UHPTLCC-02: Benchtop UHP-T-LED Controllers

The UHPTLCC controllers compatible with any of the five product lines of Prizmatix Ultra-High-Power collimated LEDs: UHP-T-EP, UHP-T-SR, UHP-T-DI, UHP-T-LA and UHP-T-MP.

 Analog LED controller for basic  control functions.                                                                     
 USB Computer Interface:
 Digital LED controller enabling  control from computer via USB  and power monitoring by digital  photodiode.
 Digital controller with power  stabilization by photodiode and  PID algorithm.                                              

Remark: UHPTLCC-02 is advanced version of UHPTLCC Legacy controller.

Any UHP-T series LEDs can be used with any UHPTLCC-02 series controller. Advanced high current driver is embedded within the shielded LED head, not in the controller box. The UHPTLCC-02 controller contains all control interfaces and functions.
This split arrangement allows direct mounting of LEDs on sensitive equipment while eliminating virtually all RFI / EMI interference common in high current light sources.
All BNC connectors for TTL and Analog inputs are Optically Isolated to prevent ground loops interference at data recording.

(1) Optically Isolated TTL input levels are:

  • LED On: 3.0V to 5.0V
  • LED Off: below 1V

(2) Analog Input (0 to +5V) can be useful for LED power control from external DAC such as      NI-USB-6001.
