VOLT® 300 Watt Slim Line LED Transformer for Low Voltage Landscape Lighting

This low-profile transformer breaks ground in the simplicity of installation and control. The clamp-connect terminal blocks are impressively easy and safe to use - taking seconds to connect compared to standard terminal blocks. Just insert the pre-stripped wire and close the clamp!

Also available (sold separately) is the VOLT® newly designed timer/photocell combination. When installed, it is visible through the housing window and can be set for simple dusk-to-dawn operation, or set to turn off after a certain number of hours. Photocell sensitivity may limit transformer placement. This timer is a removable module - easily replaced.

The Slim Line Transformers have an easily removable, tool-less grommet that replaces the difficult to remove metal knock-outs of traditional transformers. The grommets on the new Slim Line Transformers are removed and replaced easily if necessary.

To make this transformer slimmer, lighter, and simpler-to-install, we eliminated unnecessary voltage taps. With the new Slim Line Transformer, there is no need to worry about voltage loss.

For Your Information: Transformer Technology

Magnetic Transformers. There are two types. These vary by the type of core:

  1. Laminated/stacked cores (also known 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.

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.
