Constant impedance means that if the voltage decreases the current will descrease with the same ratio also and then the power at the square of the voltage. Constant voltage drivers are similar, but opposite, with fixed voltages and variable currents.

A cc power source will maintain current at a relatively constant level, regardless of fairly large changes in voltage, while a cv power source will maintain voltage at a relatively constant level, regardless of fairly large changes in current. Many of b&k precisions 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.

When battery charges at 500ma constant current, voltage rises up to 12v, and then power supply gets limited to 12v. A constant impedance load is simply a load that presents an unchanging impedance, like a resistor.

A Constant Impedance Load Is Simply A Load That Presents An Unchanging Impedance, Like A Resistor.

In general, power supply often means a voltage source, but there are also current sources that supply current. Some people say that in the volt ampere characteristics of led, the voltage is fixed and the cur A power supply is a device that supplies electrical energy to a load, and there are two types:

A Cr Load Would Demand Zero Current At Start Up.

Constant current driver constant voltage driver; Voltage sources and current sources. If current is not regulated, led brightness can fluctuate shortening the lifespan.

Lacking That, Constant Current If The Strip Is Always The Same Area And Constant Voltage If Not.

In constant voltage mode, a power supply behaves like a voltage source, holding the voltage across the output terminals constant while the current output varies. A power supply capable of outputting a constant voltage to the load. The ideal power supply is actually constant current density.

Led Luminaires And Their Drivers May Be Either Constant Current Or Constant Voltage.

The term "constant" is relative. A constant power load varies its impedance on change of input voltage to keep the power constant. These factors tie into the types of power supplies used to drive the leds.
