The Gossen Konstanter 7KD2403-4G61 is a dual-output DC power supply designed for laboratory and industrial test environments requiring precise voltage and current regulation. It delivers two independent channels: 80V at 0.25A (20W) and 8V at 2A (16W), with minimal residual ripple and response times under 4 ms. The instrument combines local control with networked operation via addressable RS 232C serial interface (50 to 19,200 bits/sec, up to 30 devices per port) and optional IEEE 488 interface for full remote function control. Built-in overvoltage, overcurrent, and over-temperature protection with adjustable delayed shutdown (0.00 to 99.99 sec) safeguard connected loads. Dual 4-place multifunction displays show voltage, current, and power measurements in real time. Menu-driven configuration handles range limiting, protection thresholds, and digital I/O parameters. The unit stores up to 243 settings for individual or sequential recall. Analog interfaces provide monitor outputs, auxiliary power, programmable signal paths, and trigger/setpoint inputs capable of superimposing AC signals in the kHz range. Output switching via key press, RS 232C command, or trigger input enables flexible test automation.
