Giới thiệu Rơ Le Cảm Biến Bảo Vệ Dưới Và Dưới 20a

Current detection module specification_20A V1.3
This module is used for detecting current in an AC circuit, and through digital tube display, set the current threshold and the relay delay time through the button, when the detected current reaches the set value, the relay and the delay time for the set time.
Calibration method:1. Module power, the clockwise direction, adjust the RP2 potentiometer so that digital control on the
emergence of digital control, and then slowly adjust the potentiometer, the digital control of the digital display is just 000.2. By adjusting the RP1 potentiometer, the value of the digital tube can be determined by adjusting the value of the current.
working voltage DC 24Ｖ±0.5V.Working current:Before protection less than equal 30mA,After protection less than equal 60mA.Detection range AC 0-20A.detection accuracy Max ±0.2A.Output Switch quantity (Relay output).Size Modules 72mm*69mm*23mm.Belt guide 89mm*71.5mm*55mm
Debugging method
1. Current threshold setting
Long release press SET 3S, digital tube flashing into the state, at this time for the current threshold
setting state, through the + key and - key to set by clicking the SET button to change settings. After
setup is complete, press the SET button about 3S when release this button, the digital tube flashing
out of state. The setting was saved successfully. (The default threshold for the 10A. but because of
the precision, min of not less than 0.2A and the highest is not higher than 19.8A)
2. Output delay time setting
Loosen the long press SET 7S, digital tube flashing into the state, at this time for the output delay
time setting state, through the + key and key to - time setting, change settings by clicking on the
SET button. After setup is complete, press the SET button about 3S when release this button, the
digital tube flashing out state settings success. (The longest delay time can be set to 99.9S, the
default 3S)
Note
The potentiometer on the module is used in the factory , all the modules have been adjusted before
they leave the factory. Please do not adjust it. If the error exceeds the precision after long term
operation, calibrate it according to the calibration method.
