The Gossen-Metrawatt Konstanter SLP 120-40 is a single-output laboratory DC power supply engineered for research, development, production, education, and service applications. It maintains stable output through constant voltage (CV) or constant current (CC) modes, delivering 120 W across a broad voltage and current range via auto-ranging capability. The unit combines precision control with multiple protection schemes and flexible interfacing options.
