Constant voltage constant frequency power supply.

Should the constant voltage power supply exceed 5a the rated current then the power supply will go into an overload protection mode operating from 105 150 of the rated output power. This initiated the development of the linear regulator series shunt circuits. Still the efficiency of this system is poor. Many of b amp k precision s dc power supplies are categorized as this type of power supply and depending on the application it is important and useful to know how to switch between the two modes.

Most often constant voltage drivers are implemented in under cabinet lights and other led flex strip applications but it is not limited to those categories. Products with these current regulating devices might require a constant voltage power supply if they need a different operating voltage than what s supplied by the power source home vehicle etc. But they suffer from changes in the input or at load. The constant voltage source provides a constant voltage to the load regardless of variations or changes in the load resistance.

An example of a constant voltage power supply is below in the mean well lpv 60 12. Provides a wide variety of constant current sources constant voltage sources solutions for military organizations such as nasa navy and the boeing company. This article primarily applies to dc power supplies that can switch between constant voltage cv and constant current cc mode automatically. Mean well designed their pwm series dimmable ac dc class 2 power supply to be ideal for led strip lighting applications.

The lpv 60 12 will maintain a constant 12vdc if the current stays below the 5 amp maximum shown in the table. Simple dc power supplies can be made with rectifiers. Provides single phase and three phase 400 hz output frequency converters to aerospace industries to simulate the power on aircrafts. Featured is a constant voltage output pwm mode 1 47khz electrically engineered to keep your led strip color and brightness consistent.

Constant voltage power supplies can be used to power led products that have resistors or constant current drivers.
