For Your Information: Transformer Technology

What are Magnetic Transformers?

These transformers use two coils, a primary coil and a secondary coil, to reduce the voltage from 120 volt down to 12 volts. The primary coil carries the line voltage (108 v to 132 v). The flow of electricity through the primary coil induces a magnetic field that creates a current in the secondary coil. Since the secondary coil has 10 times fewer windings, it creates a current with 10 times lower voltage.

Two Magnetic Types. There are two types of magnetic landscape lighting transformers. These vary by the type of core:

  1. Laminated/stacked cores (also know as EI type). Laminated or stacked windings have sheets wrapped in copper wire that are then stacked or laminated together to make a core. This is the more common, less expensive method for manufacturing a core. These are less efficient, run hotter and are noisier than toroidal cores.
  2. Toroidal cores. These are one solid unit shaped like a donut and have the windings wrapped around the donut, in and out of the donut hole. Toroidal cores are more efficient, experience less buzz, and run cooler but are more expensive to make.

The choice of whether or not to use a toroidal core also depends the system load. Systems with relatively high loads - such as lighting systems with 10 or more fixtures, benefit the most from toroidal cores; smaller systems - such as those with less than 50 watts of load, are served well with EI laminated types. This is why VOLT® sells its smallest transformer (75 watt capacity) with an EI core.

What are Electronic Transformers?

This transformer type converts the 120 volt current to 12 volts by first increasing the frequency of the current (from 60 Hz to as high as 20,000 Hz). The increased frequency allows the use of a miniature core enabling the transformer to be very small, light, and inexpensive. The biggest downside is that their high frequency current may not be compatible with LED circuits. These currents also suffer from extensive voltage loss compared to magnetic types. A 12-volt electronic transformer must be positioned within about 10 ft. of the fixture. Electronic transformers are also subject to overheating and premature failure. For all these reasons, VOLT® only uses electronic transformers for indoor lights such as under-cabinet and strip lighting.

  • Q:

    Could you use an outdoor rated z-wave switch instead of a timer or photocell to control these transformers instead of a timer or photocell?

    • VOLT Lighting Specialist

      A:

      Since the transformer is designed to plug into a GFI outlet, you can control the power feed to that GFI outlet. As far as what kind of switch and configuration, you should consult with an electrician.

  • Q:

    Hi there
    Tonight my lights went out.
    I checked everything and it seems that the orange on/off switch might be non functioning.
    If I flick the switch off then on the lights come back on.
    I tried this a few times and sometimes, when I going into the on position the lights flicker on/off, then go out.
    I have pushed the switch over hard now and the ligths are staying on, but it seems like the switch is fragile and sensitive.

    Is this normal?
    Should I do anything to fix it?

    thanks

      A:

      This is not normal. That is a breaker and will trip if there is something wrong down the line. There could be a couple of issues, but without troubleshooting, we would not be able to pin point the part that is causing the issue. If you could, please call customer service, and we can figure out the problem and get you back up and running.

Best price for 300 watt stainless steel

I needed to replace an old 500 watt big box home store transformer that quit working. I am also converting to LED bulbs so the drop in wattage is not a problem.

I have four 12 gauge wire runs and planning to add a fifth so I was worried I could not connect all 5 wires to the single Common tap. I considered the $50 more expensive Clamp Connect transformer that has 5 Common clamps. But for $50 less, I figured if 5 wires would not fit in the Common I could combine 2 or 3 runs into a single with wire nuts and need only to connect two wires to the common. I was pleasantly surprised to see how large the screw clamps are on this unit. I easily got 4 wires in the Common and could get at least 4 more I think. Check out the attached pic.

I also like how the terminal block is angled so the bottom is easier to see when inserting wires. Stainless steel is a plus, looks nice and will not rust.

I recently installed this unit and while the quality seems very good I did have a couple of issues.

After reading the directs and trying to connect the wires to the taps I discovered that 3 of the 4 taps were so tight that I could not loosen them. The screw head slots were not deep enough so the screwdriver could not get a grip and kept slipping off. I was able to loosen just one of the taps to use.

issue two was the timer, when inserted all the way in the socket it would not work, after playing with it some more I discovered that if I pulled it out part way it would operate . I am not sure if it is the timer or the socket that is the problem but it is working and after installation I do not want to have to take it all apart. Just so everyone knows that there are issues and a way to get around them , if you only plan on using one tap of the four.

At least the quality of construction of the unit seems better than anything being sold at the box stores but I guess time will tell

Comments about VOLT® 300 Watt (12v-15v) Multi-Tap Low Voltage Transformer for Landscape Lighting:

Super nice high power transformer at a reasonable price. As I have said of other Volt products I like things that were designed right. These are bulletproof like many of their products. Plenty of poop for a lot of LEDS. The multi tap allowed me to match intensities of other zones perfectly! I ordered the unit with photocell and timer. Easy to hook up. One disappointment was the female thread on the photocell did not have a short nipple for a 3/4 in pipe. Please add that as an option, caused me headaches. Overall well worth your money.

Comments about VOLT® 300 Watt (12v-15v) Multi-Tap Low Voltage Transformer for Landscape Lighting:

I bought a 300 w step down unit and was/am impressed by its construction. I love stainless exterior fixtures! It seemed to be just what I needed but I had a question about how much current it drew during the day (when no load was being drawn by my post lights) when I heard that "hum" when I plugged it in. I found my trusty meter - the kind that passes a loop around a live line - and measured that the transformer was drawing about 3 watts (yep, the same amount that one of my nite-lights draws) when the lights aren't on. So no worries.

If you're adding exterior lighting, these are the guys that you want to be dealing with.

This is a quality product at a fair price. I'll recommend it to friends, and I'd buy it again.

I replaced two 20 year old transformers that had begun to fall apart with this product. I was very happy with how quickly it shipped and arrived. The documentation was clear, and installation easy. The form factor is smaller than what I replaced, and once the plants grow up a bit, it will be easily hidden from view.

Comments about VOLT® 300 Watt (12v-15v) Multi-Tap Low Voltage Transformer for Landscape Lighting:

I live in Central Florida, the "lightning capital of the U.S." I have had four "big box" type integrated low voltage transformers fry during thunder storms. This has been the most active rainy season I have experienced since moving to Florida 11 years ago. There have been strong afternoon thunder storms almost every day over the last two months and my Volt 300 watt low voltage transformer has weathered these storms without a hiccup. I am very impressed with the quality, durability and flexibility of this transformer. Lower quality transformers have their clock timers integrated in the transformer. When the clock fries due to a voltage surge, the transformer is rendered useless. Volt offers electronic and manual clocks that can be replaced if damaged by lightning (My manual clock has weathered every storm so far this year). This is a great product and I highly recommend it for anyone looking for a dependable, high quality low voltage transformer.

I live in Central Florida, the lightning capital of the U.S. I have lost 5 low voltage transformers to lightning over the last few years, each being either Malibu, Hampton Bay, etc. These integrated transformers do not tolerate the voltage surges generated by thunderstorms very well. I recently discovered Volt. The Volt 300 Watt transformer's quality and build far exceed the "big box" transformers. This has been the most active rainy season we have had in Central Florida in years and my Volt transformer has performed flawlessly. I could not be more pleased with it.
