Power Supply Info

This is information about power supplies (adaptors).

You must pay special attention voltage, amps, polarity and connector type.
If you just connector any adaptor to your electronic device you could burn it up.

Voltage, amp and polarity requirements are usually listed on the electronic device.
You can use an adaptor that has a higher amp rating but not a lower rating.
  example; 9VDC 200mA required adaptor.
  you could use; 9VDC 500mA or anything 200mA and higher.

Never connect a different voltage supply to your device.
  Example; If your device requires a 9VDC adaptor don't connect a 6VDC or 12VDC adaptor.
                  That will burn up you electronic device.

Never connect an AC adaptor to DC device or DC adaptor to an AC device.
Power supplies come in two types AC or DC; You must get the right adaptor.

AC adaptors do not have polarity.
DC adaptors do have polarity.  You must use the adaptor with the right polarity.
 

Symbols	There are two important symbols to note. AC / DC AC is sometimes shown as;    ~ DC is usually shown as two parallel lines top having spaces;   =
Polarity	AC adaptors don't matter, DC connectors are critical. DC is shown like the pictures here.
Types of Connectors	This can be tricky because there are so many different types. You must get the correct connect to fit into your jack assemble on your device. Some types of connectors are displayed here; Note that some connectors are color coded. Standard connectors are 5.5mm in diameter and come either straight or 90 degree bends. Some devices require a 90 degree connector.   Others are 90 degrees;   90 Degree extended connector;   1/8 inch connector;
