The importance of understand LED characteristics for 24v led driver application?

There was a customer who required the input power of the lamp to be a fixed value with a fixed error of 5%, and the output current could only be adjusted for each lamp to reach the specified power. Due to different working environment temperatures and different lighting times, the power of each lamp will still vary greatly. The customer puts forward such a request, although it has its marketing an...

What is difference between 180-265vac input and 100-277vac input led driver?

The difference between a wide input 100-277vac led power supply and an 180-265vac led power supply is: the voltage output range is different, the adaptability to the power source is different, and the lack of power is different. The voltage output range is different 1. Wide power supply: The wide power supply voltage output range is generally in the standard of 85～265VAC. 2. Ordinary power supply:...

What is the difference between PWM dimming system and a 0-10V dimmer?

PWM dimming system (Pulse Width Modulation System Module) is a control system. This kind of PWM (Pulse Width Modulation) system can be connected to a computer for control, but the dimming can be achieved directly through the PWM system in most cases, no need to connect to a computer. The PWM dimming system can control multiple lines of dimming, and can load thousands (million) wattages of 0-...

What do you think of TRIAC dimmable led driver in your daily life?

There is no doubt that TRIAC dimming led driver is the most widely used in practical applications. The dimming used in traditional lighting is basically Triac. In addition, for decades, electricians have used traditional methods for the circuit wiring of floors and houses, and they have not considered leaving a few more control lines. Therefore, lighting comes in only after the water and electrici...

What is LED driver used for?

UL LED drive power supply is the key to LED lamps. It is like a person's heart. To manufacture high-quality LED lamps for lighting, you must abandon constant voltage LEDs. LED transformer is the best way to drive LEDs. It uses constant current source to drive. There is no need to connect a current-limiting resistor in the output circuit. The current flowing through the LED is not affected by chang...

How to connect an LED power supply

Wiring a red LED strip (or any other monochromatic LED strip) couldn't be easier. Just connect your 100-277Vac main best led power supply (+ve and -ve cables) to the input terminal of the led strip driver, and then connect the starter leads of the LED light bar (again +ve and -ve) to the led strip driver output terminals. For more guidance, please refer to the "Power Supply for a Monochrome LED St...

What is the switching frequency of a power supply?

The switching frequency refers to the rate at which the DC voltage is turned on and off during the pulse width modulation process in the 277vac class 2 power supply. The switching frequency in the inverter is the rate at which the switching device turns on and off. The typical frequency ranges from a few KHz to a few MHz. The increased switching frequency not only reduces the space requirements of...

What is the certificate for your 0-10V dimmer?

Our 0-10v dimmer has CE and ROHS certificate. The dimming mode is 0-10V analog signal. Its input voltage range is 100-265Vac. The output voltage range is DC 0-10V, its output current is 50mA. They are all compatible and dimming well with 24v 0-10v dimmable led driver. We got two types dimmable function, one is 0-10V Rotary Dimmer. When you twisting the knob meanwhile it start to control 0-10V sign...
