ONLINE UPS

True Double Conversion Design
FRONTLINE Online UPS system, unlike a Line Interactive UPS System, offers the highest level of power protection by regenerating the sinewave and keeps the capacity to correct frequency variation and harmonic distortion. Firstly it converts, incoming supply from A.C to D.C and then inverts D.C to A.C, thereby providing a pure sinewave with tighted voltage and frequency regulation.

Pure Sinewave Output
FRONTLINE state-of-art IGBT(Insulated Gate Bipolar Transistor) inverter, in conjunction with outstanding microcontroller based control circuitry, provides a premium performance and efficiency with a clean and pure sinewave power.

Galvonic Isolation
FRONTLINE Online UPS System isolates its connected load from all types of power problems, which are derived from the main supply.

Wide Input Voltage and Frequency
FRONTLINE Online UPS System is designed to operate efficiently over wide input voltages and frequency without discharging the battery.

Overload and Short Circuit Protection
FRONTLINE's advanced smart circuit system provides that extra protection needed against damage caused by overloads and instant tripping.

Redundancy/Hot Standby Configurations
FRONTLINE UPS Systems offer redundancy, hot standby configuration when configured for a standby.
