DC 0-99.9V Voltage Monitor Module Programmable Delay Relay Switch Controller Battery Protector

1.Description:
A30-U1 is a DC 99.9V Voltage Monitor Module with Delay. It can flexibly set detection upper and lower limit voltage values and set triggering conditions.It can realize functions such as voltage detection, overvoltage and undervoltage control, voltage alarm switch controller etc.

2.Features:
1>.Separated measured voltage and working voltage
2>.Wide voltage monitoring range 0.1V-99.9V
3>.30A high current relay control
4>.Support voltage calibration
5>.Real-time voltage monitoring
6>.Parameter power-off save

3.Parameters:
1>.Product name:A30-U1 DC 99.9V Voltage Monitor Module with Delay  
2>.Work voltage:DC 6V-80V
3>.Measured voltage:DC 0-99.9V
4>.Display voltage:DC 0-99.9V
5>.Voltage calibration value:-0.5V~0.5V
6>.Delay time:1~9minute or keen ON(adjustable)
7>.Work current:4mA~58mA(at 24V)
8>.Output type:Relay switch output(No output voltage!!!)
9>.Load(Max):DC30V/30A or AC250V/30A
10>.Work Temperature:-25℃~85℃
11>.Work Humidity:5%~95%RH
12>.Size:78*53*30mm

4.Set Methods:
1>.Screen display Current Measured Voltage Value automatically after power ON.
2>.Press SET button enter into set mode and the first bit will keep flashing. The first parameter set is the Upper Limit Voltage Value.
3>.Press ENTER button to set first bit value. Its set range is 0~9 as your needs.
4>.Press SET button again to switch select the next bit and press ENTER button to change value.
5>.Press SET button at 3rd time to switch select the last bit and press ENTER button to change value.
6>.Then then first parameter ‘Upper Limit Voltage Value’ has been set.
7>.Press SET button at 4th time to set next parameter the Lower Limit Voltage Value in the same methods. Note: its value needs less than the Upper Limit Voltage Value.
8>.The third parameter is to set the Voltage Verification Value. Its set range is -0.5V~0.5V.
9>.The 4th parameter is to set the Display Screen Automatically Turns OFF Remaining Time Value. Its set range is d-0 ~ d-9 which means after 1~9minute, the screen will turn OFF. Note: d-0 means the screen will keen ON all the time.
10>.The 5th parameter is to set the Relay Triggering Status ‘ON H’ or ‘ON L’.
10.1>.‘ON H’ : Relay output will turn ON if the Current Measured Voltage Value is more than the Upper Limit Voltage Value. Relay output will turn OFF if the Current Measured Voltage Value is less than the Lower Limit Voltage Value. It can be applied to battery discharging mode.
10.2>.‘ON L’ : Relay output will turn ON if the Current Measured Voltage Value is less than the Lower Limit Voltage Value. Relay output will turn OFF if the Current Measured Voltage Value is more than the Upper Limit Voltage Value.It can be applied to battery charging mode.
11>.Automatically enter detection status after set parameters and screen stop flashing.
12>.At normal monitoring status, screen can display time for relay keep ON status in minute after press ENTER button. Stop timing when relay turn OFF. Restart timing if relay turn ON again. Keep press ENTER button about 3second can clear time.

5.Application:
1>.Industrial control equipment
2>.Instrumentation test
3>.Experimental data testing and monitoring
4>.Solar and wind power supply system
5>.Electric bicycle
6>.New energy vehicles

6.Package:
 1pcs A30-U1 DC 99.9V Voltage Monitor Module with Delay
