Digital Panel Meter for Voltage and Current 0-100VDC 0-10ADC

Dual Display Panel Meter, 0-100VDC and 0-10ADC

This handy compact panel meter will display the voltage and current clearly. It is ideal for a bench power supply or any project that requires accurate voltage and or current measurement. The meter can either be powered from the supply it is measuring if it is between 4.5-30VDC or from an independant power source.

Voltage Measurment : 0 - 100VDC

Current Measurment : 0 - 10ADC

Working Voltage : 4.5 - 30VDC

Dimensions : (W)48mm x (H)29mm x (D)22mm

Connetions

Red (Thick) - Voltage in for Current Measurment

Black (Thick) - Voltage out for Current Measurment

Red (Thin) - Supply Positive 4.5-30VDC (connect to voltage to be measured if not using a seperate supply)

Black (Thin) - Supply Ground (Do not connect if not using a seperate supply)

Yellow (Thin) - Voltage to be Measured 0-100VDC

3A DC-DC Step Down Voltage Regulator (Buck Converter)

This tiny step down voltage regulator uses high frequency switching to make a very efficient DC-DC converter. It can take 4.5V to 28V and lower it to between 0.8V and 20V at up to 3A (output). The voltage is set with the small in built potentiometer.

Voltage in : 4.5V - 28VDC

Voltage out : 0.8V- 20VDC

Switching Frequency : 1 - 1.5MHz

Maximum Output Current : 3A

Dimensions : 22mm x 17mm
