CE+T is a solutions provider for the telecommunication, industrial, and data center markets in support of their critical power requirements. Founded in 1936, CE+T is an industry leader in power conversion technology. The announcement of the TSI has revolutionized the inverter market with its new range of modular scalable products to support telecom (24VDC, 48VDC) and industrial (110VDC, 220VDC) applications.

Building your system portfolio to meet your varied power demands requires you to have an easily configurable product architecture. TSI technology makes it simple to size and select your inverter configuration without compromising the performance of your system or your budget.

The TSI inverter is modular and scalable to capacities up to 75KVA 3 phase, 80KVA dual phase and is easily configured to your current and future AC requirements. TSI inverters are available in either 1500VA (Media) or 2500VA (Bravo) building blocks.

The TSI Distributed Static Transfer Switch Technology eliminates the single point of failure in a traditional inverter design. Unlike hard transfers between energy input sources the TSI “soft switching” method is disturbance free.

The TSI inverter is field upgradeable and its hot swappable modular design reduces risks caused by exposing your critical load to an unpredictable AC source. There is no need to go to bypass when adding or changing the capacity of your inverter system.
