- Model: SFA Series
- Voltage: 60V - 160V
- Current: 31A - 500A
- Power: 5kW - 30kW
- Overview: High Slew Rate Current Source
SFA Series - High Slew Rate DC Current SourceSFA
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.
