Description

• It can easily measure the USB port and the small size of the equipment, the working current of the output voltage of the plug without power supply and other supporting equipment, and the standard of the output voltage and current of the USB charger is also detected. It is suitable for factories, laboratories and users .

• Technical index:

• Working range: current (0~2.5A) can detect the qualified voltage of mobile phone charger DC5V

• Business scope: U = 3~7.5V I = 0~2.5A

• Resolution: 10mV voltage and current 1mA

• Error: voltage<±1% current<±2%

• Full scale drop: (when measuring current) 200mV

• The tester uses a new generation of power supply four and a half ~ double cycle integral conversion IC, with high-precision band gap reference, ranging accuracy, high precision, stable and reliable performance, strong anti-interference ability ~ strong anti-interference ability, high temperature resistance, usable It is used to measure the power consumption of USB power supply or interface, mobile phone charger, U disk and other products.
