A preko-trenutna zaštitu senzor modul.Koriste trenutni trafo da pokupim AC signal postići relej preko-trenutna signal izlaz u 0-5
A.Relej povući dok preko-trenutna, relej oslobođena dok ne završi-struja.Korisnici mogu koristiti relej COM, NC, NE tri luke za kontrolu vanjskom krugu .. na i van, u cilju postizanja preko-trenutna zaštitu.Preko-trenutna signal postavljanje kritičnom trenutku je prilagodljiva.Specifikacija : Tip : 5
A 12
V Relej Modul Radi napon : DC12
V Radi trenutni : Kao bellowsa : 1. Mjeri žicu kroz trenutni trafo , povezati VCC i GND da DC12
V napajanje; 2. Podesite potentiometer, kad čujete zvuk relej povuci (mogu se mjeriti s multimeter, da vidim da li COM i NIJE bio uključen i ako povezan sa relej znači aktiviran), onda smanjiti ili odsjekao trenutne teče kroz testiran žicu , ako relej objaviti u ovom trenutku to gotovo-trenutna zaštitu poenta je identificiran (mogu koristiti multimeter da vidim da li COM i NC je povezano, da je povezan sa relejne znači pušten).

- Functions:
- Current detection resolution can change the parameter of resistance parameters. :
- Output over-current switching signal output. :
- Over-current signal setting critical point is adjustable. :
- Board Description:
- VCC:
- Operating voltage positive;
- GND :
- Operating voltage negative;
- NO:
- Normally open, the relay pulls before the NO and COM disconnect, short-circuit after the suction;
- COM:
- common, relay common interface;
- NC:
- Normally closed, the relay before the NC and COM short-circuit, after pull off.
- Using Instructions:
- By setting the potentiometer to set the overcurrent protection point, the clockwise adjustment can reduce 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, to see if COM and NO was turned on, and if connected to the relay means activated), 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 (can use multimeter to see if COM and NC was connected, if connected to the relay means been released) :
