Digimax: DC LED driver for industrial applications

Constant current LED drivers are designed to maintain a stable current value (e.g. 350mA or 700mA), automatically adapting the output voltage based on the connected load: this ensures constant brightness while protecting the LEDs from damage, overcurrent and overheating.

Key Advantages of DC LED Power Supplies:

- Stability of brightness even with variations in temperature or cable length;

- Overcurrent protection for longer LED life;

- Suitable for powering single LEDs or modules in series.

Application areas of constant current LED drivers:

- Industrial and commercial lighting (spotlights, projectors and signs);

- Street and public lighting (LED street lamps, tunnels, etc);

- Specialized sectors (museums, shops or particular scenography).

What is a constant current LED power supply?

A constant current (DC) LED driver is a power supply that provides a stable electrical current to the LEDs, regardless of voltage variations: this ensures consistently uniform brightness and protects the LEDs from damage due to overcurrent or overheating.

What are the differences between constant current or constant voltage LED drivers?

Constant current LED power supplies regulate current flow regardless of output voltage or AC/DC conversion; Instead, constant voltage (CV) LED drivers maintain a fixed voltage and let the current vary based on the load.

How to choose a constant current LED power supply?

To choose the most suitable DC LED driver, it is necessary to consider some elements: the output current, which must be compatible with the LEDs to be powered (e.g. 350mA, 700mA, 1050mA, etc.), the output voltage range to guarantee correct operation, the total power required based on the LEDs connected, the IP protection degree if intended for internal or external environments, compatibility with dimming systems if it will be necessary to regulate the light intensity.

Are constant current LED drivers both AC/DC and DC/DC?

A constant current LED driver can be configured as AC/DC or DC/DC, depending on the power source and specific application. A constant current AC/DC LED power supply converts the alternating current of the electrical network into direct current, in order to power the LED systems directly from the mains; otherwise, a constant current DC/DC LED driver transforms one voltage into another, maintaining constant current and precise light regulation.
