Latronics LS-2012 - Inefficiency or Noise

OTHER ITEMS
Ineciency or Noise
Some appliances may cause the inverter to run ineciently or more noisy than usual due to the
current waveform they draw.
Certain appliances draw un-even load from a.c. supplies which from a mains supply might
be OK. When operating from an inverter however it may unbalance the internal toroidal
transformer which can cause the inverter to overheat or make undue noise. An example of an
un-even current waveform is below
Some appliances that can cause this issue are
● Hair dryers
● Variable heat guns
● Washing machines
● Dish washers
● Air-conditioners
● Microwaves
This imbalance can be evened out by applying more load or trying a dierent model/brand.
Also ensure that the appliance has RCM compliance as uncertied equipment can put
unnecessary noise back into the inverter.
If you are having trouble with a certain appliance please call Latronics for further assistance.
