AMP® 100 Watt Slim Line LED Transformer | Low Voltage Landscape Lighting

This low-profile transformer breaks ground in simplicity of installation and control.

The clamp-type terminal blocks are impressively easy to use - taking seconds to connect - compared to the time for standard terminal blocks. Just insert the stripped wire and close the clamp!

Additionally available (sold separately) is the AMP® 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 to replace the metal knock-outs of traditional transformers. Traditional knock-outs required tools and were difficult to remove. The grommets on the new Slim Line Transformers are removed easily and can be replaced if necessary.

To make the transformer slimmer, lighter, and simpler-to-install, we eliminated unnecessary voltage taps. Instead, the single 15V tap replaces having to choose among 12V, 13V, and 14V. The Slim Line Transformer is all you need for any small to medium sized (up to 100W) AMP® LED system with no 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 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.
  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.

International Shipping***

We require $1,000 USD order minimum (before shipping charges) on first time orders and a $500 USD order minimum (before shipping charges) on all future orders with an established account.

The recipient of an international shipment is responsible for any import taxes, duties, and any additional fees levied by the destination country. We have no control over these charges and cannot predict what they may be. Customs policies vary widely from country to country. Contact your local customs office for further information. When custom clearance procedures are required it can cause further delays in shipment. Due to high shipping costs/duties. International customers are responsible for shipping on warrantied replacements, returns, and/or exchanges.

***International rules apply to Canada. For all orders being shipped outside the U.S. and Canada, the customer must place the order by phone (not online); these orders require payment by wire transfer. Other rules may apply.
