LED Drivers & Power Supplies

An LED driver (also called an LED power supply or transformer) converts mains power to the low voltage your LED strip needs. The right driver keeps the light stable, flicker-free and long-lasting. We stock over 190 models from trusted brands such as Mean Well and Helvar.

How to size a driver

Multiply the strip's power (W/m) by its length and add a 20% reserve. Example: 5 m × 10 W/m = 50 W, so choose a 60 W driver. Make sure the voltage matches the strip: 12V, 24V or 48V.

Dimmable drivers

  • TRIAC: works with standard wall dimmers.
  • PUSH DIM: dims with an ordinary push button.
  • DALI and 1–10V: for building automation and professional projects.
  • Zigbee: for smart home control.

Indoor or outdoor

Choose IP20 for dry, enclosed spaces and IP67 for outdoors, bathrooms and other damp locations.

Frequently asked questions

Is an LED driver the same as a transformer?

In everyday language yes. Technically, LED strips need a constant voltage driver.

Usein kysytyt kysymykset

Millainen muuntaja LED-nauhalle tarvitaan?

Muuntajan jännite on sama kuin LED-nauhan, eli 12 V nauhalle 12 V muuntaja ja 24 V nauhalle 24 V muuntaja. Teho valitaan 20–30 % nauhan kokonaistehoa suuremmaksi.

Miten lasken muuntajan tehon?

Kerro nauhan teho metreillä: esimerkiksi 5 m × 10 W/m = 50 W. Sopiva muuntaja on silloin 60–65 W.

Kumpi on parempi, 12 V vai 24 V?

24 V sopii pidempiin vetoihin, koska jännitehäviö on pienempi. 12 V on yleinen lyhyissä kalustevaloissa ja vanhoissa järjestelmissä.

Voiko LED-muuntajaa himmentää?

Kyllä, kun valitset himmennettävän mallin: TRIAC tavallisille seinähimmentimille, DALI ja 1–10 V ohjausjärjestelmiin, Push Dim painonapille. RF-himmentimen kanssa riittää tavallinen muuntaja.

Tarvitaanko ulos tai kylpyhuoneeseen erityinen muuntaja?

Kosteisiin ja ulkotiloihin valitaan IP-suojattu muuntaja, ulkokäyttöön IP67.

Mikä ero on vakiovirta- ja vakiojännitemuuntajalla?

Vakiojännitemuuntaja (12/24 V) on LED-nauhoille. Vakiovirtamuuntaja on alasvaloille ja spoteille, joiden tuotetiedoissa sitä vaaditaan.




LED-In the choice of

When choosing a transformer, always take into account LED: the number of groanes, since only a certain amount of a single transformer can be connected LED: E.g. 18W 24v LEDto Fits 24v power supply and assume you make a uniform 4M LEDtape pull. Calculations LED-In the transformer's power: 18W x 4m = 72W, ie select 100W 24V standard voltage sourcein order to have a transformer power of 20-30% higher than the calculated power requirement required by LEDs.
