Over temperature cut off. A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors – the transformer’s coils. The Actec Mini60 Electronic Transformer has the following product features: It utilises a ‘unique, patented, electronic solution’ 1 to guarantee compatibility with a range of standard 12VAC Halogen electronic transformers.

Figure 5 d High frequency kHz oscillation: 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. The load input of the wirewound transformer can be seen to be a simple 50 Hz sine wave.

Figure 4 c Redback voltage output: 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. Figure 3 a Wirewound voltage output: Figure 3 b Possum voltage output: The high frequency switching cycles are seen to stop and resume at irregular times within the Hz wave envelope.

Figure 1 a Wirewound voltage output: It oscillates about 0V, regularly switching polarity with a measured output of Figure 3 c PoweRun voltage output: This product is offered with a 5 year manufacturer’s warranty.

Both transformers specify a minimum load requirement of 0.

The transformers’ output voltage waveforms when powering a 35W Osram Halogen can be seen in the figures below. Replacing your existing 12VAC transformers in addition to your downlights can be costly and inconvenient, making it important electronif replacement LED downlights work well with your existing installation.

The yellow voltage signal is that supplied by a Redback electronic transformer to a Philips retrofit LED light. MICA Lighting, shall look after the warranty for you. 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 voltage is approximately Figure 1 i Speedy voltage output: These voltages are predominately 12volt and 24volt, but we also offer many others. Possum Electronic Transformer Power consumption: Wirewound Transformer Power consumption: The variation in the switching waveform across transformer types can be seen in figures 5b-d.

Figure 4 a Wirewound voltage output: This manifested as visible light flicker and dim light output dimmed to 0 lm after approximately 10 minutes. They differ in output and load compatibility i. Figure 5 a High frequency 37 kHz switching: In contrast, the electronic transformers output a high frequency switching signal ranging from approximately 37 kHz to 79 kHz, enveloped within a Hz waveform. The electronic transformers tested were: The primary winding for each transformer was connected to nominally VAC mains, operating at 50 Hz.
