PDA012A-350C-H-R

LED drivers are the power supply devices used in LED lighting applications and are responsible for delivering the precise voltage and current to a LED or array of LEDs. In this article, we will discuss the application field and working principle of PDA012A-350C-H-R LED driver.

Application Field

The PDA012A-350C-H-R is a 350 watt LED driver which is mainly used for commercial lighting applications. This driver is widely used in street lights, flood lights, spot lights, high bay lighting, parking garage lighting, security lights, landscape lighting, and decorative lighting. The driver is specifically designed to accept AC line voltages up to 347V and has an adjustable operating voltage of 12 to 43V. This LED driver has a high power factor of 0.9 with a maximum efficiency of 88%.

Working Principle

The PDA012A-350C-H-R LED driver is based on the principle of constant current output voltage regulation. It is a type of switching power supply which converts the input voltage from the AC mains to a DC voltage compatible with the LED lighting devices. The input voltage is first stepped down using a transformer and then rectified into a DC voltage. This DC voltage is then converted to a linear DC voltage by a switching converter, which is regulated by a closed-loop control circuit. The output voltage is then adjusted to the desired level using the adjustable voltage control.

The driver is also equipped with a number of protection features like over-voltage, over-temperature, over-load and short-circuit protection. The PDA012A-350C-H-R also has a wide operating temperature range of -40oC and +85oC. It is also CE and UL listed for safety and reliability.

Conclusion

In conclusion, the PDA012A-350C-H-R is an ideal LED driver for most commercial lighting applications. It is a highly efficient LED driver, with a wide voltage range and a number of safety and protection features to ensure optimal performance. The driver is also highly reliable and is CE and UL listed for safety.
