SpikeSafe Current Source Selector Guides

SpikeSafe Series Current Sources offer unparalleled power, accuracy, and reliability. The series includes models supporting DC/constant current only, DC and pulsed current, and DC/pulsed models with advanced dynamic modes that speed production testing and device characterization. All models include Vektrex’s continuous power conversion technology that provides high power output over the source’s full performance envelope. Single and multichannel models are available with maximum current ratings from 500mA to 50A and with maximum operating voltages from 50V to 400V. These features make them ideal choices for a wide range of LED and laser diode applications.

DC / Constant Current Only:

1-8 independently controllable source channels, up to 50A, 400V: Vektrex DC Current Source Selector Guide

Applications:

  • LED/laser diode reliability testing
  • Burn-in
  • HASS and LM-80 applications
  • Calibration lamp drive

DC / Continuous Pulse Current:

1-8 independently controllable source channels, up to 40A, 400V: Vektrex DC Continuous Pulse Current Source Selector Guide

Applications:

  • LED/laser reliability testing
  • Other applications requiring DC and/or pulsed current

DC / Pulsed / Performance Current Sources:

For demanding applications SpikeSafe Performance Pulsed current sources will be most appropriate. These models include all of the features of DC/Pulsing models and add specialized current modes, dynamic current changes and synchronized triggering. Additional options such as modulated DC current output, and bias current options support temperature at the junction (TJ), thermal modelling and non-DC waveform testing.
