  • Minimum current ripple and LED brightness fluctuation during optical test
  • Low current overshoot while shorting LED
  • Overheat protection

Product description

Current source is designed as power supply and test equipment for single LED or strings (modules), which does not contain circuits for current regulation. It is possible to set required current and measure voltage on LED with simple text commands. For both current and voltage there are adjustable limits which prevents exceeding LEDs maximum ratings.

In addition to standard mode with PC communication, current source offers autonomous mode too. Required current and limits are set before testing and stored in memory. Tests are started with digital inputs; current source then evaluates if the LED module is in range of limits and signalizes the result (OK/NOK) with digital outputs.

For modules containing more LED strings with common cathode it is possible to use simultaneously several current sources and set their currents individually. For current regulation the anode voltage is changed while cathode stays at the same potential.

  2. Supply voltage 24 V. Actual power consumption depends on output current and parameter settings.
  3. Provided the same temperature of source is maintained.

Ordering information

Order number Product code Description
60263010 CS01-035 Current source for LED testing, 25 mA – 350 mA
60263002 CS01-200 Current source for LED testing, 100 mA – 2 A
80140000 CS-035 - Discontinued Current source for LED testing, 25 mA – 350 mA
