Voltmeter 0-200V Ammeter 0-10A DC

Technical Parameters:

• Supply voltage :                        4.5-30V
• Measurement range:                  DC 0.00-9.99A(current) 0-200V(voltage)
• Measurement accuracy:                  ± (1%)  

Instruction of wiring

Red thin wire (VCC): Power input+ 4.5-30V (NOTE: If the measuring signal is lower than 30V and have abundant power supply, it can be used as power supply for the module [black wire and yellow wire are contacted together to use])           

Black thin wire(GND): Power input- Measurment signal -  4.5-30V

Yellow thin wire (VIN): Measurment signal+ (0-200V)

Red thick wire (I+):  Current input+ (in series in power supply positive)

Black thin wire(I-):  Current input- (in series in power supply negative)
