3A DC Current Source

The SpikeSafe 3A DC Current Source is part of the SpikeSafe DC Current Source family. This current source supports LED reliability, burn-in test, IESNA LM-80 and other applications requiring multiple drive channels. It provides 8 independent source channels of reliable and accurate current drive at compliance voltages up to 400V. This high voltage capability makes the SS400 DC 3A an ideal choice to power series circuits containing multiple devices. Each source channel delivers up to 1000W 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.

Vektrex develops software applications for DC current sources including: Control Panel Software Application and STARS (SpikeSafe Test and Reliability System). Control Panel Software Application provides a user interface to the SpikeSafe current source enabling use out of the box. STARS is designed for high capacity system usage.

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.

The notable specifications for this current source are as follows: the minimum recommended current compliant with LM-80 3% accuracy requirement is 5.9mA. The nominal current ripple is 0.03% + 300uA. The low current range to 200mA output current accuracy is 0.04% + 175uA and the high current range to 3A output current accuracy is 0.14% + 2mA. 

3A Performance Curves

This model is available for use with an internal power supply (300W or 600W). For total output power across 8 source channels (8 x 1kW = 8,000W), an auxiliary power supply is required. Please consult Vektrex for auxiliary power supply recommendations.
