Hello and welcome to our site on the notebook power supply, we hope you find the information that you are seeking while here. PSU or power supply unit is the component in the computer that supplies power to the other components in a computer system. A power supply unit is designed to convert AC electrical power (100-127V in America, Taiwan and Japan; 220-240V in the rest of the world) to usable low-voltage DC power for the components inside the computer system. Some power supply units have a switch on them that allows you to change between 115V and 230V. Other PSUs have the ability sense the level of voltage automatically or are able to accept voltage within a given range.
Most power supply units today are built for the ATX form factor. This gives people the option of swapping and changing different power supplies with different components inside a computer system. All ATX power supplies are also designed with the ability to be turned on or off using a signal that comes directly from the motherboard and also provide additional support for certain functions such as standby mode that is available in most computer systems today. The most recent ATX standard PSU specification as of 2008 is V2.31.

Hi.The start
A few weeks ago I ran into an eBay-auction and won a Scooba 5800, incl. US-charger and an almost dead battery.
So, I got a 110 VAC switching power-adapter in my hands, while -here in the Netherlands (Europe)- we got 220 VAC from our power-outlet.
The idea
So, I'm planning to build myself an European charger (*). But, I got confused by the adapter-plug, which looks like a 3-DIN pins-plug (somewhat like an old AT-keyboard-connector). I've ordered a 220/110VAC-converter, in order to check merely what's going on at the charger / adapter, since I'm very curious about the 3 pins. Well, checking it by a multi-meter, I noticed a GND, 22V DC and a 5V DC at this plug.
The GND is easy to understand, as is the 22 V DC. But what is the 5V DC doing ? I noticed the 5V DC is generated by the Scooba itself. If I unplug it, there's no 5V DC anymore at this adapter 3-DIN pin. Therefore the 5V comes from the Scooba.
Getting puzzled
But, what is the purpose of this signal-pin ? I assume it has to do about a kind of feedback-signal to the charger to continue / stop charging. But something keeps me puzzled about this. I assume that it operates like a kind of relay-mechanism, which is positioned in the charger, controlled / operated by the Scooba.
Control ?
I suggest it might operate like the following :
1) if there's no battery or one of a very bad quality in the Scooba, it can't pull the "relay" in the charger into the "charging-mode".
2) Battery is low, but still has enough to send a 5V signal, which can pull the "relay" in the charger and setting it into the "charging-mode". (And because it's charging, there's enough power to maintain this status / mode)
My question / request
In other words, is the Voltage dropping from 5 V to 0 V DC when the battery is charged ?
Or can anyone tell / confirm me what this 5V DC is for and what it's doing ?
(*) Currently I'm also developing an European timer-based charger for a different Roomba and seems to work pretty well. I use a microcontroller to start charging, which a user can initiate by pushing a button. While charging it's checking the current-load to the Roomba, in order to get a fair impression about the quality of the battery and -if needed- adjusts the charging time of the battery. In other words, it's protecting the batteries from overcharging.
P.S. My native language is Dutch, so I apoligize for my -not so perfect- English / American language. I still hope you can understand what keeps me puzzled.
