Market Memo To: Liebert and Liebert Hiross Partners, Distributors and Sales Associates NEW X-Treme Power Factor Options for Hipulse-E Dear Associate, We are glad to announce the availability of the new X-Treme Power Factor Options for Hipulse-E. The new options are designed to increase significantly the performance of our UPS and aligning it with near-unity or sometimes leading power factor loads in new Data Centers and IT and Networking applications.

X-Treme Power Factor for Hipulse E

The new Options allow the Output Performance to stretch all the way to support 0.9 Leading Power Factor loads, with no derating with respect to the rated UPS Output. This means that the UPS will be capable of functioning at 100% of its rated output, thus providing 100% of Active Power or kW in all conditions between 0.8 lagging and 0.9 leading. A press release has been anticipated to the press through our Press Agency and its contacts across Europe in occasion of the Italian Electrical Trade Show INTEL 05. English and Italian text are attached with this memo.

1. Background Traditional Switch Mode Power Supplies used in computers were designed in the past with a rather low, and generally lagging active power factor. Common values of 0.7-0.8 were typical in data centers. New power converters used in modern servers and other IT equipment, are now presenting a much higher power factor, close to unity in many cases, and with a slightly capacitive or leading characteristic. Traditional transformer-based UPS technology now faces a new challenge to cope with these loads. With the new Hipulse E, thanks to a clever combination of the output transformer and the capacitive filtering technology, we are now able to fine tune the UPS output performance to support the new application requirements. 1. Main Features With your Hipulse E orders there are two new options:

• Power Factor Tuning “1” or Unity • Power Factor Tuning “0.9 Leading”

These options allow the UPS Output Inverter to operate without derating under the following conditions: Power Factor Tuning “1” or Unity = No derating of the Active Power (kW) of the Inverter with loads up to 0.95 Leading. No variation of the other performance conditions of the UPS for Lagging loads. This option is ideal for loads working typically between 0.8 lagging and unity – a typical data center, with a combination of new and old servers, and other non IT loads connected to the UPS, such as motors, or Air Conditioning equipment.

Power Factor Tuning “0.9 Leading” = No derating of the Active Power (kW) of the Inverter with loads up to 0.9 Leading and 0.9 Lagging. When using this option there is a small derating factor for loads between 0.8 and 0.9 lagging (up to 8% derating at 0.8 lagging) This option is ideal for loads working typically around unity or between unity and 0.9 leading power factors. New data centers, with a predominance of new server and IT / Networking equipment and no inductive circuits – such as motors, transformers, etc.

NOTE: When ordering Hipulse E units without the X-Treme Power Factor options it must be noted that a derating factor must be applied when supplying power to leading loads. In this situation the unit will supply approximately 76% of its rated output power (i.e. at 300kVA, rated output 240kW, with 0.9 leading PF = 183kW). 2. Part Numbers and Availability We are introducing two new digit values in position 23 of the Hipulse E configuration string (as shown at the end of this document). Retrofit installation in older Hipulse or Hipulse E units is possible, but will require previous Engineering and Service onsite evaluation and approval. Also future modification of units will be possible (for example from a “unity” rated option to a “0.9 leading” version) with prior agreement with our Engineering and Service teams. 3. Availability and Lead Times We foresee no significant change in UPS lead times for these otions, however, please consider an additional 2-3 weeks compared to standard lead times at least for the first few months of introduction, while changes on all units and ratings are being rolled out in the factory.

4. Pricing Pricing for these new options is summarized in the following table. NOTES: - There is no difference in pricing between the “unity, PF 1” version and the “0.9 Leading PF” version. - Base Model pricing for Single Module systems is included in the table only for your reference.

Documentation Press releases in English and Italian for the new options are attached. A PowerPoint presentation with graphs used also in this memo is also included with this memo (to allow you to prepare custom material for your communications). Our press agency Pragmatika will also have available a “by-lined” article on leading power factor loads and new trends in Data Center loads for your press contacts. The article supplies some more background information explaining the new trends and its meaning for UPS and Generators. We are also planning a Webcast, which will be announced next week, to present these new options and discuss its features and benefits. For more information and feedback do not hesitate to contact us at the addresses below or through the [email protected] email address.
