2 Overview
2.1 Product Introduction
IST7 series product is the high-frequency online double-conversion UPS. It is the high
performance sine-wave UPS that special designed for the network computer room, precision
instrument, etc. of financial, communication, insurance, transportation, tax, army, security,
energy, education, government, enterprise, etc.
2.1.1 Product Features
Three-level inversion technology
Adopts three-level inversion technology, which makes the quality of output voltage wave
better and the efficiency of whole UPS higher.
Completely digitalized DSP control
Adopts digitalized DSP to control the inverting, phase synchronization, output current-sharing,
logic of the power unit, which is with high precision, high speed and perfect whole system
performance.
Energy conservation and high efficiency
Adopts advanced PFC control technology, the input power factor is greater than 0.99, which
greatly improves the use ratio of electric energy and reduces the load of power grid, and save
the cost of power distribution. The size of whole UPS is small, and the weight is light, calorific
value is small, which enhances the use ratio of environment and decrease the investment
cost.
Smart fan speed control
The fan speed is adjusted automatically in accordance with the load status, which prolong fan
life and reduce noise.
ECO energy conservation mode design
The UPS is designed with ECO energy conservation mode. When the user power grid is good,
if the UPS operating in this mode, the bypass prior to output, and the efficiency can be
99%.When the bypass voltage or frequency out of normal range and cannot satisfy the user’s
