 I  have  two  Rena  110  v  cansiter  filters  running  on  my  tanks.  1  is  over  5  years  and  the  other  is  been  running  for  about  3  years  now.
 I  am  using  the  local  convertors  and  have  not  faced  any  issues  so  far.  They  run  24x7  on  my  tanks.
 
 hope  this  helps..

 well  the  controller  i  sent  back  to  usa  but  there  are  pumps  which  my  sis  had  bought  from  usa.  not  used  yet  but  will  use  them  now  with  converter.  have  you  guys  ever  checked  Hz?  i  read  that  you  get  step  up  step  down  converters  which  help  you  with  Hz.  usa  is  60Hz  and  ours  is  50Hz.

 well  never  bothered  about  the  hertz..  i  only  bothered  about  the  volts.  dont  know  if  i  was  lucky.
 
 (  But  thinking  of  hertz  i  really  dont  know  if  we  get  anywhere  close  to  50  hz  at  our  homes..  my  uncle  used  be  a  chief  operations  engineer  in  one  of  the  thermal  plants  in  chennai  and  he  had  a  monitor  at  his  home  which  monitored  a  few  things...one  of  the  display  was  for  hertz  and  i  never  saw  it  gove  above  30-35  hz  and  this  was  right  at  the  source  where  
 electricity  was  produced.  this  was  again  a  govt  run  plant  a  decade  or  so  back...  not  sure  if  things  are  different  now  )

 Hmm...35Hz  doesn't  sound  right.  The  mains  frequency  should  not  vary  too  much  (the  Voltage  may  vary  though).  This  is  because,  even  though  most  of  the  the  appliances  in  our  homes  can  handle  greater  variations  in  frequency,  greater  variations  kill  the  whole  power  grid.  
 
 The  power  grid  on  the  whole  runs  lock-step  at  the  same  frequency.  If  the  frequency  falls,  it  means  the  load  on  the  grid  is  high.  If  this  is  not  brought  under  check,  the  generators  at  the  power  plants  need  to  work  harder  to  get  raise  the  output  (remember  how  the  whole  grid  operates  at  the  same  frequency?).  This  can  cascade  into  rolling  failures  to  all  the  generating  stations  connected  to  the  same  grid.
 
 This  web  page  shows  the  real-time  frequency  of  the  UK  power  grid  and  also  explains  why  maintaining  the  frequency  is  so  important.  Notice  how  the  extreme  ends  of  the  scale  are  only  4Hz  apart  (48Hz  to  52Hz).

 though,  please  correct  me  if  I'm  wrong.

 Don't  worry  about  the  frequency.  Make  sure  you  have  the  voltage  right.

 Nanomania  frequency  of  electric  supply  is  decided  at  the  power  generation  stage.  I  dont  think  there  are  any  devices  to  change  the  frequency.  Any  equipment  designed  to  run  at  60Hz  can  run  on  50Hz  but  over  a  period  of  time  they  stop  working.  My  experience  is  with  the  motorized  dental  cleaners  of  ORAL  B,  which  I  get  from  US  but  they  dont  last  more  than  a  year  in  India.

 always  try  to  go  for  products  which  are  rated  for  universal  ac  voltage  between  85~265VAC.  As  you  have  already  got  them  you  can  try  to  use  with  some  step  down  voltage  stablizers.
