Highlights:

Ultra Wide Voltage Detection
 
Considering the diversity of users'needs, this product adopts ultra-wide voltage detection from DCOV to 200V.
 
The power supply also uses 6V-36V wide voltage range.
 
Suitable for most voltage supply
 
 
 
 
Parameters:
Name: Voltage undervoltage relay disconnection protection module
 
Size: 71mm × 52mm × 31mm
 
Voltage: 6V-36V
 
 
 
 
Features:
 
Wide voltage input, suitable for most voltage supply
 
Ultra Wide Voltage Detection
 
Acousto-optic alarm
 
Optocoupler isolation drive
 
Flexible adjustment of upper and lower thresholds
 
Relay wiring both positive and negative, 10A internal current is completely free of problems.
 
 
 
 
Lower Threshold Voltage = Lower Threshold Voltage * Partial Voltage Ratio to be Measured
 
The threshold voltage to be measured = threshold voltage * partial voltage ratio
 
Preset partial pressure ratio is 42, according to actual measurement.
 
For example, to set the lower threshold of 42V voltage, the lower threshold voltage needs to be adjusted to 1V by adjusting the threshold potentiometer.
 
Similarly, when the threshold voltage needs to be set to 82V, the threshold potentiometer needs to be adjusted to 2V.
