VOLTPro 600 Watt 12-22v Multi-Tap Transformer

Magnetic vs Electronic Transformers

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 Types. There are two types of magnetic landscape lighting transformers. These vary by the type of core: laminated/stacked cores (also know as EI type) or toroidal cores. 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. Toroidal cores 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 the less expensive EI core.

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.

Don't forget to order a timer or photocell for automatic operation of your VOLT® transfomers.

Operating Temperatures:

The VOLT¸® Toroidal Core Transformers run 10-20C cooler than laminated magnetic core transformers. They are more efficient, use less energy, last longer, and are more reliable. They are also approved for mounting indoors as well. Below is the normal operating temperatures of our transformers:

The VOLT® transformers are manufactured with thermal protection on the primary, they will automcatically shut down when over-heated.

Transformer Instructions

Quick Start General:

  1. The transformer plugs into an exterior GFI outlet. Do not use extension cords with transformers.
  2. Each 300w circuit has its own circuit breaker (toggle switch) and Common (Black label that says COM). E.g. a 300w transformer has 1 COMMON TERMINAL, 600w transformers have 2 COMMON TERMINALS, 900w transformers have 3 COMMON TERMINALS, a 1200w transformer has 4 300w COMMON TERMINALS.
  3. Use COMMON TERMINAL #1 until you begin to approach 300 watts of lamps used (for example when you reach 250-275 watts), then start using COMMON #2, and so on.
  4. This 75W transformer is suitable for outdoor use only.

Connecting Home Runs to the transformer:

  1. The home run cable (e.g. 10/2 or 12/2) has two wires. One wire gets connected to the COMMON TERMINAL (black label that says COM), the other wire connects to a VOLTAGE TERMINAL (the colored labels that say 12, 13,14, etc). Which VOLTAGE TERMINAL you connect that particular wire on depends on the voltage you need for that run. This is a MULTI-TAP transformer, which means you can output at a variety of voltages to compensate for VOLT DROP (see our learning area for more information on layouts and voltage drop). For example, if you have a long run of 100 feet you may need to use the 15v VOLTAGE TERMINAL in order to have 12v of power all the way out at the far away fixtures.
  2. You can hook up multiple home runs to each and any of the terminals. For example you may have 6 home runs, in which case you would have 6 wires in the same COM terminal and the other half of the 10-2 wires go into the colored terminals. The VOLTAGE TERMINALS can have multiple runs/wires in each tap as well.
  3. To connect a home run wire to the terminals, split the 10-2 or 12-2 wire down the middle to separate the two wires and strip half an inch of insulation off each wire. One end goes in the COM terminal, the other into a voltage terminal. Loosen the terminal screws (small flat head screw driver) and insert the wire into the terminal opening which is located at the bottom (90 degrees from the terminal screw facing the bottom of the transformer). Tighten screw to secure wire(s).


  1. Low voltage wire does not have polarity, it does not matter which of the 2 wire connects to the COMMON TERMINAL and which to the VOLTAGE TERMINAL, as long as one wire goes to each.
  2. Optional timers and photocells plug right into the transformer ports labeled and located inside the cabinet.
  3. It is easier to see and insert the wires into their terminals when the transformer is lying on the ground. Affix all your wires BEFORE mounting the transformer.

VOLT Outdoor Lighting Transformer Troubleshooting


  1. First check that there is power at the GFI outlet. Do not assume there is power. Check it with a Voltmeter and make sure there is ~120v AC.
  2. If you have a timer please unplug/remove it. They are often a source of failure. Test the Timer Outlet inside the transformer cabinet with a Voltmeter. You should have 120v AC there as well. If you do, go ahead and plug the timer receptacle cord back into the timer receptacle outlet (the short cord inside the transformer cabinet needs to be plugged into the socket inside the cabinet) to complete the circuit or the transformer will not operate.
  3. If you have a photocell installed, please remove it. Then put the jumper cable back into the photocell receptacle port to complete the circuit or the transformer will not operate. Be sure the jumper is pushed down tight. If you have a photocell in the transformer will not turn on when it is light out. Even if you cover up the photocell there is a delay (the photocell needs to be covered for about 1 minute before it will allow the transformer to turn on).
  4. Make sure all the toggle switches are in the “ON” position (UP). The toggle switches are circuit breakers and can trip if there is a surge, overload or short. Sometimes the circuit breakers themselves can fail.
  5. Now it’s time to test the secondary side (low voltage taps/ mutitap). Do not use the screws facing forward to test for voltage, put a voltmeter in the “garage door style opening” that hold the cable (on the underneath side of the outdoor transformer). Put one voltmeter prong on the common, the other on a tap (eg 12v tap or 15v tap). You should read anywhere from 12v AC to 22V AC depending on which tap you are testing. If you do not get any voltage, remove any wires (home run wires) from the common and the taps you are testing and try again without any load.

If you are not getting voltage at any of these points:

  1. The Timer Receptacle Outlet
  2. The Secondary Side (low voltage Taps/Commons)

Great Transformer February 25, 2014
Reviewer: Scott from San Diego CA  
Replaced 2 300W Malibu transformers that lasted less than 3 years with this unit and the digital timer.  Easy to setup and the voltage taps give me brighter and more consistent lighting throughout my two line system.   Should have bought the transformer from Volt when I purchased all my lights from them.  The slight cost difference would have been worth it.

Truly a professional grade product October 3, 2013
Reviewer: Rob from Yuba City CA  
I purchased one of the 600 Watt transformers in May of 2011.  That was 2 years and 4 months ago.  Every single day of that time period it has operated perfectly turning my 52 yard lights on at dusk and off at 10:30 PM.  I tried the ones available through Lowe's and Home Depot and they just didn't last.  This one cost more but I'm very pleased with the performance.  It is very reliable.

Amazing performance but one flaw June 21, 2013
Reviewer: Rob from Chadds Ford PA  
This has been amazing i have about 20 lights hooked up to this all different distances and it works great! The only thing i don't like is that I wish the COM ports were bigger and that if you order the photocell they already pop the hole out for you because thats kindof hard and i end of bending a scratching the stainless steel. There also should be a PVC pipe port so you can hide the wires...
