LED Light Source Control Unit
LED Light Source Control Unit
The LED light source control unit is a line powered constant-current source designed for Thomas LED Light sources. This device provides a constant current of up to 1000mA to guarantee a stable light emission from the LED light source.
It is possible to adjust the light intensity manually by turning a potentiometer at the front panel of the device and reading the adjusted current value from an integrated moving coil instrument. Furthermore the light intensity can be controlled by a DC input of the device (0…5V DC = 0…100% Light intensity) by using an external DC voltage (e.g. from a PC insert card). A trigger input offers to switch the light source “on” and “off” by an external TTL trigger signal.
Key features:- Power Supply for high brightness LED technique
