Any Double Wound Transformer is inherently an ISOLATION TRANSFORMER as the primary and secondary are isolated from one another through insulation. However, modern machines and systems need a truly isolated, clean and stable power requirement. This is ensured by an Ultra Isolation Transformer (UIT). It provides for total electrical and electro static isolation with most effective screening of spikes, surges and transients. Further, it gives a true isolated local neutral and dedicated earth which are very essential for modern machines.

The circuit uses single phase inverter cum charging transformer with multi tapping AC output terminals for Relay type Buck-Boost stabilizer to provide single Phase stabilized AC output voltage, MOSFET based digital controlled  UPS with square wave AC O/P with overload protection, Relay changeover circuits, Automatic trickle Battery Charging circuit, LED indicator for line voltage, UPS voltage and Battery charging, maximum test points to observe the intermediate circuit effects. Ratings- UPS Type - OFF-LINE, O/P AC Voltage - 230V /50Hz, O/P Cycle Nature - Square type or Cosine type, O/P Frequency - 50Hz, Back-Up Time - 15 minutes, O/P Wattage - 500VA, Battery Charging Voltage - 12 V, Battery Charging Current - 5Ah, Battery Type - 12V Rechargeable maintenance free.Objectives : To Study Principal of UPS.
