Featuring a traditional wound isolation design, it offers superior safety and longevity without electronic failure risks. Its compact size with built-in ventilation ensures efficient cooling, making it a trusted choice for professional-grade low-voltage lighting installations. ## Description this transformer can also used for SET250CK Review: Four Stars - used this in an Optimist electric fire it has been working satisfactory for about 6 months now. Review: Good Quality - If you are going down the route of 12V lamps then clearly you will need a means of getting it. There are two main ways of doing this. A traditional transformer or an electronic one - basically a switch mode power supply. The traditional transformer has some advantages if well made. It will last forever, has nothing electronic to go bang and if you get a proper wound isolation transformer it will ensure galvanic isolation and therefore be very, very safe. The downside is that they can be expensive and the power is always 'on.' Electronic transfomers are cheap, efficient because they only supply power when a load is detected and are usually smaller. The downside is that the won't last forever and it is possible under failure that mains power could end up on the low voltage side. However, in this modern world electronic power supplies are the norm. I bought this because I had a large amount of downlights - 36 - to power up and it was either multiple transformers or being close to the limit on the small normally packaged ones you get in most DIY stores. This transformer will do a maximum of 300W, which is more than able to cover my lighting needs - using LEDs at 4W - leaving spare capacity which will hopefully ensure it lasts a good long time. Size wise, its about the same diameter as a saucer from a cup and saucer set and about 30mm thick. Not too huge but clearly bigger than the average items you normally see. It has got air vents so it has to be mounted in space able to circulate air. Overall, I'm very happy with this solid power supply that drives my LED's well with no flickering or interference. ## Features - Eaglerise SET300CK SET250CK 300W Halogen Transformer ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00DW48JMC | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 72,238 in Lighting ( See Top 100 in Lighting ) 1,547 in Halogen Bulbs | | Certification | CE | | Customer Reviews | 4.4 4.4 out of 5 stars (15) | | Date First Available | 18 Mar. 2015 | | Item Package Quantity | 1 | | Item model number | SET300CK | | Manufacturer | Eaglerise | | Plug profile | Surface Mount | | Power Source | Corded Electric | | Product Dimensions | 12 x 12 x 4 cm | | Wattage | 300 watts | ## Product Details - **Brand:** Eaglerise - **Manufacturer:** Eaglerise - **Mounting type:** Surface Mount - **Power source:** Corded Electric - **Specification met:** CE ## Images ![Eaglerise Halogen Transformer AC230V to AC 12V 300W Power Supply For NV-Halogenlampen led lights bulbs SET300CK - Image 1](https://m.media-amazon.com/images/I/612rS27ETaL.jpg) ![Eaglerise Halogen Transformer AC230V to AC 12V 300W Power Supply For NV-Halogenlampen led lights bulbs SET300CK - Image 2](https://m.media-amazon.com/images/I/61h8lN-K5FL.jpg) ## Questions & Answers **Q: Bought the eaglerise transformer and connected it to 6 x 4w leds, after a few minutes all leds start flickering. anyone and ideas what's causing it?** A: Thing to remember is that this is a switched mode power supple and the DC output is not perfectly smooth. As the advert says, "HALOGEN" . These bulbs use a filament which will not respond to the switching frequency. LED stands for light emitting "DIODE". The diode means it is trying to rectify the ac component of the DC ouput hence the flickering. You need a specific LED power supply for these led bulbs with a smoothed rectified and regulated output. (FYI I have ONC/HNC electronic engineering as a background)Ray **Q: What are the diameter and depth please? I need to replace a 230v 50hz input, 12v output 175va unit which currently supplies 5 X 35w halogens.** A: Hi, the dimensions of the SET300CK are 120mm diameter x 40mm depth with a 12mm centre hole. If you only need maximum 175 watt rating your other option is to use the Eaglerise SET210CS (search on Amazon ID = B007FX1AW2) which has a maximum 210 watt rating and dimensions of 118mm max length x 79mm width x 40mm depth with a central 10mm hole.Hope this helps, let me know if you have further questions. Regards HS **Q: i am in dubai ,we need this item 2 pcs please send delivery time & price with all charge include** A: The costs including shipping 89.75 £ . I can not tell you what Dubai costs customs. **Q: Can this transformer be used with dimmable halogen bulbs?** A: yes ## Customer Reviews ### ⭐⭐⭐⭐ Four Stars *by J***I on 3 March 2016* used this in an Optimist electric fire it has been working satisfactory for about 6 months now. ### ⭐⭐⭐⭐⭐ Good Quality *by M***M on 16 June 2014* If you are going down the route of 12V lamps then clearly you will need a means of getting it.
