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...

What kind of the dimmer for dimmable led driver?

Dimmer switches are a great way to control the lightness in a room, you are able to change the brightness throughout the day without changing the bulb, because dimmers will work by reducing the electrical current or voltage. While you decrease the brightness, you save energy and also increase the life span of the led light. You can see dimmer switches work with many common led light fixtures. Our ...

What is TC point？

In daily experience, some electricians will ask the sales of Smarts led power supply before installation, what is the position of the TC point on the power supply? Are they fixed for each series of the led driver? Actually, it means the TC temperature of the power supply is the surface temperature of UL listed power supply directly above the transformer when the power supply rises to a stable leve...
