40A DC Current Source

The SpikeSafe 40A DC Current Source supports LED reliability, burn-in test, IESNA LM-80 and other applications. It provides reliable and accurate current drive at compliance voltages up to 200V. This capability makes the SS400 DC 40A an ideal choice to power series circuits containing multiple high current devices.

Each source channel delivers up to 6400W 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.

Multiple output conductor pairs keep maximum current per conductor below 5A, allowing the current output to be routed through standard interconnect devices.

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.
