UPS types

Identify the right UPS system for your specific requirements.

UPS topology indicates the basic nature of the system’s design. Various vendors produce models with similar designs but with very different performance characteristics.

The most common UPS system designs on the market include:

1. Standby UPS

Also known as offline, standby UPS systems are an adequate choice for small, less critical applications, such as isolated PC’s and peripherals. Almost all standby UPS systems will switch to battery fast enough to give backup power through most outages. It’s important to note that these systems offer limited protection to spikes and sags in the mains power.

2. Line Interactive

This design will give highly effective power conditioning along with its battery backup. Which is a great option for locations where power outages are rare, but there are frequent power fluctuations.

Line interactive UPS systems have voltage boost circuits which will boost and clip high and low voltages, giving a constant output voltage.

Surges and spikes are also eliminated more efficiently than with an offline UPS system.

3. True Online Double Conversion

Online UPS systems provide the highest levels of power protection, conditioning and UPS backup available. Ideal for high speed data transmissions and switching equipment. There is no switching from mains to battery, which eliminates switchover time issues.

The power in this Online UPS design is far superior to that of the other types of UPS as it completely regenerates the sine wave, in order to recondition the raw mains supply.

Online systems also provide frequency regulation, which is essential for use with backup generator systems. Some Online UPS systems can also be used as Frequency Converters for 60Hz requirements.
