Description:
1. U
sing high quality materials, durable
2. The voltage alarm module is intelligently controlled by microcontroller with software effect, which can get high measurement accuracy.
3. With buzzer alarm output, can be used for measuring DC voltage, electronic products over-voltage, under-voltage protection, voltage interval control
4. Special DC-DC buck chip power supply, more stable and reliable use
5. Can be widely used in electric vehicles, solar batteries and other battery applications such as overcharge, overdischarge control
Parameters:
Module power supply voltage: DC6- 32V (can be jumpered to set DC5V power supply)
Module operating current: 10mA, 50mA when the relay is sucked, (12V power supply) (different working voltage, the current is different, the higher the power supply voltage, the smaller the current)
Relay control current: 10A MAX can be extended by external relay current
Range: 10V, 20V, 50V, 100V, 300V, 999V, optional. Choose the right range to get the highest measurement accuracy. Distinguish by digital tube side label
Minimum resolution:
10V range: 0.01V
20V, 50V, 100V range: 0.1V
300V, 999V range: 1V
Refresh frequency: 200mS
Digital tube display color: red, yellow
Indicator light: The upper one is red, representing the upper limit alarm indicator. The following is yellow, representing the lower limit alarm indicator
Power supply reverse protection: Yes
Buzzer alarm: Yes (long sound) can be controlled by jumper cap on/off
Calibration mode: software calibration
Operating temperature: -20~+85C
