% Load The efficiency of Galaxy VM is higher than Delphys Green Power at every load, the difference begin more obvious at higher level loads. The Galaxy VM efficiency curve is nearly flat down to 25% load, saving power and cooling costs and significantly reducing the overall total cost of ownership.

Electricity savings Rule of thumb: +1% efficiency improvement @ 100kW = -800 € savings per year (1)

kWh price = 0.08€

In the tables, different energy saving cases are presented after 1 year, 5 years and 10 years. Saving energy is of great importance, because every percentage of efficiency directly affects total cost of ownership (T CO) of the UPS system over time. Table: UPS in double conversion mode Formula: Annual energy saving = Pu x (1/ c - 1/ s) x H x C Pu = kW at UPS output c = Delphys Green Power efficiency s = Galaxy VM efficiency H = number of hours in 1 year (8760 hours) C = kWh price = 0.08 €

2. High impact on OPEX thanks to the econversion™ mode With econversion™ mode, Schneider gives to the customer the best efficiency. The system consists to switch on bypass mode the UPS. Efficiency increases up to 98.5%. System works with 100% non-linear load and the transfer time is 0 ms. Thanks to a fast transfer, classification of this function is class 1 (the best):

?

econversion™ mode also has an impact on the all electrical equipments (cable, transformer, genset, switchgear, circuit-breaker) …installed upstream of the UPS. During this mode, the UPS inverter compensates the main disturbances such as the load THDi and the load PF. Delphys Green Power doesn’t have this function.

3. Fully compatible with diesel generator Galaxy VM is fully compatible with a generator: ● Large input voltage window ● Large input frequency window ● Low input THDI at varying load rates ● High input PF.

42 to 65 Hz 3.0% 0.99

 Also with a large input voltage window and a large input frequency window, the battery is less solicited. Life expectancy of the battery is not reduced.

4. Swappable battery modules and fans for highest system availability To minimize MTTR, some components in the Galaxy VM are swappable by the user, and operation procedures have been simplified. Some procedures have been reduced to 10 minutes MTTR (by an operator). For the same action, the Delphys Green Power procedure requires 1 hour MTTR or more (by a service technician) to replace the batteries.

Battery modules Fans Other

Swappable components Galaxy VM Delphys Green Power Yes No Yes No No No

Galaxy VM is designed to replace each component separately. The weight of each component is very low. During maintenance on one component (one fan or one battery module), the load remains protected during a replacement.

Modular battery cartridge

@

Narrow and wide modular battery cabinets

For Delphys Green Power, batteries and fans are not swappable or fast replaceable. MTTR to replace the traditional batteries or fans is very long. During a battery or fan replacement, Socomec transfers the load on maintenance bypass. Load is supplied but not protected.

5. Advanced battery management included on modular battery offer Galaxy VM includes a battery management as standard offer (only for modular batteries). With advanced monitoring capabilities, the Galaxy VM UPS detects failing battery string before they can become a problem: ● Each individual string monitors and reports its current and voltage. ● Quickly identify and replace faulty battery units. ● Faulty string is identified with an alarm on display and Led in the modular battery cabinet. Delphys Green Power doesn’t include a battery management as standard offer. However they have an optional battery management: BHC Interactive offer.

6. Better maintenance advice to guarantee installation availability The "Life Cycle Monitoring" (LCM) f unction provides UPS maintenance advice to guarantee installation availability for the user. The display gives 3 messages enabling the following to be identified:  The end of the contractual legal warranty: "End of warranty check recommended".  Regular maintenance requirements and the end of service life for consumable components: "Technical check recommended".  The end of the battery service life: "Battery check required".

Benefits: Better installation availability. Better maintenance planning. Delphys Green Power doesn’t have this system.

7. Galaxy VM more robust and meets typical industry standard Benefit The advantage of the ov erload capability is to supply a higher power (in-rush currents) during transient period. And that without transfer the load on AC bypass source (reserve source). Case in point The load in-rush currents come from:  Transformer magnetizing,  Starting of variable-speed drive,  When additional servers are added in a datacenter,  Loss of one UPS in the case of parallel configuration,  Loads supplied with STS, STS transfers the load from Priority source (UPS1) to Secondary source (UPS2).

The overload capability of the Delphys Green Power doesn’t allow meeting this need. During this transient period the load will be transferred on AC bypass source. The load will be not protected by the UPS.

8. Conform in terms of safety In order to avoid electric shock hazard, that may be caused by backfeed of energy vi a the electronic static switch (on AC Bypass source) or v ia the input rectifier (on AC Normal source), an external or internal disconnector must be installed in conformity with the Product Standard IEC62040-1 paragraph 5.1.4. Galaxy VM integrates in standard the backfeed protection. This complete offer integrates 2 contactors: 1 contactor on AC Normal source and 1 contactor on AC Bypass source. The backfeed contactors are installed inside UPS. For Delphys Green Power, the backfeed protection is an option. To get the same safety level, Socomec must propose this option  the UPS price will increase. The backfeed protection proposed by Socomec is a light offer. The backfeed contactor is controlled by a communication card. The contactor is external and it m ust be installed by the customer inside the Distribution Panel. Extract of the Socomec’s User Manual:

External backfeed contactor on AC Bypass source

No backfeed contactor on AC Normal source

Distribution Panel of the customer

Communication card to control the backfeed contactor

The price of the contactor and its i nstallation is supported by the customer. For Galaxy VM, there are:  No additional price for the customer. All components (backfeed contactors and their controlled card) are included i n the standard offer/price.  No additional time to install the back feed contactors. B

9. Graphic touch screen display Galaxy VM is equipped with a 7” touch screen color display. The Delphys Green Power UPS is designed with a standard graphic display. The Galaxy VM touch screen interface benefits: - Operator Instructions: provides detailed essential UPS operating procedures, - Animated Mimic Diagrams: - System-Level and Module Level, - Indicates major component status, power flow, and breaker position, - Alarm/event log: time/date stamp for all al arms, - Detailed component status: indicates operating status and v alues for input, battery, rectifier, inverter, and output,

10. Schneider employs redundant displays The mimic diagram of the Delphys Green Power is included on the graphic display. Potential failure scenario:  If the display ceases to operate, the customer or field engineer doesn’t have any more access to the status of the UPS. With Galaxy VM, the customer or field engineer always has access to the status of the UPS.

11. ON/OFF buttons to start and stop the UPS without display instructions No ON/OFF buttons (the function is controlled by using the keypad on display) could result in loss of load – a number of loss of load incidences occur as a result of human error and lack of training. The lack of a physical ON/OFF (Socomec provides virtual buttons on a front mounted screen) this could contribute to a critical loss under certain conditions. C

Potential failure scenario:  If the UPS unit is in RUN mode and the display c eases to operate (vibration, electrostatic discharge), how can you transfer the UPS to bypass for maintenance? Firstly, the UPS will be stopped by the opening of the output switch, secondly the opening of the rectifier switch in the second time  Load loss!
