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:

    Can you connect more than one line run to the 12v connector and common? I would like to be able to connect two line runs.
    Asked on 11/11/2017 by Sailor from Stuart, Florida

    1 answer

    • VOLT Lighting Specialist

      A:

      Yes; the screw-style of the taps within this transformer allow for multiple wire runs to be inserted, and securely fastened. To prevent voltage loss, we recommend no more than 80w or (10) fixtures per individual run; whichever threshold you reach first.

  • Q:

    I'm planning on using this transformer (300 watts) with two 200 foot runs. Each run will have about twenty 3 watt lights on the each run. Therefore, if the load is only 120 watts, will this transformer work considering 400 total feet of wire runs? I'll be using 12 gauge wire.
    Asked on 9/12/2017 by David from CA

    1 answer

    • VOLT Lighting Specialist

      A:

      Yes; this size of transformer will work however, for runs with the lengths that you have described, we would recommend using a 10-gauge cable (rated for up to 250') as 12-gauge cable is rated for use up to 150'. NOTE: the clamp-connect style of this transformer accepts up to 12 gauge cable.

  • Q:

    Is there any reason why you could not cut the plug off and hardwire the unit to an electrical switch?
    Asked on 9/11/2017 by Jon G from Redwood City, CA

    1 answer

    • VOLT Lighting Specialist

      A:

      Yes; attempting to modify or alter the product in any manner will void the lifetime warranty. It will also void it's ETL Rating. With that being said, we would not recommend cutting the main power-cord on your VOLT® transformer.

  • 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?
    Asked on 4/18/2017 by Brian from Oregon

    1 answer

    • 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
    Mark
    Asked on 2/7/2017 by Mark from Livermore, CA

    • VOLT Lighting Specialist

      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.

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:

Excellent product. Silent operation - no transformer hum. Easy installation with removable front door. I was uncertain on the number of cables the Com tap would handle but I connected 4 and it would handle more. I selected this transformer instead of the Clamp Connect model because the Clamp Connect is larger (deeper) and wouldn't fit in my existing utility cabinet. This integrates very well with the Astronomic Timer. The timer is complex to program but the online video is great. The timer is removable so it's handy to program in the comfort of your home or office.

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.
