Power supply 9V 1A
It‘s a good quality switching ‘wall wart’ AC to DC 9V 1000mA wall power supply. These are switch mode power supplies which mean the output is regulated to 9V and the capable output current is much higher (1000mA!).
These will power most projects that don’t require more than 1000mA of current. Center-positive 5.5x2.5mm barrel connector.
Input voltage: 110-220VAC
Power input frequency: 50/60Hz
Output voltage: DC9V
Max output current: 1A
Working temperature: -10℃~+50℃
Storage temperature: -20℃～+85℃
Power supply polarity: Inside positive outside negative; inside x(+), outside i(-)
Note: Please make sure the input voltage is in the range or it will blown up. Recommend the use of current is less than 1A, otherwise easily damaged
