Relais voor startmodi ster-driehoek (ERV-YU)

Het ERV-YU startrelais is ontworpen voor automatische besturing van het starten van elektromotoren in de STAR-TRINAGON modus bij een bedrijfsspanning van 24/220 V AC. Het relais zorgt voor een zachte start van de motor, vermindert de aanloopstroom en verlengt de levensduur van het hele aandrijfsysteem. Het is uitgerust met een lichtindicatie voor de modi ON, STAR en TRIANGLE en maakt het mogelijk om de opstarttijd in te stellen.

Beschrijving en werkingsprincipe

Voor een soepele start van de elektromotor wordt eerst de STAR-modus geactiveerd, die de initiële stroompiek vermindert. Wanneer de vereiste snelheid is bereikt, wordt de wikkeling automatisch overgeschakeld naar de TRIPLE-modus, waarin de motor normaal blijft werken.

Automatische modusschakeling door relais en schakelaars verhoogt de stabiliteit van het hele systeem en elimineert de risico's die gepaard gaan met handmatige bediening.

Wanneer er spanning wordt gezet op de klemmen A1-A2 van het relais:

  • Het STAR-contact wordt geactiveerd, de STAR-indicator licht op en het opstartinterval t1 (0,1-30 s) begint te tellen.

  • Nadat de tijd t1 verstreken is, wordt het STAR-contact verbroken, gaat het lampje uit en begint een korte pauze t2 (15 ms).

  • Vervolgens worden de FASE-TRIANGLE contacten ingeschakeld, gaat het TRIANGLE lampje branden en blijft het relais in deze modus gedurende de hele tijd dat er spanning op de klemmen A1-A2 staat.

Gebruik

Het ERV-YU relais is geschikt voor:

  • automatische aansturing van motorschakelingen in sterdriehoekmodus

  • industriële toepassingen met hoge eisen voor stabiel en veilig starten van motoren

  • systemen waar het nodig is om de aanloopstroom te verminderen en het elektrische netwerk te beschermen

Aanvullend assortiment

Voor het relais kunt u het volgende aanschaffen

  • magneetschakelaars en starters

  • magneetschakelaars met mechanische vergrendeling

  • stand-alone mechanische vergrendelingsmodules

  • metalen behuizingen met IP65-bescherming

Dit alles is direct uit voorraad leverbaar tegen concurrerende prijzen.

Skye's Absolute Favorite Ball! 🐾
Size: 1 Pack, Style: Ball
Hello, I am Skye! I am an Australian Mountain Doodle puppy, and my humans finally found a ball that can keep up with me! The Benebone Natural Rubber Dog Ball is officially my prized possession. Why I give it five paws: The Perfect Chew: It is made of natural rubber, which means it has this amazing, springy texture that feels so good on my teeth. It's super tough, but it still has a satisfying squish when I chomp down on it. Funky Bounces: Because of the rubber and the design, it doesn't just roll in a boring straight line. When it hits the floor, it bounces all over the place in crazy directions, which makes chasing it so exciting. Easy to Carry: The texture makes it really easy for me to grab with my paws and hold onto in my mouth, even when it gets a little slobbery during a long game of fetch.

So far this is the perfect alternative to other wobble toy feeders. Please make a bigger size!
Size: 1 Pack, Style: Pawbler
Why did you pick this product vs others?: I bought the Pawbler because the two most popular wobble treat feeders on the market are plastic, and one of my dogs just absolutely destroys those in no time because he bites them and throws them rather then nudging them and then he has plastic cutting him so I am forced to throw away a costly treat toy/dispenser. I thought maybe a rubber one would work out better. So far my dogs love it, it works well spitting out their kibble, seems to be holding up and is easy to clean and feels like a good weight, not a super flimsy toy. I would love to see it made in a slightly larger size, I think this current size is good for medium dogs. It holds just under a cup of small round kibble but I would like to see one that can hold more and is slightly larger in size. I have 4 german shorthaired pointers, my test subject for this toy is mostly my 70 pounder who bites the toys instead of nudging them and throws them across the room, so it is taking a beating. I think for him a larger size would be helpful in deterring that behavior but I also think this may be too small for larger breeds. Durability: So far this toy looks just like when I bought it. It has no punctures or scratches and unscrews without problem. We have only had it a week or so but we use puzzle/toy feeders to feed our dogs lunch every day so it is pretty easy to tell which toys won't last long. Obviously, I can't speak to long-term durability at the moment, but I can say that most toys similar to this end up already scratched or punctured in a few days, so this is already sturdier when compared to what I have tried before.

Well made and durable, not a toy the pups seek out
Size: 1 Pack, Style: Tug
Well made. Thought our staffies would love since they live tugging with each other. Sadly not something they seek out. We love ALL the benebone chews though!

Durable fun enrichment toy
Size: 1 Pack, Style: Pawbler
I had been wanting to buy one of these kinds of toys for some time but thought that the other brands I had seen were too pricey so this was a great compromise for the price. My 5 yr old Portuguese water dog loves it. He spent 25 min playing with it the first day. The trick is to find a treat that is just big enough where it doesn’t fall out right away so it makes it challenging and fun for them. He has been chewing on it a lot for a week and it has not broken or shown signs of damage. One thing to note is that there is a small hole on the bottom of the toy so you cannot freeze liquids in it without covering the hole in some way so that would be my only complaint. Besides that it’s a great toy that keeps him busy and happy.

Dog doesn’t care for it
Size: 1 Pack, Style: Bone
Hard to review product for its durability because my dog has never chewed it once. Doesn’t care about it at all. The bone feels rugged but smells like playdoh. It’s sat on the floor for over a month untouched.
