Since we started sharing knowledge about dimmable power supplies, we have frequently received various topic suggestions from our audience. Recently, while reviewing the comments, one question caught our attention: "What is a constant power output dimmable power supply?" In this article, we will explore what —— constant power output dimmable power supply is and how it plays a crucial role in practical applications.

What is a constant power output dimming power supply?

Constant power output dimming power supply can automatically adjust the output current according to the change of lamp voltage, so that the total power remains constant.

According to the power formula P = V * I, it is known that voltage V and current I are inversely proportional. Therefore, when the output voltage V drops, the constant power output dimming power supply will increase the output current I; when the output voltage V rises, the constant power output dimming power supply will decrease the output current I to maintain a constant total power.

Take a constant power drive power supply with a power of 40W as an example

What are the application advantages of constant power output dimming power supply?

Constant power output dimming power supply is adaptable: the constant power output dimming power supply can automatically adjust the output current when the output voltage changes, to ensure the constant output power, which also enables the dimming power supply to maintain stable operation under different working conditions.

Constant power output dimming power supply can achieve high efficiency utilization: no matter in high voltage or low voltage, constant power output dimming power supply can keep the output power constant, avoid power waste caused by voltage mismatch, and improve energy utilization.

Application of constant power output dimming power supply can prolong the service life of lighting equipment: constant power output dimming power supply can avoid damage to lighting equipment due to excessive current through automatic current adjustment, and reduce the possibility of performance degradation caused by insufficient current, which is helpful to extend the service life of lighting equipment.

Constant power output dimming power supply has flexibility and compatibility: to meet the dimming requirements of different types of LED lamps at different working voltages.
