VOLT® 75 Watt 12 & 15v Multi-Tap Transformer

Download the Transformer Quick Start Guide PDF

VOLT® 75W Landscape Lighting Transformers feature top-of-line internal and external components for professional results and commercial reliability. Truly, the perfect solution for a small landscape lighting system. This extremely reliable, energy-efficient, and quiet transformer will last a lifetime. The stainless steel body deters rust and maintains integrity even in corrosive outdoor environments.

The 12- and 15-volt taps give you choices for fixtures that are either far or near the transformer; or for wire runs that have heavy loads. Convenient stainless steel mounting bracket, removable door, and removable lower plate make installation an easy process.

Built-in mechanical timer allows for easy system programming. Photocell receptacle allows your transformer to be fully programmed to daylight scheduling.

Since wiring can be difficult on a transformer with a very small body cavity, our VOLT® 75W Multi-Tap Transformer features approximately 35% larger openings than other similar models. That allows you to organize your incoming lines and make connections without hassle.

Easily one of the best low voltage transformers on the market. Don't settle on any lesser quality! Order your commercial-grade low voltage transformer today from VOLT®.

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/ multi-tap). 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)

Very Well Made May 16, 2016
Reviewer: Stephen Jones from Street, MD United States  
This is a very well made transformer. Nice stainless steel enclosure and easy to wire. I see complaints about the KOs being hard to get out. This wasn't a big deal to me as I am an electrician and used to it. If you hit the knockout very sharply and hard on the edge it will start to pop right out. No complaints. Great product.

It Works Great April 1, 2016
Reviewer: Naptown from Annapolis, MD United States  
Installed this transformer for 7 LED fixtures (also bought here) and it works flawlessly.  I read the reviews about the knockouts so I removed the whole bottom plate from transformer then braced it before using the screw drive to punch it out.  It came out cleanly with first hit.  The inclusion of integrated timer saves money as well.  The directions were confusing so just in case for the timer here is how it works.  When the trippers are located towards the center, that is the ON position.  Move all the trippers away from the center for the time range you want the lights to be OFF. Hope it saves some Youtube searches!

All in one December 29, 2015
Reviewer: Derrick Kelly from Pembroke Pines, FL United States  
Small, but does the job for not more than four lights. Love the built in timer, all of them should be that way.
