Feature

●Auto save: all setting parameters can be automatically saved, and the setting content is not lost when the device is turned off.
●5 different functions: the controller provides 5 different functions and can adjust and add other specific functions according to the needs of the user.
●Industrial micro controller: the voltage monitoring module is a multifunctional voltage monitoring controller that uses an industrial-grade microcontroller as the main control unit.
●Adjust the upper and lower limits – the user can adjust the upper voltage limit and the lower voltage limit. Measuring range is 0-100V DC, measuring accuracy +/-0.1V.
●Automatic energy saving – increase the automatic energy-saving function, the user can set it autonomously.


Description

Specification:
Item Type: Voltage Comparator
Material: PCB.
Model: DVB01.
Application: digital display window voltage comparator/voltage measurement/charging/discharging/over-voltage and undervoltage overvoltage overlimit protection
Working voltage: DC 5V/12V/24V (should not exceed +/-10% of rated voltage).
Working current:
Less than 90mA at 5V (less than 12mA when relay is not working, less than 3mA when relay is closed)
Less than 35mA at 24V (less than 12mA when relay is not working, less than 3mA when display is closed)
Working temperature: recommended -20°C - 60°C (limit range -30°C - 70°C).
Measuring range: 0-99.9 V.
Load capacity:
Maximum load capacity of the relay closer port: DC 0-30V/10A, AC 0-250V/10A.
Maximum load capacity of the opener connection of the relay: DC 0-28V/10A, AC 0-125V/10A.

Module function.
Function 1:
Voltage measurement: choose this function, the relay does not work and the digital tube shows the current measured voltage;
Function 2:
Charging monitoring: when the measured voltage is lower than the lower limit voltage, the relay will pull, the upper limit voltage is higher, and the relay will be disconnected;
Function 3:
Discharge monitoring: when the measured voltage is higher than the upper limit voltage, the relay attracts, lower than the lower limit voltage and the relay is disconnected;
Function 4:
Interval in interval: when the measured voltage is between the upper limit and the lower limit, the relay is closed and in other cases the relay is disconnected;
Function 5:
Interval external tightening: when the measured voltage is lower than the lower limit voltage or the measured voltage is higher than the upper limit voltage, the relay will pull; in other cases, the relay will be disconnected.
