The Shunt Resistor is a special type of resistor with small resistance which allows large currents to pass through it. This is useful for measuring the current in a circuit: due to the Ohm’s law and voltage drop on the shunt resistor, we can know exactly which current passes through it. For example, for this resistor whose maximum current is 50A, the voltage drop at that current will be exactly 75mV (0.075V). Using a precise ADC, we can accurately measure the current of our consumer or power source.

• Max. current: 50A
• Voltage drop for max. current: 75mV
• Dimensions: 120mm x 25mm

The digital voltmeter and ammeter measures and indicates current and voltage in 7-segment digits! You can connect it to your power source to see your real-time characteristics or a consumer cost to check its consumption at any time. It measures voltages up to 100V and current up to 10A (shunt resistor embedded). This device is intended for installation in a housing.

Do you want to measure a higher current? Not a problem! The device comes with a cable to connect an additional external shunt resistor that will allow you to measure even higher currents. Shunt resistors can also be found in our store.
