TSi Power Corporation was founded in 1998 to provide industry-leading power solutions for communications, security, factory automation, hospitals, laboratories, defense and OEM customers. We’re the Ultimate Power Solution.

Power products built to succeed.

We make high-quality UPS, inverters, automatic voltage regulators, isolation line conditioners and automatic transfer switches for both indoor and outdoor applications. TSi Power offers a full line of standard products, along with configurable and custom solutions. Our specialty is low- to medium-volume power solutions for a variety of situations, including unusual and challenging applications. We typically make products in the US but can offer higher volumes at lower prices through TSi Elecpower, our Indian sister company.

We design products that will continually operate 24/7 at the limits of stated specifications. We don’t accept short cuts in materials and engineering – not from ourselves, nor from our suppliers. Our customers can trust that our products are conservatively designed and built from properly sized components. This is especially important for DC-AC power inverters and UPS with extended back-up time. Power conversion and protection products are like a house foundation and if not properly designed, they will fail when pushed too hard.

At TSi Power, our products are built to succeed, time after time.

Our commitment to you.

Our commitment to our customers is simple: a technically competent sales engineer will serve you directly from concept to production and beyond. What does this mean?

  • Faster communication, because information does not have to travel back and forth through multiple layers of people
  • Reduced time to market
  • Unnecessary markups are eliminated
  • Personalized service and follow-up
  • Responsive technical support

Our sales process.

TSi Power exports products all over the world. We have provided power solutions to customers in Africa, the Middle East, Mexico, South America, Singapore, Australia, Canada, Europe, Japan, Iraq, Afghanistan, India and Pakistan, to name a few. By doing business throughout the world, we solidly understand the issues surrounding quality of power generation, transmission and distribution infrastructure – along with the operating environmental conditions that affects the quality of power – in different countries.

At TSi Power, we prefer to sell our products directly to end users, systems integrators and value added resellers. This not only eliminates middlemen and unnecessary mark ups, but it also improves communication with the actual customer – ensuring our customers get the right solution for their needs.

When you work with us, a TSi Power-trained sales engineer handles all customer inquiries and will organize resources needed to provide a quotation or resolve a problem. Our sales engineers work with each customer from initial inquiry to production to make sure the project stays on schedule, reducing the overall time to market. TSi Power also provides support for system start up and maintenance to assure reliable product performance.
