VOLT 900 Watt 12-15v Multi-Tap Transformer

Magnetic Transformers vs Electronic Transformers

Magnetic 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 (110 v or 120 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 fewer windings, it has a low voltage. The size of the secondary coil or windings determines the voltage output of the transformer.

With-in magnetic transformers there are two types of coils or windings: laminated/stacked cores 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, don't buzz and rattle, run cooler but are more expensive to make.

In either case, toroidal or laminated cores, magnetic transformers use a lot of copper windings, are very heavy and expensive. However they are the much more reliable, quieter and the only real solution for an outdoor lighting solution.

Electronic Transformers use an inverter to change the frequency of the electricity form 50 Hz to about 20,000 Hz. By not using bulky and heavy copper windings, electronic transformers can be very small, light and inexpensive. As such they can even be incorporated into the lighting fixtures themselves. All transformers that are small, light or built into a fixture are electronic. The downside is they have short life spans and can be noisy. For example you are probably familiar with the florescent light that takes a long time to come on or that florescent fixture that has failed-- that is usually the result of the electronic transformer in the ballast failing-- a very common occurrence. Additionally they cannot take as high loads and their performance is effected by heat. They hotter the operate or their operating environment, the shorter their life span. Electronic transformers will not perform well in hot environments.

In short magnetic and electronic transformers use two different technologies to lower the voltage-- one is inexpensive but unreliable, the other is heavy duty but bulkier and more expensive.

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.

    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).

    Other:

    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

    5 EASY STEPS

    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:

    a. The Timer Receptacle Outlet

    b.The Secondary Side (low voltage Taps/Commons).
