Combo UPS

Micro Digital Technology:
UTL COMBO UPS is powered by micro controller 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.

Battery Health for longer life :
Battery is fed a constant boost charging current until the voltage of each Battery reaches 14.2 V and then float current (very close to zero) maintains it above 12.9 V. Thus float current ( flowing for the longest period in all this process) is reduced to nearly zero, ultimately resulting in much enhanced battery life, while keeping it fully charged simultaneously.

Any Battery Option :
After a period of time some Batteries do not go beyond 13.5 V while charging. Normally, in this case Battery are over charged by normal Inverters. UTL COMBO UPS declares the Battery is charged, in this conditions, and maintains it on float voltage level. This way, user has option of installing any Battery with UTL COMBO UPS. It also provides the option of battery equalising.

Auto Overload Re-setting :
UTL COMBO UPS shuts down automatically if exposed to excessive load and keeps on beeping & sensing the load to switch itself on to find the load within the specified limits, eliminating the need of manual resetting by the user. If the load is not reduced UTL COMBO UPS will shutdown after 15 such attempts and user will need to restart it manually.

Best regulated output :
UTL COMBO UPS has regulated output voltage & frequency from no load to full load under all conditions of battery. Frequency is crystal controlled accurate 50 Hz under all conditions.
