Electronic transformers range in size from single output 60w (Class II), single output 150w
zero-load, and single output 150w (Class I). Our transformers run quiet, are instant-on, feature
fire-rated housings and dim easily with electronic low-voltage (ELV) dimmers. Generation
Lighting Electronic Transformers specify whether they have a minimum load requirement —
starting at 15w — or whether they are zero-load capable. Zero-load transformers have been
designed for the low wattage draws of LED technology. For proper operation of an electronic
transformer, the wattage load must fall within the specified range. Generation Lighting
Electronic Transformers are moisture and shock resistant, featuring soft start circuitry for
increased lamp life. Electronic transformers, as with many electronic components, may
cause radio frequency interference (RFI). Our Electronic Transformers have built-in filters to
help eliminate RFI. Should RFI be noticeable, rotate the unit to change the direction of the
electronic field or replace with a magnetic transformer, which will not cause RFI.

ELECTRONIC TRANSFORMERS
Generation Lighting laminated magnetic transformers are core and coil, isolated type
transformers. We offer several sizes of laminated magnetic transformers ranging from
75 to 300w at 12v, and 60 to 200w at 24v in either AC or DC. Each transformer features
thermal protection on the primary (120v) side. Our laminated magnetic transformers have
resettable thermal circuit breakers on the low voltage side. Other features include a faraday
shield, potted and encased core and coil for added safety and ease of installation. A boost
tap is integrated to single-tap magnetic transformers to compensate for voltage drop.
For optimum operation we recommend the load on all laminated magnetic transformers
be between 50 and 100% of the rated wattage when used with xenon and halogen light
sources. Magnetic transformers are zero load with LED lamp source. Not meeting minimum
recommend loads can overdrive luminaires and greatly reduce lamp life. Be sure to keep
insulation away from transformers. Magnetic transformers should be mounted vertically. If the
transformer must be mounted horizontally, the ambient temperature must be below 120°F
and the maximum load should be reduced to 80% of output.
MAGNETIC TRANSFORMERS
Generation Lighting systems require adequate ventilation to dissipate heat generated during
their operation. Care must be taken to avoid installing the system in confined areas where
excessive heat may result in the transformer circuit breaker tripping or causing damage to the
system and/or the area being illuminated. Surface temperatures on transformers, wiring and
luminaires must not exceed 90°C (194°F).
OPERATING TEMPERATURES
When dimming a low-voltage system, it is recommended that the dimming occur on the
primary side of the transformer, reducing the power coming into the transformer. The dimmer
must be matched to the type of transformer that's powering the system.
- For electronic transformers use an electronic low voltage (ELV) dimmer.
- For magnetic transformers use a standard, incandescent line voltage dimmer or a magnetic
low voltage (MLV) dimmer.
