Gossen Konstanter 7KD2402-3XD3 DC Power Supply 2X 18V 1A

The Gossen Konstanter 7KD2402-3XD3 is a dual-output DC power supply engineered for laboratory, development, and test bench applications. It delivers two independent 18V DC outputs, each rated for 1A, with constant voltage and constant current regulation modes. The unit features overvoltage and overcurrent protection with adjustable delayed shutdown, dual 4-place multifunction displays for voltage/current/power readout, and manual adjustment via rotary pulse generators.

Load regulation and transient response are optimized for load-independent performance, with response times typically under 1 ms. Protection circuits and regulation accuracy are hallmarks of the Konstanter series, making this supply suitable for powering sensitive electronic systems requiring stable, independent dual-rail outputs.
