Vektrex SpikeSafe™ DC Current Sources provide reliable precise constant current drive. Available in single and multiple source channel instruments, these tools are used worldwide in LED/laser diode reliability, burn-in, IESNA LM-80 test, and other current-driven applications. For applications requiring measurement, please refer to SpikeSafe Source Measure Unit.
SpikeSafe DC Current Source models supply constant current up to 60A and max compliance voltages to 400V. The high compliance voltage capability and SpikeSafe load protection allow many devices to be tested in one series circuit. This configuration is much more efficient than traditional single device circuits. The net result is lower annual operating cost and lower total cost of ownership.
All models feature individual channel control, precise current, and high power density — typically 6.4kW-8kW. Use of long cables to 12m is applicable for all SpikeSafe source instruments.

SpikeSafe current sources are easily combined into systems with up to 1,024 current source channels in an electronics cabinet. Scalable, modular design enables easy system expansion for increased capacity. With a full range of SpikeSafe™ current source options, system components, chambers, fixturing, load board designs, cabling and software, Vektrex can provide the ideal testing solution for any size lab – large or small.
Vektrex’s easy-to-use SpikeSafe™ Test and Reliability Software (STARS) controls and monitors sources, loads and thermal control devices during testing. With STARS, long-term reliability and burn-in tests can be automated and unattended. STARS supports independent source channel startup and shutdown, allowing multiple LED batch runs on a single system for optimized throughput. Stand-alone STARPLOT plotting software provides a graphic view of voltage, current and temperature data to quickly identify and illustrate trends.
Vektrex’s patented SpikeSafe™ load protection continuously monitors voltage and current patterns and instantly shuts down when anomalies are detected. Rapid shutdown preserves the failed device for analysis, and it protects other devices in the circuit. The result is lower failure counts and improved reliability statistics.
SpikeSafe current sources operate at 98% conversion efficiency. This high efficiency reduces electricity usage and it minimizes the heat released into the laboratory. In addition, the current sources’ high compliance voltage capability and SpikeSafe load protection allow many devices to be tested in one series circuit. This configuration is much more efficient than traditional single device circuits. The net result is lower annual operating cost and lower total cost of ownership.
