  • Power: 72W (3A) isolated
  • Voltage Input: 24VDC
  • Output Voltage: 24VDC
  • Dimensions: 127 x 87 x 50mm
  • Weight: 440g

The sensitivities of modern electronic equipment to variable input voltages susceptibility to EMC interference and in some cases the need to isolate the supply has made voltage stabilisation an important section of our product range. Start/Stop technology on motor vehicles has added to this problem. The DDi Series offers a wide range of 12V-12V and 24V-24V isolated products that ensure a stable and reliable voltage can be delivered to important equipment even when the electrical system is under duress such as during engine cranking. Units are available from 36-240W. The range now also offers 48V-12V units suitable for the telecoms and forklift truck markets. For 12V-24V converters see DD Series 'Up' Voltage Converters

A Comprehensive Product Range

There are three products in the 12V-12V isolator range from 36W to 108W and a further four products in the 24V-24V range from 72W to 240W. There are also three 48V-12V products from 36W to 108W. All products use modern switchmode designs and are built using the same concepts and technologies as the successful PowerVerter range which will of course meet your 24V -;12V requirements.

Fast Installation

All the units consume an off load current of less than 15mA which is probably less than the self discharge current of the vehicle's battery. All the products fit onto a Click n' fit mounting clip which is fixed in three points allowing it to be mounted onto uneven surfaces. It is easy to fit the clip into awkward places then simply click the unit into position. The green LED indicates when there is output from the converter. This gives reassurance to the installation engineer and speeds fault finding.

Expensive, but Smooth, Sturdy Spice Rack
I received the BOIVSHI Spice Rack Organizer through the Vine program, and overall I’m quite pleased with its quality. The rack feels sturdy and well-made. The metal construction has a solid, heavy-duty feel, and the chrome finish gives it a clean, modern look that works well in most kitchens. The pull-out mechanism is smooth and glides nicely. The 2-tier design is efficient and makes good use of vertical space. Installation was fairly easy and the instructions are simple enough to follow. For me, it is limited to smaller spice bottles, due to the configuration of my cabinet which limits the available height of the top tier. Also, the rack has to be secured to the surface, either with screws or adhesive mount, to prevent it from sliding around. Overall, it is well made and a practical solution for organizing spices. If your cabinet dimensions are compatible and you mostly use standard-size spice jars, it’s a solid upgrade that makes everyday cooking more convenient. However, this is a very expensive spice rack, if you compare it to similar items.

Good size, looks nice, mostly easy to put together and install
Okay I love this a lot more than I expected to. I was not extremely excited about the instructions. They come with a warning that if you have any doubts about your ability to install this, call a qualified technician. It just seemed condescending. Also, everything is printed poorly, like someone put this together in the 80's and it printed smudgingly and this is the copies from that. The only thing that this made confusing was when trying to figure out where the cabinet screws go (before I realized that was an alternative install), you really can't tell which holes they go in. Turns out they probably go in the holes covered by the pre-installed sticky PVC mat. Only other issue I had was that it comes with a screwdriver. It seems so wasteful to include something that should be in every household, especially those who buy diy things like this. But beyond that, everything else is great. It was easy to put together, it was easy to place in the cupboard, and it was easy to fill. I love that each line comes out individually. It's nice and sturdy. I tried pulling on it to test it, and the sticky was strong. I mostly loved that, even though this took up 3/4 of the shelf, I was able to fit all my small spices AND my honey AND my sprinkles. I went from 3 overflowing shelves to 2 full shelves and an almost empty one. I only have 6 items on the top. I feel super happy about this.

Functional and Good Quality
Color: 01-silver, Color: 01-silver
I give this SMARTAKE paper towel holder 4 stars. Overall, it's a very good product that I would recommend, but it has one minor drawback that takes away a star. The Positives Quality and Stability: The holder feels good quality, and the material (steel) is sturdy. Once placed on the counter, it's stable and adheres well to the surface. Assembly and Use: It was easy to put together; just read the instruction manual. I confirm that it works well even with large paper towel rolls. Furthermore, it's not difficult to change the roll at all. The Drawback The only problem is the small mechanism that's supposed to adjust and hold the roll (the piece that prevents it from twisting too much). As the paper gets used up, this piece doesn't do its job properly, and the paper unwinds more than it should. Conclusion: If you're looking for a modern, stable, and well-made holder for your kitchen, this is excellent. Just keep in mind that the adjuster isn't the best, but other than that, it does its job perfectly.
