The voltage is approximately The LED failed to turn on when supplied using the Possum or speedy electronic transformers. Despite the differences in the voltage waveform, all five transformers successfully powered the 35W Halogen light with no perceptible flicker or obvious difference in light output. Their specified load requirements were 0. All items warranty are covered by MICA Lighting, therefore should you have any trouble with your item, you only need to contact us. Figure 2 c PoweRun voltage output: Magnetic transformers will generally work with all MR16 LED lights, albeit at the cost of efficiency and extra power consumption as was explored in this FAQ article.

The power losses as a direct consequence of increased switching frequency can therefore be viewed as negligible.
Figure 2 b Possum voltage output: Figure 1 g Redback voltage output: Brand new in manufacturer’s packaging. This product is offered with a 5 year manufacturer’s warranty.
The LED failed to turn on when supplied using the Possum or speedy electronic transformers. Redback Electronic Transformer Power consumption: Electornic Actec Mini60 Electronic Transformer is commonly used for the standard 12v low voltage halogen downlight.

The variation in the switching waveform across transformer types can be seen in figures 5b-d. All items warranty are covered by MICA Lighting, therefore should you actrc any trouble with your item, you only need to contact us.
Their specified load requirements were 0. Figure 5 a High frequency 37 kHz switching: Sign up for our newsletter:.
LEDBenchmark – 12V Transformers and LED Compatibility
Some LED lights, such as the DR by Brightgreen and the 10W Philips Master, have additional modules that intentionally alter the load seen by the transformer to better replicate the load characteristics of 12VAC halogens and thus ensure broader but not necessarily universal compatibility with electronic transformers.
The difference in their voltage outputs can be seen in figure 6. Figure 1 a Wirewound voltage output: It utilises a ‘unique, patented, electronic solution’ 1 to guarantee compatibility with a range of standard 12VAC Halogen electronic sctec. Electronic 12VAC halogen transformers can vary significantly in design and consequently in how they respond or do not respond to different loads.
The load input of the wirewound transformer can be seen to be a simple 50 Hz sine wave. Elecrronic 2 c PoweRun voltage output: The yellow voltage signal is that supplied by a Redback electronic transformer to a Philips retrofit LED light.

The voltage is approximately Close-ups of the switching waveforms generated by different transformers is provided in the following figures. Figure 2 e Speedy voltage output: Figure 1 i Speedy voltage output: Figure 1 c Possum voltage output: Figure 1 e PoweRun voltage output: These voltages are predominately 12volt and 24volt, but we also offer many others.
An Atco TM wire wound transformer was used for comparison. The high frequency switching cycles are seen to stop and resume at irregular times le the Hz wave envelope. Figure 2 a Wirewound voltage output: Both transformers specify a minimum load requirement of 0. Based on the voltage outputs of these transformers taken above, they are likely to have very similar internals and consequently similar responses to identical loads.
