LED converter = "converter" for LED? What is it?

This term describes in general the conversion of 230V alternating voltage to a size common for the operation of LEDs. This means that the LED converter converts from 230V to 12V or 24V voltage or if necessary to e.g. 350mA constant current.
Further distinctions are LED transformer = constant voltage source or LED driver = constant current source.

You can find what you are looking for more quickly via the pre-selected selection of LED converters for the respective categories.
If the LED converter is to be dimmable, you can quickly find the type you are looking for using the filter options.

LED Converter for 12V or 24V from 230V

12V or 24V DC voltage?

then you are probably looking for a converter for the operation of LED strips, LED strips or other LED modules, because these already have an electronic converter integrated as a constant current source.

We gladly recommend the PWM series from Meanwell, because here the dimming is designed to be exceptionally well-featured.

12V AC voltage?

That is already special and there is only one use case: Operation of 12V retrofit lamps. In the meantime, however, most manufacturers have developed these so that they can also be operated with 12V DC. Please pay attention to the technical imprints.

LED converter for e.g. 350mA or 700mA constant current

In this case these are LED drivers, which "drive" a limited current through the LEDs. Often also referred to as constant current sources. Applications are often recessed ceiling spotlights or integrated in luminaires designed as a ballast for the LED modules (power LEDs or COB modules).

Many of our converters are universally adjustable, or can be selected according to criteria:

Dip switches of the LED converter (models of TCI) can be used to set different currents.
Large selection of universal LED converters with output currents from 250mA, 350mA, 500mA, 600mA, 700mA, 900mA to a maximum of 1.05A.
Many LED converters can be dimmed via DALI, 1-10V, push button, Zigbee, Bluetooth (Casamb) functions or even Triac.

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.

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).

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.

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).
