Product Highlights- Functions: -current detection resolution can change the parameter of resistance parameters; -output over-current switching signal output; -over-current signal setting critical point adjustable,
- Using instructions: by setting the potentiometer to set the overcurrent protection point, the clockwise adjustment reduces the detection current. as bellows: 1. measured the wire through the current transformer , connect vcc and gnd to dc12v power supply; 2. adjust the potentiometer, when you hear the sound of the relay pull (can be measured with a multimeter com and no...
- Features: 5a over-current protection sensor module uses current transformer to collect the ac signal to achieve the relay over-current signal output within 0-5a. relay pull while over-current, relay released while not over-current. users can use the relay com, nc, no three ports to control the external circuit on and off, in order to achieve over-current protection
- Specifications: operating voltage: dc12v operating current: <20ma operating frequency range: 20hz ~ 400hz output mode: switch signal output maximum detection wire diameter: 5.2mm mounting hole: hole diameter is 3mm, hole distance is 52.5mm operating environment: -40 ℃ ~ +85 ℃ the current detection range :ac0.3a-5a board size: 38 * 44mm
- Then reduce or cut off the current flowing that through the tested wire , if the relay release at this time that over-current protection point has been identified (available to multimeter com and nc measurement whether is connected, if connected to the relay means been released); 3. when reduce or cut off the current flowing through the wire , the relay is not released,...
