ماژول نمایشگر دیجیتال ولتاژ و جریان 100V / 10A DC

Features:
Functional in one set of voltage meter, measuring current supply from the measuring circuit does not require a separate power supply isolated power supply, easy to use.
Compact (48mm * 29mm * 22mm) to believe that the market is already the smallest voltage meter.
Affordable only 25 yuan can have a fully functional voltage meter.
Voltage & ammeter basic performance parameters are as follows:
Opening size: 45mm * 26mm (opening directly into the card table panel)
Dimensions: 48mm * 29mm * 21mm
Supply voltage: DC3.5-30V (thin red line thin black line positive and negative)
Weight: 20 g / only
Display: three 0.28-inch dual LED digital tube
Display color: Red + Red
Refresh rate: about 500ms / times
Accuracy: ± (1% + 2 words)
Voltmeter Range: DC 0-100V (resolution 0.1V)
Ammeter Range: DC 0-9.99A
Note: When measuring the current time exceeds 6A will lead directly welded to the outlet line in order to avoid contact resistance caused by high job insecurity

Onboard wire Function:

The Thin Red Line (VCC): Power supply input positive (3.5-30V)
Note: If the measured signal is below 30V and sufficient power can be used directly as a power supply module (thin yellow line and the thin red line in parallel)
Thin black line (GND): Power supply input negative (3.5-30V) and the measurement signal common ground
Thin yellow line (VIN): measuring signal input positive (0-100V)
The crude red line (I +): Current input positive (negative power supply must be connected in series)
Thick black line (I-): Current input negative (negative power supply must be connected in series)
