The isolation transformer at the output provides galvanic isolation. A UPS without isolation transformer, its output may cause danger to the connected loads in case if there a short circuit occurs in the IGBT blocks of the inverter unit. In that case there is a high probability that the connected loads will be burnt or damaged due to high DC Voltage. Another advantage of the galvanic isolation transformer is that it eliminates the Electrical Pollutions (electrical noise or instant peaks) that might appear at the phase, neutral or earth line. For example, in a rainy day if there hits a lightning at the input, the electrical noise will not be able to pass through the output voltage. As a result the load remains safe. UPS systems along with isolation transformer are more suitable for industrial application.

Eco-mode is a low-cost UPS operational mode, which provides high efficiency (98 %). If the bypass exists in the desired voltage range and the harmonic distortion is not so high, the loads can be fed from bypass instead of from inverter output. As soon as the bypass failure occurs, without any interruption the inverter output starts feeding the load. The user can also manually adjust the UPS to either Normal or Eco - Mode.

display above shows energy flow over its mimic diagram and the position of the circuit breakers. All the parameters of input/output and battery menus are observed on this LCD.

A wide range of common communication options are available with UPS that ensure your command and control over the installed UPS systems wherever they are located worldwide.
