The Model 6100 unit contains circuitry to minimize the impact of power line

surges. In order to further protect an attached laser diodes and TEC coolers,

the 6100 contains circuitry to immediately shut down one or both of the

outputs when a large surge is detected.

This secondary protection capability instantly disables an output when it

senses that the output's current exceeds 3% of the set current limit or that the
