DVB01/digital display window voltage comparator/voltage measurement/charge and discharge/overvoltage and undervoltage protection

DVB01description introduction 

DVB01moduleIt is a multifunctional voltage monitoring controller that uses an industrial grade microcontroller as the main control unit, with a wide measurement range and high accuracy. The controller is pre-set with 5 different functions and can be customized and added with other specific functions according to user needs.

Module procurementuseCarefully processed and manufactured componentsStable performance, can be widely used in various fieldsVoltage measurement controlProduction occasions. 

Features:

oneProvide 5 functions for users to choose from, meeting more application needs;

twoUsers can set the upper and lower voltage limits;

threeMeasurement range: DC 0-100V, measurement accuracy:+/-0.1V;

4. Add automatic power-saving function, which users can set independently;

5. All setting parameters can be automatically saved, and the settings will not be lost in case of power failure.

6. Added 0-99.9-second delayed closing and 0-99.9-second delayed disconnection functions.

onemodulefunction

Users can choose one of the following 5 functions to set and save function parameters. After the parameter settings are completed, they will be automatically saved and will not be lost in case of power failure.

Function 1:Voltage measurement: Select this function, the relay will not operate, and the digital display will show the current measured voltage;

Function 2:Charging monitoring: When the measured voltage is lower than the lower one of the preset voltages V1 and V2, the relay is closed, and when the voltage is higher than the higher one of V1 and V2, the relay is disconnected;

Function 3:Discharge monitoring: When the measured voltage is higher than the higher of the preset voltages V1 and V2, the relay is closed, and when the voltage is lower than the lower of T1 and T2, the relay is disconnected;

Function 4:Inter interval closing: When the measured voltage is between V1 and V2, the relay closes, and in other cases, the relay opens;

Function 5:Off range closing: When the measured voltage is lower than the lower one of the preset voltages V1 and V2, or when the measured voltage is higher than the higher one of the preset voltages V1 and V2, the relay is closed; In other cases, the relay is disconnected. 

Reminder: The controller will automatically determine the preset voltage V1 and V2 based on different functions, which is the upper limit voltage and which is the lower limit voltage. Users do not have to worry about who is larger or smaller, or who comes first or later when setting.
