40w 800ma led driver

Types of 40W 800mA LED Driver

40W 800mA LED drivers are categorized into three main groups. These groups are based on how the drivers are controlled, powered, and constructed. The groups are as follows;

• Non-Dimmable LED driver

  Non-dimmable LED drivers are light sources that are not compatible with dimming. As a result, the brightness level remains constant. Additionally, they are simple, economical, and efficient.

• Dimmable LED driver

  These drivers provide an opportunity to control the brightness level of the lights. They come with different kinds of dimming options such as;

  1-10V dimming

  The 1-10V dimming driver allows for simple and cost-effective dimming. It is compatible with 1-10V dimming signals. The signals are sent from a control device to the LED driver. The control device can be a potentiometer, slider, or dimmer switch. The level of LED lighting varies depending on the voltage level of the dimming signal. For example, a 1V signal can be associated with a lower brightness level. On the other hand, a 10V signal indicates higher brightness.

  DALI dimming

  DALI dimming drivers support dimming by the DALI protocol. The DALI protocol is a standardized communication network for lighting control. The DALI dimming driver is connected to a DALI master. It can be a sensor, switch, or lighting control system. The master communicates with and controls multiple DALI drivers. Each driver has its own address within the DALI network. The DALI system is capable of creating different lighting solutions. It also provides reports on energy consumption and individual driver status.

  PWM dimming

  PWM dimming LED drivers utilize pulse-width modulation to control brightness. The dimming signal is a rectangular wave. It has varying duty cycles. The average power delivered to the LED is determined by the duty cycle. A higher average power means higher brightness. A lower average power translates to lower LED brightness. The structure of the PWM signal remains constant. It can be used with different kinds of LEDs and lighting applications.

How to choose 40W 800mA LED driver

Choosing the right LED driver depends on various factors. Below are some of the factors business owners should consider when choosing an LED driver.

• Consider the LED configuration

  When choosing an LED driver, it is important to consider the LED configuration. This means determining whether the LEDs are in series or parallel. Knowing their configuration will help in selecting a driver that is compatible with the LED setup. For instance, a 40W 800mA LED driver is suitable for several series LEDs with a total forward voltage of around 32 to 40 volts. It can also be used for multiple parallel strings of LEDs if each string has a similar voltage and forward current.

• Consider the dimming options

  The good thing about LED drivers is that some come with dimming capabilities. For users who want to adjust the brightness of their LEDs, they should get a driver with dimming options. Such drivers support various dimming methods like analog dimming, PWM and 0-10V. Also, they support digital dimming protocols like DALI and DMX.

• Output current

  The output current is one of the most important specifications of an LED driver. It defines the amount of current the driver provides to the LED light. Therefore, when choosing an LED driver, business owners should select a driver with an output current that matches the LED light’s specifications. An output current that is too high can damage the LEDs, while one that is too low will result in insufficient brightness.

• Output voltage

  Similar to the output current, the output voltage of an LED driver has to match the LED’s requirements. The output voltage determines the amount of voltage the driver converts and provides to power the LED light. If the output voltage is not compatible with the LED light, it can lead to LED failure. Therefore, it is important to check the LED driver specifications before settling for one.

• Consider the power rating
