Utility power, supplies electricity in the form of sine wave alternating current. When the UPS is in normal mode, it passes the same electrical sine wave to your connected devices. If the UPS switches to operate in battery mode, it either produces sine wave or simulated sine wave electricity to power your electronics.
Galvanic isolation in power equipment refers to the fact that the output power circuit is electrically and physically isolated from the input power circuit. Electrical isolation is accomplished using an isolation transformer. Physical isolation means that the output power wiring does not touch or connect to the input wiring. This is a requirement of international safety agencies in order to prevent shock hazard. Therefore, the addition of another transformer is redundant. Isolation is a feature that can be added to any UPS. The actual benefit of installing an isolation transformer is that common mode noise fed to the computer or equipment is greatly reduced.
In a transformer-based UPS, the Output Isolation Transformer allows the UPS to power loads, such as motors (with four-quadrant drive systems) and industrial devices without disruption.
In a transformerless UPS the short circuit current set by the Inverter usually has the same value whether the downstream short circuit is Phase-Phase or Phase-Neutral. In a transformer-based UPS, the short circuit current value set by the Inverter is greater if the downstream short circuit is Phase-Neutral, as opposed to between Phase-Phase. This higher short circuit current provides improved discrimination downstream of the UPS, even when the UPS is operating without a mains or bypass supply. In its standard configuration, a transformer-based UPS is therefore more suited to installations with long cable runs and several discrimination (protection) levels.
Pulse Width Modulation or PWM technology is used in Inverters to give a steady output voltage of 230 or 110 V AC irrespective of the load. The Inverters based on the PWM technology are more superior to the conventional inverters. The use of MOSFETs in the output stage and the PWM technology makes these inverters ideal for all types of loads. In addition to the pulse width modulation, the PWM Inverters have additional circuits for protection and voltage control.

If more loads are added to a UPS and the new total is more than the rating, the UPS must be able to continue to function. At typical Overload specification is 125% for 10 minutes or 150% for 1 minute. Most loads used in modern equipment, including computers, require a peak current that is much higher than what is required by a simple load such as a light bulb. The UPS must be able to supply this peak current. The Load Crest Factor is the ratio of the peak to the average (RMS) current. The required peak current for supplying computers, for example, is described by the crest factor and can have values of 3.
For 1-PH UPS either of 4/6/15/16 number of batteries and for 3-PH UPS either of 25/29/34 number of batteries could be selected.

Many people are aware of only one type of power problem, a blackout, this is when the power goes out and stays out for a few seconds up to a few days. But there are many more common power problems listed below. Double-Conversion UPS is the only solution of all these problems.
Surge – A brief, but intense, spike in electricity commonly caused by lightning. Surges can damage and destroy electronics, & the intense “spike in electricity” or spike in voltage and current harms circuit boards and components. Blackout – A power outage lasting anywhere from seconds to days. These are most commonly caused by severe weather, utility power shortages, accidents, and power grid failures. Brownout – An intentional or unintentional drop in voltage for an extended period of time. In emergency conditions, power companies may lower the voltage of your electricity to reduce strained resources and avoid a total blackout. Voltage Sags – A sag is also a type of under voltage, but, unlike a brownout, it’s sudden and brief. Over Voltage – Occurs when incoming voltage is higher than normal and lasts longer than a surge but not high enough to be classified as a surge or spike. Frequency Noise – Also known as line noise, frequency noise can disrupt or degrade the performance of a circuit by injecting abnormalities into the system. Frequency Variation – Not a common problem when power supplies are stable, but it can occur when using generators and power frequency fluctuates more than desired. Harmonic Distortion – A departure from the ideal electrical signal on a given power source.
