Description
Features
Module is connected to power,the voltage can be detected in real time.When you need the phone,IPAD,MP3 and other digital products charge,click the "Output Enable" button,then USB power indicator lights,USB output voltage 5.0V.When you need to turn off the voltmeter,click the "Low Power" button,then enter the ultra-low-power standby mode,USB output corresponding shutdown
Spezifikation
- Voltmeter wide range : DC4.5 ~ 40V
- 5V/2A output current (Only when the input voltage is 6.5 ~ 40V, it can output 5V)
- A key ("Output Enable" button) switch USB output, a key ("low-power" button) to enter the ultra-low power
- Voltmeter can be artificially calibrated, will never exist voltmeter inaccurate problem
- With reverse polarity protection, reverse polarity does not matter
- With over-current, over-temperature protection
- With USB power indicator
- Equipped with terminals to facilitate wiring
- Size: 58mm x21mmx10mm
Applications
Wide input voltage, for car / battery car / motorcycle used for monitoring battery voltage; measure the voltage needed for a variety of occasions
The output current capability 5.0V/2A, enough to meet a variety of USB devices, voltage is very stable.
Two-wire voltmeter onboard self-calibration method :
When the onboard voltmeter normal operation, press "Output Enable" button for two seconds then release, voltmeter flashes, then into the voltage adjustment mode ;
Touch "Output Enable" button, the voltage rises one unit, touch "low power" button, voltage reduction one unit; the voltage value of a unit less than 0.1V, so you need to continuously press 1-5 times in order to see the voltmeter change 0.1V, continuous button several times depending on the specific voltage value currently displayed, the higher the voltage the current display, press the number of the less;
When the voltage is adjusted, press "Output Enable" button for two seconds then release to exit voltage calibration mode, all parameters set to automatically power-down save.
