What is constant voltage power supplies?
Constant voltage mode which is sometimes referred to as voltage-controlled mode, a power supply behaves like a voltage source, holding the voltage across the output terminals constant while the current output varies, depending on load conditions.
What is constant voltage and constant current?
Constant voltage luminaires require a steady voltage to be supplied from the driver eg 12 or 24 Volts. For these lights the voltage is fixed by the driver but the current may vary. … Constant current luminaires require a constant current to be supplied from the driver eg 350mA or 700mA (milli-amps).
How to choose a power supply for your LED strip project?
- Step 1: Determine the LED strip voltage. The first step is to figure out what the voltage of the LED strip is. …
- Step 2: Determine the power draw of the LED strip. Next, look for either a wattage (W) or amperage (A) specification for the LED strips.
- Need to know where is the end systems suchs indoor or out door.
- Step 3: Determine the connection method.
