RS-4 Constant Current Lamp Power Supply

The Gamma Scientific RS-4 power supply is a precise, current-regulated power supply intended for use in light measurement applications. Most often paired with calibrated standard lamps or LEDs, this power supply maintains output stability over long time periods, and the entire unit is resistant to changes in the environment. This allows any calibration established in a test lab to be conserved when transporting to other locations.

A ramping function maximizes the life of the light source by gradually changing current output from 0% to 100% over 30 seconds. This function is accessible on the front panel via an enable button or can be triggered remotely using the TTL logic function.

 

Applications

  • Driver for calibration standard lamps
  • Projection light source controller
  • SSL  and LED operation
  • Other test and calibration application
