LED Drivers have become increasingly popular over the last few years as they offer an efficient, cost effective and energy saving lighting solution. The PWM-120-12 is a LED driver that has been designed and engineered specifically for use with light emitting diodes (LEDs). The PWM-120-12 features a power factor corrected (PFC) switch mode power supply (SMPS) and is designed to provide extremely stable operation even under varying input voltage and load conditions.The PWM-120-12 LED driver is designed primarily as an outdoor lighting power source, and is ideal for use in applications such as parking lighting, wall washing, and decorative lighting. The driver can also be used indoors in applications such as architectural lighting, show lighting, and entertainment lighting. Additionally, the PWM-120-12 can be used in applications that require constant voltage output with pulsed width modulation (PWM) control.The PWM-120-12 utilizes two power supplies, one for the main DC LED supply and the other for the PWM control circuit. The driver’s input voltage is connected to the main supply, and is then regulated to provide a Constant Voltage output. The voltage is regulated using a feedback loop that compares the input voltage to the output voltage, and adjusts the duty cycle of the power supply accordingly. The power converter then steps this down voltage to the LED output and provides a constant current source for the LEDs.The PWM control circuit, which is connected to the second power supply, then adds the PWM signal to the main DC supply. This PWM control signal is fed back to the power converter and adjusts the output according to the PWM width. The PWM signal can be used to dim the output or adjust the colour temperature, depending on the application.The PWM-120-12 LED driver is designed to provide reliable and efficient operation even over long lengths of time. It also features over-voltage, over-temperature, and short-circuit protection to ensure safe operation.In addition to the multiple protection functions, the PWM-120-12 also features power factor correction technology (PFC). PFC enables the driver to maximize power factor and reduce harsh electrical noise, resulting in longer life, improved efficiency, and reduced electrical bills.Overall, the PWM-120-12 LED driver is an ideal choice for applications requiring high efficiency, reliable operation, and a wide range of dimming and colour temperature control options. With the added benefit of power factor correction, the PWM-120-12 is the ideal power source for high-power LED designs.
