharing.
Fault discrimination
The system distinguishes between faults upstream and downstream of the UPS and reacts so that the critical load is protected.
Easy Capacity Test
The UPS can be tested at full load without an external load bank, because the energy is circulated internally. During commissioning we still test batteries, generator, cables and cooling with a load bank.
Cybersecurity
The network cards are certified to IEC 62443-4-2 and UL 2900-1. Eaton Cyber Secured Monitoring provides monitoring and health reports via a secured cloud.
EnergyAware
With lithium-ion batteries, part of the battery capacity can be made available to the grid. Eaton states typically up to €50,000 a year per MW allocated to grid support.
