fosa 20Hz-400Hz 5V 0-5A AC Current Detection Sensor Relay Module with Adjustable Over-Current Signal Seting Critical Point
Senzor za zaštitu od preopterećenja 5
A.Koristi transformator struje za prikupljanje signala ac za postizanje izlaznog signala relej preopterećenja u rasponu od 0-5
A.Relej povlači sa teretom struje, relej je pušten u nedostatku preopterećenja.Korisnici mogu koristiti relej COM, NC, NO s tri priključka za upravljanje uključivanje i isključivanje vanjskog kruga, kako bi se postigla zaštita od preopterećenja.Kritična točka instalacije signal preopterećenja regulirano.Specifikacija : Tip : 5
A 12
V Relejni modul Radni napon : DC12
V Radna struja : Kao сильфон : 1. Izmjerite žicu preko strujnog transformatora , priključite VCC i GND napajanje DC12
V; 2. Prilagodite potenciometar kad čujete zvuk vuče releja (može se mjeriti multimetar, da vidi, je li COM i NO, i ako je priključen na релейные sredstva aktivirana), a zatim smanjite ili isključite struja teče po тестируемому žici, ako relej отпустило u to vrijeme ovu točku za zaštitu od preopterećenja (može se s multimetrom provjerite jesu li spojeni COM i NC, ako su spojeni na relej sredstva su lijek).

- 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) :
