How many LED strips can you connect?

Electrically speaking, every 5 meters must be connected in parallel, but physically speaking, they can be arranged from beginning to end until about 20m (it may cause a voltage drop and cause the brightness of the lamp to dim). For example, if you want the led power supply waterproof to drive your 15m LED strip. You can do: Firstly, you could connect 10m wires to the led power supply waterproof. S...

What is voltage drop?

When using a high efficiency led driver to drive multiple lights in a house, we often encounter a voltage drop, so what is the voltage drop? Voltage drop is the decrease in voltage when current flows through various components of the circuit. If we connect the wires from the local e-commerce to the home. Under ideal conditions, current flows unimpeded along the wire until it reaches our house. The...

What is difference between constant current and constant voltage?

1. Constant current: no matter how the load changes, the output current remains unchanged. If the ammeter is connected to the load in series and the voltmeter is connected in parallel, it will be found that the larger the internal resistance of the load is, the higher the output voltage is, and the ammeter indication remains unchanged. 2. Constant voltage: it is what we often call regula...
