Phasecut: LED-Drivers Constant Voltage (CV)

Leading-edge and trailing-edge dimmers, for example TRIAC dimmers, are commonly installed in conjunction with traditional incandescent lamps. Their operating principle is fairly simple. 50 Hz 230V mains voltage is delivered as alternating current (AC) and thus changes polarity 50 times per second. Each polarity change consists of two sinus half-waves. TRIAC dimmers and other phase cutting dimmers utilize this characteristic for power limiting. Each half-wave is cut short – either its beginning (leading edge) or at its end (trailing edge). Variation of the cutting range changes the transmitted power and thus the brightness of the incandescent lamp. Of course, today, LED lighting is a vastly superior choice to traditional luminaires due to markedly improved energy efficiency and longevity. To be able to continue to use existing phase-cut dimmers with LEDs, the right type of LED power supply – a Phase-Cut LED Driver – is required. ProConnecting offers an extensive choice of HuaTec, SC Power and Snappy Phase Cutting LED Power Supplies. Constant Voltage (CV) Phasecut LED Drivers are a reliable and cost-effective choice for most commonly sold LED illuminants with integrated current-limiting resistors, such as LED strips.
