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.
