Phantom Low Voltage Lighting Transformers

To figure total requirements for Phantom Lighting transformers, calculate total watts per foot divided by voltage equals total amperage. (watts / voltage = amperage). Refer to the table to calculate wire size and fusing requirements or see transformer page for more specific details.

SECONDARY WIRING DIAGRAMS

SECONDARY WIRING EXAMPLES

Just because you are installing a low voltage lighting system, it doesn’t mean that you can use low voltage wire! In fact, low voltage current operates at higher amperage levels than standard 120 volt systems. The current is 10 times greater for a 12 volt system than for a 120 volt system of the same wattage. Consequently, you must use larger wire sizes for 12 and 24 volt systems to minimize voltage drop and to handle the amperage loads. It is always best to locate your transformer adjacent to the lights, in the center of the run or as short a distance as possible to maintain lumen output. When at all possible, voltage drop should be limited to 5% loss between the transformer and the lighting strips.

TERMS & CONDITIONS

To comply with Phantom Lighting System warranty policies and ETL Standards, all lighting strips must be used in conjunction with Phantom lighting transformers. All Phantom lighting transformers are ETL Approved for Class 1 applications and are strongly recommended for proper operation of lighting strips. Phantom transformers should not be located in areas with no ventilation or subject to high ambient temperatures. If ambient temperatures exceed 115°F (46°C) around the transformer the circuit breakers may nuisance-trip due to excessive heat. CAUTION: FAILURE TO CORRECTLY SIZE PRIMARY AND SECONDARY CONDUCTORS AND OR OVERLOAD PROTECTION MAY RESULT IN BODILY INJURY OR SERIOUS PROPERTY DAMAGE.

Likewise, Phantom lighting strips should be installed in such a way as to properly dissipate heat. We recommend that you allow a minimum overall 3” set back from the wall or ceiling plane being illuminated in a cove lighting application. Not only does this clearance allow the heat to escape, but it allows room for installation, servicing and changing incandescent, xenon and LED lamps. If you are using exotic wood, veneers or heat sensitive fabrics we suggest increasing this clearance from a 3” to 5” set back.

Request design assistance for Phantom cabinet lighting, display lights, task lighting or cove lighting products.

If you have any questions or concerns regarding your application, please contact a factory customer service agent, a lighting sales representative, a licensed electrician or consult the National Electric Code.
