|Power supply types ||LED transformer |
Constant voltage power supply*)
|LED driver |
Constant current power supply
|Main feature: |
|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. |

|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. |
