HRK 35.37

Dostupno

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) :
