Gossen-Metrawatt Konstanter SlP 240-80 Stabilized DC Power Supply

The Gossen-Metrawatt Konstanter SlP 240-80 is a single-output stabilized DC power supply delivering 240 W nominal power for research, development, production, training, and service applications. Precise voltage and current adjustment via ten-turn potentiometers with settable limit ranges prevents unintended changes. The unit operates in constant voltage (CV) or constant current (CC) mode, with status indication via LEDs and open-collector signal outputs.

Remote sensing, analog control interfaces, and digital trigger input enable flexible system integration. Over-temperature protection and comprehensive safety monitoring safeguard connected equipment.

Compatibility & Integration Complies with IEC 61010-1:1990 + A1:1992, DIN EN 61010-1:1993, VDE 0411-1:1994, VDE 0160:1988 + A1:1989 Klasse W1, and EN 60950:1992. Open-collector signal outputs integrate with standard digital logic and relay control systems. Analog 0–10 V interface suits both direct instrumentation and data acquisition systems. Proper fuse selection per technical data or serial plate marking is mandatory.
