Switch Mode Power Supply (SMPS) Transformers

WE-FLEX Transformers 3x2 windings Isolation voltage 500Vdc Low stray inductance Operating temperature: -40°C to +125°C Applications include: flyback, forward, push-pull, step-down, step-up, SEPIC converters Note Power levels of between 1 and 50 Watts can be transformed with the WE-FLEX series transformers. They can be used at switching frequencies of up to 1 MHz.

Electronic Converter for MR16 Independent converter. IP40, class II double insulation for controlling high-power LEDs. For controlling 1 to 10 type MR16 LEDs. Protection with automatic recovery against overheating, open circuits, short circuit on secondary. Stabilised output: 24 V, 20 W. Wide range of supply voltage: 100 → 265 Vac. Caution Not suitable for use with a dimmer. Low Voltage Lighting Transformers Dimming Methods (where applicable): Leading Edge: The control device is either a thyristor or triac which blocks power until they are switched on by the control signal. At that point the current flows almost instantaneously and continues to flow until the end of the half cycle of the mains waveform. When the signal reaches zero, the device turns off and no more current is passed until it is triggered again. Turning the power on and off in this manner averages out creating a constant intensity level and by altering the precise trigger point over a period of time the lamp can be dimmed. Trailing Edge: Since this method of dimming uses transistor technology it is not limited to just switching, therefore current can be controlled gradually. Transistors can be programmed to pass current at the start of each half cycle, and gradually switch off later. This will control the full amount of power reaching the lamp without the side effects of a step increase in current.
