The SpikeSafe 500mA DC Current Source supports LED reliability, burn-in test, IESNA LM-80 and other applications requiring multiple drive channels operating at high voltages and low currents. This model has Vektrex’s lowest recommended minimum current; it can accurately drive into the microamp range.
The SS400 DC 500mA provides 8 independent source channels of reliable and accurate current drive at compliance voltages up to 400V. This high voltage capability makes it an ideal choice to power series circuits containing multiple devices.
Each source channel delivers up to 200W of output power at an industry-leading 96% power conversion efficiency. High efficiency reduces electricity and cooling needs, lowering the total cost of ownership for systems incorporating the SS400.
Built-in voltage and current readback circuits support LM-80 monitoring requirements. Devices being tested are protected with a gentle turn-on during ramp-up, and with SpikeSafe™ load protection during operation.

System Configuration Options
SpikeSafe DC Current Sources are available in a self-contained 2U rack-mountable chassis that holds one module, or in multi-module rack systems that house up to 8, 24 or 32 modules. Scalable, modular design enables easy system expansion for increased capacity or specialized test performance.
Additional Features and Software
SpikeSafe Current Sources run on economical bulk DC power. Consult Vektrex to select the appropriate bulk power supply for your application.
SpikeSafe load protection continuously monitors voltage and current patterns and instantly shuts down drive when device anomalies are detected.
Optional SpikeSafe Test and Reliability Software (STARS) controls and monitors 1 to 32 SpikeSafe modules. STARS supports source setup, data logging, error monitoring, test timing, and power cycling.
