Voltmeter Suite Kit 3.5~25V Volt Meter Kit Ic New

Product description:

1. Suite Features.

Suite Name:Voltmeter Suite Type:VOT-8.

Operating Voltage:3.5~25V.

Measuring Range:0~30V Measuring Accuracy:0.1V.

The VOT-8 voltmeter suite is controlled by key-switch and can work well under the condition of two-wire or three-wire system.

For the two-wire system, VOT-8 will be supplied with power by the measured voltage. And the measuring range is 3.5~25V.

For the three-wire system, VOT-8 will be supplied with power by a set of voltage with the range of 3.5~25V. And the measuring range is 0~30V.

2. Principle of Operating.

The measured voltage is inputted via J1 PIN3. And it's inputted to the SCM PIN23 after the pressure resistance through R1.VR1 and R2. The analog voltage will be transferred to digital signal through the A/D converter inside of the SCM. At last, the measured voltage will be displayed on the digital tube after scanning the digital tube.

The system power is connected reversely through S1 polarity. And the IC of diode (from D1 to U2) outputs voltage 3.3 V.
