Keithley 2268-80-10 Power Supply
High-Efficiency DC Power Supply, 80V, 10.5A, 850W
The Keithley 2268-80-10 Power Supply is engineered for robust performance in demanding applications, supporting up to 30 Series 2268 units through a single master interface, thanks to the integrated RS-485 connectivity. This allows seamless control and management of multiple supplies, optimizing your test setup with efficiency.
This powerhouse offers additional versatility with two auxiliary outputs at 15V and 5V, perfect for signaling and control tasks, such as powering external devices or relays without the need for extra equipment. This feature is especially advantageous in environments where space and resources are at a premium.
Enhance Your Power Capacity
The 2268-80-10 allows for flexible configurations; you can seamlessly connect up to two units in series for higher voltage demands or four in parallel to satisfy greater current needs. Utilizing analog control lines, these units can be organized in a master-slave layout, ensuring comprehensive safety settings across all connected supplies.
Safety and Protection Features
Designed with safety in mind, the power supply incorporates dual protection parameters for both the load and the supply itself. It features adjustable over-voltage and under-voltage shutdown levels, alongside over-current safeguards to prevent potential damage. The integrated over-temperature limit further enhances protection by monitoring temperatures to avert harmful conditions.
The Keithley 2268-80-10 also includes a foldback function, with a programmable delay feature that prevents premature shutdown during conditions where high in-rush currents may trigger a quick switch between constant voltage (CV) and constant current (CC) modes. This thoughtful design enables your load to stabilize and achieve required current levels without interruption.
