Controllable and adjustable LED illumination power source

The LED controller is a multi-channel, cascadable power source for LEDs. Instructions to the controller can transmitted over different interfaces.

Pulse width modulation  (PWM) with powerful filter levels ensures high dynamic  with low lost heat generation and extreme low ripple. The embedded micro controller in conjunction with A/D converter allows parametric control processing.

 Controller modi

There are 3 controller modi :

1.  Control mode

    Direct controlling of the LED channels
    witch instructions over PC

2.  Auto control mode
    A.     internal power sensor
    B.    external  irradiation sensor
    Controlling of the LED channels takes place
    according to the parameters

3.  Burst mode

    The power impuls is started over
    external trigger. Length of the impulse
    is given from PC.
