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

Features

• 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
