Kepco MSK 40-2.5M

The Kepco MSK 40-2.5M is a 100-watt single-output DC power supply engineered for laboratory and maintenance testing applications requiring precise voltage and current regulation. The unit delivers 0–40V DC at 0–2.5A DC with exceptionally tight load and source regulation, making it suitable for demanding bench-level work. It employs a high-gain linear series-pass stabilizer circuit with automatic crossover between voltage and current modes, coupled with integrated overvoltage protection via SCR latching circuit. The Preview switch enables offline presetting of output parameters on digital meters before load connection—a critical safety feature for test setup workflows.
