EmbSoft Technologies presents a very efficient Static Variac powered by ARM Cortex-M0 MCU. This product is built on a concept called “Sine Wave Dimming”.
Our Product converts input power of AC Mains(230V) into a sine wave with a reduced voltage. Static variac provides uninterrupted reduced sine wave voltage. This product accomplishes this by converting the incoming AC supply through Pulse Width Modulation (PWM) to the desiredvoltage.
Pulse Width Modulation switches the power at an extremely high frequency. The duration or duty cycle which can be configured through the HMI decides the Output Voltage. The high- frequency switching signal is then filtered into a new sine wave with the desired magnitude and no interruptions.
Applications:
Static Variac is mainly used for high-end dimming of directly powered or transformer fed lighting loads. Because the power is not being switched on and off, Static Variac is electrically and acoustically very quiet.
