All of the QT toroidal transformers come standard with multiple taps allowing the installer to compensate for voltage drop, a normal occurrence in any low voltage lighting system. The QT offers 5 taps, 11-15 or 22-30 volts. 100% light output is achieved at 12V. Most transformers only provide 11.4V with additional losses incurred through the dimmer and over the voltage drop on the wire, resulting in 10Volts to the lamp. 10 Volts only allows the lamp 50% light output, Q-Tran’s multiple taps allow the installer to boost up the voltage, providing between 11.4-12 volts to the lamps, or between 85-100% light.
All of the Q-Tran toroidal transformers are built in Q-Tran's factory in Milford, Connecticut. This allows us to control the quality of materials, designs, equipment, and testing. Every single transformer is tested three times before it leaves our facility. The materials that we use and the equipment that we have to manufacture the transformers allow us to make the quietest transformer available in the lighting industry. We have an anechoic chamber in our R&D lab allowing us to benchmark the noise levels of the different size toroids and continually improve upon them. Acoustical engineers define quiet as being between 25-30dB. Standard transformers operate over 40dB when dimmed, Q-Tran’s transformers operate around 23 when dimmed, lower than the bottom threshold parameters that acoustical engineers have defined.
Q-Tran includes three safety devices: primary circuit protection, thermal auto-resettable breaker built into the toroid to prevent overloading conditions, and secondary circuit protection, providing the safest power supplies on the market.
The QT product line is our flagship product offering of the indoor transformer series. The QT enclosure is UL listed to be either surface mounted or recess mounted into a 2X4” stud wall and is listed as an inherently protected, IC rated fixture allowing all QT units to be recessed into a wall in direct contact with insulation and a zero clearance to combustible clothing. The average efficiency of the QT product is over 95%, providing for a very cool operating temperature and allowing Q-Tran to have this very unique UL listing. All QT units come with universal mounting brackets (UMB), allowing the installer to either surface mount the enclosure, recess it into a wall with differing thickness drywall or to suspension rod mount the product for above-ceiling or open-ceiling conditions. All QT units come standard with 3 safety devices built into the unit (a requirement by UL2108 and NEC 411).
The capacity of the QT product ranges from 50 Watt transformers up to a 1500 Watt unit. All of the Q-Tran transformers can be fully loaded. You do NOT need to de-rate our product lines! In addition to our single transformer offering, we also have the ability to have multiple transformers inside of one enclosure allowing the consolidation of transformer requirements into fewer enclosures, saving on for installation cost and material savings.
