The Gossen Konstanter 80V 4A is a programmable DC power supply delivering regulated voltage and current outputs for laboratory and industrial testing applications. It operates as both a source and sink across a 2-quadrant output area, with floating isolated output classified as Safety Extra-Low Voltage (SELV). The unit combines fast transient response, load-independent regulation, and intelligent protection schemes with analog and serial interfaces for manual or computer-controlled operation.
