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.

Applications
Process Control
Whether you are controlling ion beams for the manufacturer of semiconductors or driving a solution for precise control in a plating process, the SG series variable DC power supply is an ideal choice with its small size, reliable modular design, and standard analog programmability.
Direct control of V and I along with 0-10V outputs allowing monitoring of the actual voltage and current, provides a simple interface for your PLC or other type of analog controller.
Product Development
Testing & Burn-in DC-DC converters, laser diodes, automotive and semiconductor components, and aircraft flight hardware are just a few of the items being tested using the SG product family.
From simple front panel control to complex test sequences for compliance testing, the SG series DC constant current source will grow with your product needs.
Research
A research environment presents some of the most demanding requirements for your test instrumentation. Equipment that is sufficient today, may not meet the needs of the next project. With the SG series DC power testing system, this is no longer a problem.
The modular design allows you to easily upgrade to higher power levels in the future, or parallel units to achieve up to 150 kW. With the sophisticated sequencing capability of the SGI model, you can build an infinite variety of test or diagnostic programs and have them execute directly from the power supply.
Automotive Component Test
The 16-bit resolution of the Ethernet programming and hardware triggering allows for detailed sequencing associated with battery fluctuation simulation. The tight load regulation capability of the SG series makes it a superior source for validation and acceptance testing and burn-in of automotive components.
The 40V models provide a full range of testing to simulate battery conditions. Margin testing of 12V and 14V nominal components, such as electronic control units (ECU) and electromechanical components, is easily achieved.
Rackmount ATE Systems
The high-power density of the SG series DC power supply makes it ideal for ATE System integration. The wide variety of voltage and current combinations in 3U and 6U heights allows multiple voltage outputs in a small amount of space.
The wide variety of control methods possible allows easy integration into legacy systems as well as high-speed systems.
Battery Charging
The SG series programmable DC power supplies provide high-accuracy voltage output to optimize battery charging. Battery charging requires high accuracy voltage and stable current output for fast bulk and absorption phase charging and high accuracy and stable voltage for float charging to avoid “gassing” the battery. With the remote interface options, the charging process can easily be automated for volume production.
