Avi's page for iRobot Roomba 5xx power supply mod
How did I convert iRobot Roomba 5xx power supply from 110VAC to 220VAC / 240VAC mains ?
How did I make a US / American iRobot Roomba 5xx power supply to work in European countries ?
How did I mod (modify) iRobot Roomba 5xx power supply from 110VAC to 220-240VAC ?
I didn't want to buy/use a voltage converter for this power supply and since I have some basic
electronics knowledge and soldering skills, I moded this power supply.
* Please note that there are few PCB models for the same power supply,
this page relates ONLY to the PCB model shown in the following images which is of iRobot model #: 17062
This mod is NOT recommended by me
nor by iRobot and will void product warranty !
if you follow this mod, you do it on your own risk !
In order to mod this power supply, you'll need to:
A. Disassemble the PCB from the housing

B. Replace 3 components on PCB:
|_Electrolytic capacitor 47µF 400V (marked C1 on PCB)
Note: Take extra care to capacitor polarity when you place it
_Varistor 14D361K , VMax=360 Imax=6000 (marked RV1 on PCB)
|_Time Delay fuse 1.6A 250V (marked F1 on PCB)|
_For safer and secure operation, cut the US plug and add a mains plug according to the standard used in your country.
The US supplied wire comes without earth wire so you don't need to worry of it.
