LED constant current sources

LED power supply with constant current for your LED projects of LED Professional!

By means of constant current LED power supply units, it is possible to supply various forms of high power LEDs with a constant current supply.
LEDs have a completely separate behavior. The characteristic curve already causes large current changes even with small voltage fluctuations.
Even with a 1 watt LED, the voltage is accurate with e.g. 2.86 volts constant to maintain a diode current of approx. 350mA, the operation is not stable. The characteristic curve of the LEDs constantly changes as a function of the operating temperature and aging and differs from diode to diode. Safe operation is not possible and thermal destruction is possible quickly with small fluctuations.
For this reason, constant current sources, so-called LED drivers, are used. This constant current source controls and is limited to a constant current, for example 350mA or 700mA. The voltage varies depending on the performance. When operating at a constant current source, the LED is always operated with a constant current. The current control is integrated in the power supply.
The operation on high-quality LED constant current power supplies with constant current offers the better efficiency and longevity of your LEDs. The connection of LEDs to a driver usually takes place in series. The LEDs should always read the operating instructions carefully
In our range of the LED Shop lighting solution, you will find numerous suitable professional power supplies for your applications.
