An obvious choice for IT applications, the heavy duty design of the HF Series also works equally well with other loads such as motor driven loads, medical equipment, communication products which are often damaged by inferior UPSs with step wave or square wave output.
As a rugged series designed for Indian power conditions, the HF Series UPSs scores over most other systems in the market, affording high compatibility with most types of generators.
In rare instances where the primary UPS system goes out of order the standby UPS instantly takes on the connected load without transferring to bypass. This configuration is available on selected models at an additional cost.
