LED power supply - This can be anything, but also quite special.
Basically, the term "power supply" is derived from a device that is operated between the 230V mains supply and here an LED system. (cf. LED ballast)
However, the designs/characteristics of the so-called LED power supply differ by a variety of Parameters.
- LED driver/constant current source or constant voltage LED transformer?
- Dimmable via power line itself (phase cut dimming) or external dimming input, such as DALI/1-10V or radio?
- LED drivers are determined by constant current values such as 350mA/700mA etc.
- LED transformer are understood as fixed voltage power supply with constant DC voltages like 12V, 24V, 48V etc.
- Output power with specifications in watts.
We have created a selection guide with navigation. So everyone can quickly find his suitable LED power supply.

Guideline: Which power supply for which application?
Power supply buying guide - Find the right and best power supply for your LED system
In the following table we explain what is important and what the main differences are. Basically all LED DC power supplies must comply with DIN61347. Only then they are allowed to be used with LEDs. A feature we pay attention to.
| Power supply types | LED transformer Constant voltage power supply*) | LED driver Constant current power supply |
| Main feature: Voltage (Volt) | impressed/fixed, constant. Example values: 12Volt, 24V, 48V | depending on the connected LED module, LED spot, LED string. Specifications correspond to a "working range", determined by the number of LEDs. (independent of the current). Example values: 350mA/700mA .... 1050mA |
| Main feature: Current (amps, milliamps) | depending on the number and power of the connected e.g. LED strips. (can be set to a max. value with some power supplies). | set current is fixed. Drives (!) a defined current through the LED string. |
| Power (Watt) | 16W to 600W | 1,4W to 100W |
| Areas of application: | Low voltage LED modules, LED boards with integrated electronics for the LEDs. Main application: LED strips, LED strips, as well as their control electronics. | Pure COB LED chips, LED ceiling recessed spotlights, LED boards in luminaires for direct constant current operation. It is mandatory to pay attention to the current specification. |
| Flicker/Dimming | Output brightness control via PWM (pulse width control). Flicker depending on modulation method and frequency. | Mostly PWM control, is increasingly replaced by versch. innovative solutions such as hybrid dimming or completely flicker-free linear control (AM, - amplitude modulation). (Look for the "AM" symbol). |
| Light control | For both types brightness control via common technologies such as phase dimming, DALI, 0/1-10V, touch dimming, or control via radio (Casambi, Bluetooth, Enocean, Zigbee) is possible. (Use our filter function to quickly narrow down) | |
| Housing | Available housing forms are sheet metal, aluminum and plastic housings, fully encapsulated with high IP protection, as a device with strain relief (for e.g. operation as an external power supply in false ceilings) or as a recessed version for integration into an LED luminaire system. Versions in plug form, top-hat rail or box installation are also available. | |
| Cooling | All our devices in the store are quiet power supplies and work with passive cooling. During operation, we recommend compliance with the test point Tc specified maximum temperature. This ensures a long service life. | |
| Power supply manufacturer in store (only renowned Brands) | Meanwell, Pur-LED, Arditi, Lunatone, TCI, Eldoled, Enertex, Code Mercenaries, Tridonic | |
| alternative names | LED power supply, LED transformer, DC power supply, mains transformer, transformer power supply, fixed voltage power supply, electronic transformer, constant voltage source | Constant current source, constant current Driver, |
*) Attention: These are direct current (DC) power supplies and differ in application from alternating current transformers as with specifications of 12V AC.
It is imperative to pay attention to the exact specification on the lamp.

Why are there so many different LED power supply units?
In the past, there were lamps for operation on 230V (HV) or also for e.g. 12V low voltage. The lamps were designed accordingly and could be easily replaced.
To operate 12V lamps, for example, a power supply unit, or transformer for short, was required to transform the 230V voltage to 12V.
With the advent of LED technology, many new operating modes became established.
Replacement LED lamps in particular (e.g. with GU5.3 base) still require a transformer. So-called LED transformers were developed due to the now lower output and a previously high minimum load. While other LED concepts are replacing the LED lamps for replacement and producing special LED drivers for direct operation of the LEDs.
What is the difference between an LED transformer and an LED driver?
LED transformers are specially designed for constant voltage operation of LED systems and supply a fixed voltage at the output, e.g. 12V or 24V.
A distinction is also made here between 12VAC (for e.g. 12V LED lamps, usually referred to as retrofit lamps) or 12V DC or 24V DC for operating mostly LED strips/LED tapes.
The voltage is constant (CV=constant voltage) and the current (mA) depends on the power of the connected lamps.
LED drivers, on the other hand, provide a constant current (e.g. 350mA). The reason for this is the special (U/I) characteristic curve of a diode, especially a light-emitting diode (LED). If operated with a constant voltage, the current would change considerably, even to the point of destruction, in the event of the slightest instability in the voltage or even ageing or temperature changes. For this reason, the current is limited or kept constant. An LED driver drives a constant current through the LED(or several LEDs connected in series). The voltage that then "drops" at the LED ("forward voltage") or the sum of these is then the voltage measured at the output of a driver. The power supply unit must be able to provide this. This is why voltage ranges are often specified here. The current is constant (CC=constant current) and the voltage depends on the characteristics of the LED system (number of LEDs).
