BEHIND THE SCENES
Powering On: A Look at NXT
Power’s UPS Systems
We sat down with NXT Power’s Director of Engineering to get an inside look at how they develop theirUPS systems and why they stand out from the crowd.

As a young boy, Cherian Jose was always “curious about how stuff works”. With his older brother at his side, Jose could—for hours—be found tinkering with small
appliances and the like, learning how things worked by
taking them apart and re-assembling them. “What
began as fun playtime with my brother Martin
opened up for me a challenging lifelong career
of understanding and harnessing power.”
In his teens, Jose became passionate
about cars, modifying them to maximize
power and efficiency. There was a period,
In his role as Director of Engineering
at NXT Power, Jose applies his talent for
new product innovation and understand-
ing the mechanics to ‘make it happen’ in
designing each power conditioner and UPS
system produced by the company.
“At NXT Power, we believe that you have to

control both normal and common-mode voltage to
achieve good electronic performance.”
We recently sat down with Cherian Jose to learn more about
the work he is leading at NXT Power and discover how he applies
innovation in his role at this forward-thinking company.
Cherian Jose (CJ): We collaborate as a Team to determine what needs exist in the marketplace and how to best design a product to fill in the gaps. The Integrity Pro series, forexample, is a culmination of almost 30 years of my power conditioner and battery backupexperience coupled with market conditions. By that I mean, for instance, the new MedicalSafety Standards 60601-1 that requires only equipment with very low leakage current (<300microamps) to be placed near a patient.
The Integrity Pro Medical UPS meets these standards while using a low impedance isolation transformer that delivers uninterrupted, clean power with virtually zero volts betweenneutral and ground. This product is also ideal for medical device manufacturers as theUL-certified Integrity Pro helps them meet compliance requirements.
NED: What was the problem to be solved in the development of the Integrity
CJ: So much of the way the world works today is microprocessor-based which meansthere’s lots of equipment that needs to have quality power. With the Integrity Pro UPSline, they also receive backup power protection in the event of power loss. This backupprotection provides extra time to save work or ride through a momentary power outage.
NED: What was the biggest challenge your team faced in designing the
Integrity Pro models?
CJ: One of the biggest challenges the Design Team had to overcome was the developmentof an easy-to-understand LCD display. We sought to create a display that shows actual dataas we believed current LED displays did not provide reliable real-time information. Thisdesign innovation allows the customer to capture real power quality information in termsof numbers and words.
Also, the Pro Medical model is designed from the ground up to incorporate itself flawlessly and safely into various patient environments. Each unit meets the safety requirementsof IEC60601.1 and UL60601-1 (300 microamps of leakage current) to ensure both patientand medical staff are safe.
With regards to the Pro Retail UPS, the sleek design is for advanced POS [Point of Sale]terminals as it can easily incorporate itself into environments such as restaurants andC-stores. The Pro Retail also provides a 24V DC connection and eliminates the need fora power brick, also known as a “wall wart.” Every unit meets the safety requirements ofUL1778 to ensure product safety and reliability while providing best-in-class power quality.
NED: How did you come up with the idea for the NX T Power product line?
CJ: As a team, we discussed the market needs and conducted a gap assessment, consideringwhat options may work and how best to approach the design with the customer in mind.
For example, another of our products is the Integrity Max. We foresaw that any powerdisturbance during the 3D production cycle diminishes yield and causes the process tostop, delaying completion and missing deadlines. With the Max UPS system, manufacturers and designers of 3D products now have quality power protection plus a low impedanceisolation transformer that delivers that all-important uninterrupted, clean power.
NED: What makes Pro Retail remarkable?
CJ: I have found that trustworthy power is a vital element for advance POS systems. POSequipment has very minimal power requirements these days. As a result, NXT Power has a
250 and 400VA UPS to meet this need.
It also provides a 24V DC connection and eliminates the need for a power brick.
