The Gossen Konstanter is a laboratory DC power supply delivering three independently controllable outputs: dual 18V/1A channels and one 8V/2A channel. Built for electronic testing and system applications, it combines manual and remote control with floating, isolated outputs classified as Safety Extra-Low Voltage (SELV) per VDE/IEC standards. The unit integrates dual 4-place digital LED displays, programmable logic inputs/outputs, and optional IEEE488 or RS232C interfaces for computer automation. Front-panel control via rotary knobs with adjustable resolution enables precise voltage and current management, while protective features include overvoltage protection, delayed overcurrent shutdown, and configurable range limiting. Master-slave operation is possible through the analog interface for multi-unit synchronization.
