Rev. 08/8/18 1 of 4 Project: Fixture Type: Location: Contact/Phone: Low Voltage Systems 12V AC REMOTE MOUNT MAGNETIC TRANSFORMERS MAGXFMR D3.1.3 PRODUCT DESCRIPTION 12VAC Remote Mount Magnetic Transformers are designed to be installed in remote locations such as basements, attics, plenums and electrical closets. The location must be accessible and well ventilated with ambient temperatures below 140˚F. They are available with maximum wattage ratings of up to 600W and are available in 1-circuit and 2-circuit configurations, enabling two separate feeds to be made from the same transformer. These transformers are deigned for either 120-volt or 277-volt input, and have premium resettable magnetic circuit breakers, dual-tap standard/boost tap primary input leads to adjust for voltage drop and may be dimmed using dimmers qualified by Juno. Transformers may be used to operate 12VAC LED or incandescent loads. PRODUCT SPECIFICATIONS Electrical 120VAC or 277VAC input • 12V AC output • May be used to operate LED or incandscent loads.

Rev. 08/8/18 2 of 4 D3.1.3 Low Voltage Systems 12V AC REMOTE MOUNT MAGNETIC TRANSFORMERS MAGXFMR APPLICATION Consideration • Trac run length 12V Magnetic Transformer • Use for medium to long run lengths and medium to high wattage systems 12V Electronic Driver/Transformer • Use for short to medium run lengths and low to medium wattage systems • Dimming • For optimal results, use dimmers specifically designed for use with magnetic transformers; transformers used with Juno LED fixtures should only be operated with dimmers pre- qualified for suitability by Juno Engineering • For optimal results, use dimmers specifically designed for use with electronic transformers; transformers used with Juno LED fixtures should only be operated with dimmers pre-qualified for suitability by Juno Engineering • Transformer Location • Install in well ventilated locations where ambient temperature will not exceed 140°F (60°C); transformers must be accessible • Install surface mount units in well-ventilated location where ambient temperature will not exceed 120°F (50°C) Voltage drop is a function of the following factors: Wire Length: As the wire length from the supply to the fixture becomes longer, voltage drop increases. Wire Diameter: As the wire cross-sectional area becomes smaller, voltage drop increases (this is related to the resistance per foot of wire). Amperage of the Electrical Load: As the amperage of the electrical load increases, voltage drop also increases. Voltage drop in 12 volt systems is 10 times greater than in 120 volt systems. This is because a load of the same wattage has 10 times greater amperage in 12 volts as compared to 120 volts. This is illustrated by the formula: WATTS = VOLTS x AMPS Assuming a 120 watt electrical load: 120 WATTS = 12 VOLTS x 10 AMPS 120 WATTS = 120 VOLTS x 1 AMP Voltage drop from a magnetic transformer to the first lampholder on 12V Trac 12 can be calculated as follows: TRANSFORMER D A VOLTAGE DROP = 2D x A x Ω WHERE: D = Distance in feet from transformer to 1st lamp A = Total amperage load of all lampholders on the trac Ω = Resistance per foot of wire per the following chart: Wire Gauge Resistance Per Foot of Wire (OHMS) #8 .00065 #10 .00104 #12 .00166 (A = ______ = ______ )WATTS WATTS VOLTS 12 VOLTAGE DROP CALCULATIONS (FOR MAGNETIC TRANSFORMERS) 1300 S.
