DC 0-100V 50A Current Voltage Digital Display Module

DC 0-100V 50A Current Voltage Digital Display Module is a digital panel meter for measuring DC voltage and current. It uses a 0.28-inch LED digital display and shows voltage in red and current in blue. The module supports simultaneous voltage and current display. It is designed for DC measurement in electrical circuits and equipment. An external shunt is required for ammeter use.

This current voltage digital display module includes reverse protection and is intended for panel-mounted measurement applications. It offers clear numeric output for DC monitoring tasks. The display type, measurement ranges, and wiring details make it suitable for users who need a compact digital voltmeter ammeter module.

• Display: three 0.28" LED digital tube
• Display color: A(red+red), B(red+blue)
• Lead Length: 15cm
• Dimensions: 48 x 29 x 22 mm, length X width X thickness
• Opening Size: 46 x 27 mm
• Net weight: 20g
• Working Temperature: -10°C~65°C
• Voltage: 100V DC
• Voltage measurement accuracy: 0.1V
• Current: 50A
• Size: 2.6x2.9x4.8 cm
• Weight: 40g
• Readout rate: 500 ms
• Material: ABS flame-retardant plastic
• Operating temperature: 10- to 85+ °C
• Black line (thin): vacant or buck circuit (module) negative
• Red line (thin): positive pole of power supply
• Black line (thick): COM, common measuring terminal
• Red line (thick): PW+, input terminal of measuring positive voltage
• Yellow line (thick): IN+, the positive of current input
• The voltage between the thin red and thin black lines must be within DC 4.5-30V
• The ammeter can only be connected to the negative of the device under test and can only test amp in positive direction
• Exceeds 5A, long-term full load working continuously, we recommended test side of leads directly soldered to the socket
• When black thin line vacant, it is better to use insulating tape around exposed part of wire to prevent short circuits
• If just used voltmeter, we recommended yellow line and black line connected together to prevent ammeter's digit flashing

How to Use DC 0-100V 50A Current Voltage Digital Display Module

1. Connect the power and measurement wires according to the wiring labels.
2. Ensure the thin red and thin black lines are within DC 4.5-30V.
3. Use an external 75 mΩ shunt for current measurement.
4. Check the display for voltage and current readings.
