VOLT® Pro 900 Watt 12-22v Multi-Tap Transformer
VOLT® 12-22v landscape lighting transformers feature top-of-the-line internal and external components for professional results and commercial reliability. Truly the perfect solution for large landscape lighting systems - especially those with very long (or heavily loaded) wire runs. The increased number of voltage taps (12-22V) give the ability to compensate for voltage loss.
The extremely reliable, efficient, and quiet toroidal magnetic core lasts a lifetime. The transformer also runs cooler than conventional laminated magnetic types. The solid stainless steel body further ensures that this transformer will never corrode.
Features & Benefits:
- Stainless steel enclosure with hinged, lockable door and removable bottom panel for easy wiring.
- Cabinet Dimensions: 18" H x 10" W x 8" D
- Large ports enable 6+ cable home runs per each 300w circuit. (e.g. 6 home runs on a 300w transformer, 12 runs on a 600w, 18 runs on a 900w, 24 runs on a 1200w transformer!)
- Timer and photocell ready ports (timer and photocell not included).
- Toroid core--runs cooler, quieter, more efficient, lasts longer.
- Only draws as much electricity as needed to illuminate the bulbs you have -- e.g. a 1200w transformer will only draw 400w of power if you only have 400 watts of bulbs hooked to it. Guidelines suggest never loading the transformer to more than 80% of capacity (720 watts for this model).
- Built-in stainless steel mounting bracket.
- Includes a 5 1/2ft line voltage power supply cord. Not designed to be hardwired or for use with an extension cord, doing so will void any warranties.
- Top Mounting bracket 1 1/4" tall, 3 keyholes, bottom mounting bracket 5/8" tall, open keyhole.
- Lifetime warranty.

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:
- 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.
- 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.
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.
