Quasi Sine Wave Home UPS/IPS

Combo UPS+

UTL’S COMBO UPS is powered by microcontroller digital technology. It was possible through only this technology that all the appliances including Tube lights, Fans & Computer can run altogether which eliminates the need of two equipments for similar applications, at your home or office. So, it is an Inverter built in a UPS.

  • Micro digital technology
  • Maintains battery health
  • Any battery option
  • Auto overloads resetting
  • Best regulated output-
  • Micro digital technology


Get the freedom to run all your appliances at the same time with the UTL’s Combo UPS. Powered by a microcontroller underneath its hood, it gives you the freedom to use the same UPS in order to run all the different appliances you own. Thus eliminating the need to buy and maintain two back-up systems to run your PC and fans at the same time. UTL’s Combo UPS is the complete solution to all your stored energy needs whether it’s your office or your home, you always get complete peace of mind


The Combo UPS provides the battery installed to it with a constant boost charging current until its voltage reaches 14.2V and the float current then maintains this voltage above 13V. Thus reducing the float current to zero, ultimately resulting in much enhanced battery life keeping it fully charged simultaneously.


The Combo UPS from the house of UTL has the intelligent feature to recognize the type of battery connected to it. May it be an ordinary battery or a branded one, a tubular battery or a sealed one. No matter what the type, it auto adjusts the battery’s charging characteristics accordingly. Even those batteries which cease to go over 13.5V after a while of use work flawlessly with UTL’s Combo UPS. While the UPSs from other brands overcharge such batteries. UTL’s Combo UPS on the other hand declares them fully charged at 13.5 volts, thus preventing them from being overcharged. With an option for battery equalization the Combo UPS from UTL is a complete package. So, go ahead and install any battery you like.


UTL’s Combo UPS has the ability to sense the level of load attached to it. When subjected to excessive load the UPS enters a stand-by mode in which it keeps on beeping and sensing the load and then turns itself back ON when it finds the load to be in its specified level of operation, dismissing the need of manual resetting. If the load is not reduced, the UPS then after 7 attempts to turn itself back ON undergoes shutdown


Get the best regulated output voltage and frequency from no load to full load under all conditions of the battery with UTL’s Combo UPS. A crystal controlled accurate 50Hz supply ensures the hassle free working of your appliances.
