Measuring Range 0-100V DC and 1-10A (0.1% Tolerance) *
Operating Voltage 4-30V DC, max. 20mA
On-Module Shunt Resistor 0.075 Ohm
Sample Rate about 3 Samples / Second
Display: 0.28″ LED Blue (Voltage) and Red (Current)
Dimensions: 48 x 29 mm, Thickness 22 mm
Panel Opening: 46 x 27 mm
2 trimmer on the back of the module allow for adjusting the voltage and current reading.
The current zero point can be reset with the following procedure:
– disconnect the power
– shorten the 2 contacts “I_ADJ_Z”
– supply power to the module, and current reading is reset to zero
The thin red and black wires are for the power supply, yellow is the voltage sensing line.
If you want to power the module from the voltage you want to measure, connect red and yellow together to [+] and leave the thin black wire unconnected.
If you have a separated power supply, connect it to the thin red and black wires. Connect yellow to the voltage you want to measure.
Please see the possible circuits in the pictures.
* Current lower than 1A is shown less accurate.
