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). |
LichtsteuerungLichtsteuerungLight 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. |
