Your regular UK socket outlet is rated at 13Amps which signifies probably the most power you may
draw from a UK outlet is 3KVA, or 3KW. (Power Measurement will likely be covered within a
separate paper). Above this level (for specialist equipment, or hardwired installations) most UPS is
going to be online double conversion technology because the economies of scale start out creating
other technologies non price effective. Under this level, nevertheless all technologies are offered,
while above around 2KVA, line interactive systems start out to come to be heavy and unwieldy
resulting from the size of transformer that's expected.
In case your load is created up of laptop kind power supplies, then both square wave and sine wave
products will power this equipment adequately. In case your load consists of motors, transformers,
pumps or other inductive elements (around the input power provide) then square wave systems are
certainly not appropriate and also you should opt for a sine-wave system.
Any load that is certainly susceptible to mains disturbances for example in analytical equipment or
audio applications should really also opt for a sine-wave system. Exactly where mains distortions
impact equipment efficiency then you must opt for online double conversion exactly where a pure
sine-wave is often present.
