What you need to know about LED drivers?

Dimmable Junction Box LED Driver, can be used directly to meet U.S.A. Canada standard, input 100-277Vac,7 Years Warranty, UL ETL Class2 Class P T24 standard, Works with CCT led strip 2/3 wires Warm-white color temperature, VR+PWM output Fine-turning Function(avoid voltage drop), not change the color index, Dimming/Loading:0.01-100%. power factor up to 0.98, work with triac/Forward and Reverse phase( Leading and trailing edge) MLV/ELV dimmer and 0/1-10V dimmer, output wattage range is 30-384W.

 


High voltage 225VDC LED driver, 7 Years Warranty, 100-277Vac/220-240Vac 150W 200W 400W 120Vdc 225Vdc output, Support Dali/DMX/0-10V/triac/5 in 1 Dimming, High voltage light strip flicker free because of Ottima LED Driver, Strobe is serious if you don’t use any driver.

 


200-347VAC 60-300w Max LED Driver for industry use, Supports 0-10V, DMX, DALI (D4i) Slim size Suitable for small spaces, NFC Function can Selectable output mode, frequency, curve and supports fine-tuning voltage, 7 years warranty, power consumption≤0.5W PF≥0.95


In addition. The LED driving power supply is a transformer, it can convert the input of high-voltage industrial frequency alternating current, low-voltage direct current, high-voltage direct current, or low-voltage high-frequency alternating current into the current and voltage required, then customer can use it normally so that the LED lighting product can glow and work normally. The LED driver not only improves the luminous efficiency, product stability, and reliability of LED lighting products but also protects the lamps and extends their life.

 

The main functions of LED driver include: Controlling the brightness and current value of the LED to ensure that it emits light within the normal operating range while protecting the LED from voltage and current fluctuations. Improve the light efficiency of LED and reduce power consumption to a certain extent.

 

High efficiency, reducing energy consumption and heat generation, helping to delay the light decay of LEDs. High power factor, reducing impact and pollution on the power grid.

 

Our products have surge protection to prevent surge damage to LEDs caused by the startup of grid loads and external factors such as lightning strikes.

 

There is over-temperature protection to prevent the LED temperature from being too high and protect the stable operation of the LED.

 

Ensure the efficient and stable operation of LED lighting products.

 

IP67 all-aluminum shell waterproof 7-year warranty, high reliability. LED streetlights are installed at high altitudes. If the quality is good, they will not break easily, reducing the number of repairs. The glue filling is good for heat dissipation, high efficiency, low power consumption, and low heat generation in the lamp. This also reduces the temperature rise of the lamp. It is beneficial to delay the light decay of LED. Because the luminous efficiency of LEDs decreases as the temperature of the LED increases, the heat dissipation of the LED is very important.


High power factor PF>0.95, different countries have different requirements of power factor. Generally, there without requirement below 70 watts.

 

In terms of protection, if the lamp is installed externally, the power supply structure must be waterproof and moisture-proof, and the outer casing must be light-resistant.

 

The life of the driving power supply must match the life of the LED

 

Our product is it meets electromagnetic standards and low-output voltage safety regulations

 

For Constant voltage series:

a. After confirming the parameters in the voltage stabilizing circuit, the output voltage did not change, the output current will be changed based on the load

b. The voltage stabilizing circuit does not allow the load to be completely short-circuited, and it not afraid of the load opening

c. Use a constant voltage drive circuit to drive LEDs.

d. Brightness will be affected by voltage changes from rectification

 

Pulse driving Many LED applications require dimming capabilities, such as LED backlighting or architectural lighting dimming. The dimming function can be achieved by adjusting the brightness and contrast of the LED. Simply reducing the current of the device may be able to adjust the LED light emission, but operating the LED below the rated current will cause many undesirable consequences, such as chromatic aberration problems. An alternative to simple current regulation is to integrate a pulse-width modulation (PWM) controller into the LED driver. The PWM signal is not used directly to control the LED, but to control a switch, such as a MOSFET, to provide the required current to the LED. PWM controllers typically operate at a fixed frequency and adjust the pulse width to match the required duty cycle. Most current LED chips use PWM to control LED light emission. To ensure that people do not feel obvious flickering, the frequency of PWM pulses must be greater than 100HZ. The main advantage of PWM control is that the dimming current through PWM is more accurate and minimizes the color difference when the LED emits light.

 

External power supply, the power supply is installed outside. Generally, an external power supply is required if the voltage is relatively high and poses a safety hazard to people. The difference from the built-in power supply is that the power supply has a casing. Common ones include street lights.

 

The built-in power supply means that the power supply is installed inside the lamp. Generally, the voltage is relatively low, 12v to 24v, and there is no safety hazard to people. This common lamp has a bulb.

 

Power LED driving power supply is mainly used for outdoor high-power LED lighting equipment such as LED street lights, tunnel lights, subway (light rail) lights, etc. It is a type of switching power supply. Its function is to convert AC mains power into DC power. , while completing the matching of voltage and current with high-power LED. LED driving power supply is mainly used as supporting equipment for LED lighting equipment. our led driver product output wattage 600W max
