Fase beveiligingsrelais - FKV-24F | TENSE

De Fasebeveiligingsrelais van de FKV-serie zijn ontworpen om driefasige apparatuur, vooral motoren, te beschermen tegen fouten die te maken hebben met een onjuiste spanningswaarde, asymmetrie, fasefout of onjuiste fasevolgorde. De FKV-24F werkt in een breed bereik van 180-500 VAC en heeft een vaste asymmetrie van 11%.

Hij zorgt voor een betrouwbare werking van apparatuur die hoge eisen stelt aan de nauwkeurigheid van het vermogen en beschermt deze tegen thermische en mechanische schade.

Functies en werkingsprincipe

Spanningsasymmetrie (11 %)

  • Bewaakt het verschil tussen fasespanningen.

  • Als de asymmetrie groter is dan 11%, schakelt het relais de uitgang na ongeveer 1 s uit en opent het de NO/COM-contacten.

  • Als het verschil daalt met 5 V, beoordeelt het relais de toestand als normaal en hervat de uitgang na een vertragingsperiode.

Fasevolgordecontrole

  • Juiste fasevolgorde → LED OUT brandt, uitgang is actief (NO ingeschakeld).

  • Fasevolgorde onjuist → LED gaat uit en uitgang schakelt over naar foutstatus.

Hoogspanningsbeveiliging (U>)

  • Als de spanning hoger is dan 500 V, wordt de hoogspanningsindicatie geactiveerd.

  • Als de toestand langer dan 2 s duurt, schakelt het relais de uitgang uit.

  • Wanneer de spanning 5 V onder de U>-grens zakt, start het relais een vertraging en hervat dan de werking.

Laagspanningsbeveiliging (U<)

  • Als de spanning onder 180 V zakt, wordt de laagspanningsindicatie geactiveerd.

  • Als de toestand niet eindigt tijdens de foutvertraging, wordt de uitgang uitgeschakeld.

  • Als de spanning 5 V boven U< stijgt, activeert het relais de uitgang opnieuw na een vertragingsperiode.

Statusindicaties

  • 5 LED's geven informatie over:

    • relaisstatus (OUT)

    • hoge spanning (U>)

    • lage spanning (U<)

    • fasevolgorde

    • asymmetrie / fout

Amazing Jewelry Travel Case
I bought this jewelry case for traveling on a cruise and I absolutely LOVE IT! When I purchased it I didn’t know if it would actually fit all the jewelry I wanted to bring but this box definitely impressed me! It fit all my regular jewelry plus more bc you know us woman love to coordinate with our outfits lol the case/box is sturdy! It didn’t break or even dent throughout my travels. It comes with different pieces to help organize and separate jewelry but it is removable if needed which I had to do bc one of my necklaces is really big. The case fit perfectly in my carry on luggage and didn’t take up much room at all which helped me a lot. I got the black case and I just love how simple and sleek it looks. This is definitely a must have if you need to travel with jewelry and are concerned about things getting damaged, this case keeps them safe and it’s definitely a great value for your money!

Great value, great product!
I use this as a home jewelry box - I don't wear a lot of jewelry, so it fits my needs perfectly. Its pretty lightweight and would be good for travels as well. The outside is leather-like and seems to be waterproof so far. I use the first layer for jewelery and second layer to store my hairclips and pins. I've had it for a few months and it seems to be great quality and durable! Definitely a good value as well because I've seen similar jewelry boxes sold at popular retail stores for over $30.

Lovely Slate Gray Jewelry Box
I just received this Slate Gray jewelry box. It's really quite lovely and just the right size for my granddaughter's vanity. I'm really excited about giving it to her, for her 12th Birthday, to hold her better jewelry. It's so nice I'm going to order another one for my other Granddaughter's Birthday.

Songmics Slate Gray Travel Jewelry Box
I purchased the slate gray Songmics jewelry box for travel purposes. We take long vacations and have an upcoming 20 day cruise. I wanted a jewelry box that was compact enough to put in my carry-on bag, but still had room to hold a months worth of jewelry, especially to keep my necklaces for tangling. When this arrived, I was pleasantly surprised and the packaging was great, shipped in a sturdy box. so no damage to the jewelry box. The color is a rich gray and the 2 tier box, while small, holds a lot of jewelry. I wanted to purchase the ink black but could not justify paying twice the price of the gray one just to get it in black. It is small enough that it will fit in most any hotel/ship safe so I won't be sitting out in the room anyway. It has a strong magnetic snap that keeps the box from opening while in transit. The one negative for me is that the pierced earring card is so thick that my earrings barely go through to have enough room on the back side the slip the backs on. I may separate the double thick card, realizing it will not look as nice but will be more functional. The bottom half of the box will hold bracelets up to 1 1/4" wide. There is enough room under the earrings card to place pendants, additional earrings, etc. The necklace holder is designed to hold 5 necklaces, but I added one more by going across the top, end to end, to prevent tangling. I also placed smaller hoop earrings in the ring holder which holds them securely. This box held 7 bracelets, 2 of which were wide, 5 rings, 9 necklaces (I placed 3 in the bottom of the box, and had room for 23 pair of earrings (some placed in the ring holder and in the bottom of the bo)! I would buy this again in a heartbeat.
