100v /10A DC LED Current Voltage Vd45204x

Functional set voltage meter in one, measuring current power from the measuring circuit, does not require a separate power supply isolated power supply, easy to use. Affordable only 10 a few dollars you can have a fully functional voltage meter. 33V Variable Precision representatives : measuring stalls below 10V voltage measurement resolution of 0.01V, 10V with a resolution of more than 0.1V. If the measured signal is below 30V and can be used directly as a module supply adequate power supply (the thin yellow lines and thin red line in parallel).

The Thin Red Line (VCC): Power supply input positive (3.5-30V)
Thin black line (GND): Power supply input negative (3.5-30V) and the measurement signal common ground
Thin yellow line (VIN): measuring signal input positive (0-100V, 100V version) (0-33V, 33V Version)
Thick red line (I +): Current input positive (negative power supply must be connected in series)
Thick black line (I-): Current input negative (negative power supply must be connected in series)
