SFA Series

The SFA family builds on the industry-leading Sorensen SGA series to provide a high-power DC current source for laser diode applications. State-of-the-art high-power laser diodes require well-regulated current control to avoid catastrophic damage. Under anomalous operating conditions, excessive stored energy in the output circuit of the DC power supply can result in peak stresses that can permanently damage the device.

Providing a constant current regulation mode only, the SFA’s low stored energy output minimizes damage potential for sensitive devices as well as enables a current slew rate of up to 400 A/msec.
