2in1 DC 0-100V Voltmeter Ammeter With DC 100A 75mV Ampere Shunt Dual 0.28″ Red Blue Voltage Detector Current Indicator

2in1 DC 0-100V Voltmeter Ammeter With DC 100A 75mV Ampere Shunt Dual 0.28″ Red Blue Voltage Detector Current Indicator

This module uses two high-quality digital LED, high brightness, and can simultaneously display current and voltage.

This module uses imported MCU sampling and display current and voltage, and the software has a lot of data processing, the display precise and stable.

Features:

• This module is a full-chip technology, exquisite workmanship, while ultra-small. This module has reverse polarity protection, even reversed, it will not damage the module.
• 50A and 100A range meter is accurate to 0.1A.
• This mode can be used for monitoring the current and voltage of cars and electric bike batteries.
• For other occasions where need to monitor the DC current.

Lead defined (5 lines):

• Thin black line: header to the negative supply
• Thin Red Line: header to power the positive (red line between fine and thin black line voltage is 4-30V, if exceeded will burn)
• Thick red line: measure positive voltage input (the voltage between the thick red line the thick black line which is between the voltage meter display)
• Thick yellow line: measure the current flow lead.
• Thick black line: measuring current outflow lead (The thick black line and the thin black line are the common ground and communication)
