On-line vs In-line UPS Systems
A play on words?
Some companies are fudging their specs to confuse customers, we have noticed this problem mainly in the UPS and inverter fields for example, some companies are throwing the term IN-LINE around in reference to an ON-LINE UPS systems, but on inspection of the UPS systems you will notice it is a line interactive unit, clever marketing !!
Sales swindle or plain fraud, you decide!
We have listed the main UPS topologies here for your reference
Online double conversion
- • Total protection
- • Suitable for generator power
- • Considered up-market
- • Used for sophisticated equipment and servers
Line interactive
- • Limited protection offered by internal AVR
- • Not suitable for generators
- • Used for basic back-up for PC,s and control equipment
Ferro resonant UPS systems (Not recommended)
- • Out dated UPS topology
- • Low efficiency
- • Gives off lots of heat.
We recommend that before you purchase a UPS that you check to make sure that you are getting the correct equipment for the job you require, and remember you get what you pay for, so take time in making a decision.
