Operating LED modules (How do I operate an LED module correctly?)
LED modules are essentially available in two designs – as constant current control modules and as constant voltage control modules. Constant current control modules do not have current stabilising switching on the PCB. The current is stabilised by the control gear. When choosing the right control gear, you must pay attention to the correct supply voltage range and the operating current. Typical product lines include the VS PowerEmitter, LED modules for shop lighting, Mini / Line / Spot, M class, etc…
Constant voltage control modules require a stable voltage for operation. This voltage is usually 24V. There are additional electronics on the LED modules to regulate the current through the LED. Typical product series are the LEDLine Flex, LEDLine CoB or HighPower 24V CA System.
