30V three wire DC voltage meter head LED digital meter
Product Parameters
Measurement range: DC0V~100V
Screen: 0.56-inch LED screen
Display mode: Three digit 0.56 "LED digital tube
Display color: Red, Green, Blue optional
Power supply: DC 3V-30V (with anti reverse protection)

Product Overview
This voltmeter is compact in size, with a range of DC0V-100V DC. Additional auxiliary power supply is required, with a wide voltage range of up to 3-30V, which can operate at 5V, 9V, 12V, 24V, etc. If only the power supply voltmeter displays 0.00, no voltage stabilization is required. The power supply has reverse connection protection, which prevents overheating when connected in reverse. All display devices use high brightness LED digital tubes. It can be used to monitor battery voltage, timely grasp the battery voltage status, and can also be used for voltage measurement of other products.
