Autotransformer - Split Phase 120/240V - 100AMP

The Autotransformer: for step up, step down and split phase balancing An autotransformer can be used for step up, step down and split phase output balancing purposes. While the step up and step down functions are fairly straightforward, split phase output balancing may require some more attention.

Consider for example a 30A 120/240V split phase supply. The supply could be the grid, a generator or two stacked inverters. Some of the loads connected are 240V, others are 120V. On each 120V leg the load should not exceed 30A. The problem is that as soon as 120V loads are connected, the two legs will show a different current. This is because the 120V loads on the two legs will never be balanced. A 120V 1200W hairdryer, for example, will draw 10A from one leg. A 120V washing machine could even draw in excess of 20A from one leg. Between the two legs the difference in current, or current unbalance, will therefore often be 20A or more. This means that the 30A supply will not be used up to its full potential. By the time one leg draws 30A, the other leg may be drawing no more than 10A, and increasing the 240V load, for example, will result in an overload of one leg while the other leg still has spare capacity. Theoretically, the total power that can be drawn from a 30A 120/240V supply is 30 x 240 = 7,2 kVA. In case of 20A unbalance, the practical maximum will be 30 x 120 + 10 x120 = 4,8kVA, or 67% of the theoretical maximum. The solution is an Autotransformer. By leaving the neutral of the split phase supply unused, and connecting an Autotransformer to create a new neutral, as shown in figure 1, any load unbalance is absorbed by the Autotransformer. In case of a 30A supply, the load can be increased to 7,2kVA, and a 20A load unbalance will result in one leg supplying 40A, and the other leg 20A. The 20A difference will flow through the neutral and the windings of the Autotransformer. The current through both 120V wires of the split phase supply will be 30A.

Temperature protected In case of overheating, the Autotransformer is disconnected from the supply. Reset is manual.Ground relay for use with Multi or Quattro Inverter/Chargers included When operating in inverter mode, the neutral output of the inverter/charger must be connected to ground to guarantee proper functioning of a GFCI. In case of a split phase supply the neutral must be grounded. For this purpose a grounding relay is built in the autotransformers enclosure. The relay is controlled by the 230/240V Multi or Quattro. (The internal grounding relay in the 230/240V Multi or Quattro must be disabled)

An alternative to stacked inverters The alternative to stacking two 120V inverters to provide a 120/240V split phase supply is a 240V inverter with an additional Autotransformer.

SELF TANNERS MUST HAVE!!
Style: Rough Exfoliation
This product is perfect for those of us who use self tanners!! For self tanners to work well and not look splotchy one needs well exfoliated skin and this sponge is exactly the right tool for the task! My skin feels so much softer, my self tanner working much better and my body lotion seems to absorb more quickly. These sponges are easy to hold and have a loop to hang from while they dry. Every week when I wash my towels I toss the sponge(s) into a lingerie bag and wash with the towels. I always hang to dry so no idea how they’d handle a dryer. I will never be without these sponges!

If you like it rough (enough)...
Style: Rough Exfoliation
Perhaps a tad rough for some, the Caveem scrubbers are ideal for me- rough, but not cheese-grater-aggressive. I have been using the first of my two pack for almost three months and, beyond a slight "softening" of the surface, it is in perfect shape- no deformation, no open seams, no tears, thin spots, or defects of any kind. It looks and works like near-new. The sponge is a great size for man hands- basically 6" x 4", and is thick enough to hold ample soap and water to cover quite a bit of skin without reloading. The strap is comfortable and sturdy and, perhaps trivial, but the colors are manly without branding with skulls or wrenches or some other compensatory masculine iconography! I am very satisfied and if they ever wear out, I will happily purchase again.

Good quality for the price
Style: Rough Exfoliation, Style: Rough Exfoliation
Great product for the price! I like a good scrub and this product is the perfect amount of toughness but gentle enough so my skin is not negatively impacted. Its wide although an adjustable strap would have been amazing, its a great size and I appreciate it coming with two!! Easy to use and Holds soap and lather excellent.
