bayite DC 5-120V 400A Mini Digital Current Voltage Amp Meter Gauge with Hall Effect Sensor Transformer

bayite DC 5-120V 400A Mini Digital Current Voltage Amp Meter Gauge with Hall Effect Sensor Transformer

• Through-hole design: Easy Wiring; Measure positive or negative current; No current direction limitation
• Electrically isolated from high voltage power source which eliminates risk to delicate monitoring equipment and also minimizes safety concerns
• Display Voltage or (+ -)Current; Voltage Range: 5V-120V; Current range: 0-400A
• Compatible with large wire; Diameter of the hole through sensor is 3/4 inch(19 mm)
• Loop through sensor multiple times to strengthen signal. For example, if your current signal is only 0.2 Amps, you could loop the wire through the sensor 10 times and the signal would by 10X stronger and would appear as 2.0 Amps

bayite Hall effect current meter reads current by detecting the magnetic field around the wire, there is no electrical contact which eliminate risk to delicate monitoring equipment and also minimizes safety concerns. The sensor doesn't get hot like the current shunt sense resistor which can have thermal temperature heat dissipation issues.<br><br> <b>Three display modes: </b><br> 1, alternately display Amps and Voltage<br> 2, only display Amps<br> 3, only display Voltage<br><br> <b>Specifications:</b><br> Measurement Range: + -400A<br> Accuracy: + - 1%<br> Resolution: 1A <br> Working Current: 7-15mA<br> Power Supply: DC 5-120V<br> Overall Dimensions: 48mm*29mm*23mm<br> Cutout Size: 45.5mm*25.5mm<br> Inner Diameter of the Sensor: 19mm<br> Operating Temperature: -4°F - 140°F (-20°C - 60°C)<br><br> As the resolution is 1A, the current reading might be flickering with 1A difference. For example, if the current is 15A, you might see a 14A and 16A alternatively. This is normal.<br> If your signal is too weak or you are not getting the resolution you want, you can coil the wire through the current sensor as many times as you want to double, triple, or quadruple the sensitivity or resolution.<br>For example, if your current signal is only 2 Amps, you could loop the wire through the sensor 10 times and the signal would by 10X stronger and would appear as 20 Amps.
