WHAT IS THE DIFFERENCE BETWEEN STANDBY, CONTINUOUS, AND PRIME POWER RATINGS?
Standby power generators are most often used in emergency situations, such as during a power outage. It is ideal for applications that have another reliable continuous power source like utility power. It’s recommend usage is most often only for the duration of a power outage and regular testing and maintenance.
Prime power ratings can be defined as having an “unlimited run time”, or essentially a generator that will be used as a primary power source and not just for standby or backup power. A prime power rated generator can supply power in a situation where there is no utility source, as is often the case in industrial applications like mining or oil & gas operations located in remote areas where the grid is not accessible.
Continuous power is similar to prime power but has a base load rating. It can supply power continuously to a constant load, but does not have the ability to handle overload conditions or work as well with variable loads. The main difference between a prime and continuous rating is that prime power gensets are set to have maximum power available at a variable load for an unlimited number of hours, and they generally include a 10% or so overload capability for short durations

WHAT ARE THE DIFFERENT TYPES OF UPSs?

UPS systems are grouped by topology, which refers to how the UPS and utility power work together. This translates to the level of efficiency and reliability you can expect from your power source.
There are five main types of UPS topologies:
o Standby
The standby UPS is the most common type used for desktop computers. The inverter only starts when the power fails, hence the name “standby.” High efficiency, small size, and low cost are the main benefits of this design. With proper filter and surge circuitry, the system can also provide adequate noise filtration and surge suppression.

o Line Interactive
The line interactive UPS is the most common design used for small business, web, and departmental servers. In this design, the battery-to-AC power converter (inverter) is always connected to the output of the UPS. Operating the inverter in reverse during times when the input AC power is normal provides battery charging.

o Standby-Ferro
The standby-ferro UPS was once the dominant form of UPS in the 3-15 kVA range. This design depends on a special saturating transformer that has three windings (power connections). The primary power path is from AC input, through a transfer switch, through the transformer, and to the output.

o Double Conversion On-Line
This is the most common type of UPS above 10 kVA. In the double conversion on-line design, failure of the input AC does not cause activation of the transfer switch, because the input AC is charging the backup battery source which provides power to the output inverter.

o Delta Conversion On-Line
This UPS design is a newer technology introduced to eliminate the drawbacks of the double conversion on-line design and is available in sizes ranging from 5 kVA to 1.6 MW. Similar to the double conversion on-line design, the delta conversion on-line UPS always has the inverter supplying the load voltage.

UPSs are given a power rating in volt-amperes (VA) that range from 300 VA to 5,000 kVA. This rating represents the maximum load that a UPS can support, but it shouldn’t match exactly the power load you have. To allow room for growth, the best practice is to choose a UPS with a VA rating that is 1.2x the total load you need it to support. If your UPS will be supporting motors, variable-speed drives, medical imaging devices or laser printers, add more VA capacity to your requirements to account for the high power inrush that occurs when those devices startup. Companies that are anticipating rapid growth should use a higher multiplier than 1.2x. Newer server hardware tends to have higher power requirements than older models, so factoring in additional VA will account for adding more and newer equipment.
