DC current source SpikeSafe

Vektrex SpikeSafe DC / Continuous Pulse Current Sources provide reliable DC constant current or precision pulsed current drive. These pulsed current sources are optimized for reliability and burn-in testing and other test applications requiring DC constant current or continuous pulse current. They are applicable for LED, VCSEL, laser diode and other current driven devices. With a wide range of single and multi-source channel models, the SpikeSafe DC / Continuous Pulse Series current sources will meet the needs of a full product family. Moreover, all models are energy efficient and feature individual source channel control and accurate currents to the ends of long cables. Minimum pulse widths are 10us. The power density is high – typically 6.4kW to 8kW. Vektrex’s patented SpikeSafe technology protects devices in two ways: by proactively detecting current anomalies and rapidly shutting down power to preserve devices and by tightly regulating the voltage. Accurate Pulsing Over Long Cables Adjustable load tuning allows the SpikeSafe to compensate for load conditions, cable impedance, and length. The resulting fast, clean pulses have little overshoot – even with output cables over 10 meters long. Using the SpikeSafe makes it easy to duplicate real-world pulsed operation test conditions – for example 720 Hz PWM operation at 1% duty cycle. Twisted Pair Output Wiring Simplifies System Unlike other precision pulsed sources that require exotic coaxial or flat ribbon output cables, the SpikeSafe 400 DC / Continuous Pulse current source use simple, low-cost twisted pair output wiring.
