The Kepco KLP75-33 is a 1200 W programmable DC power supply engineered for laboratory and system integration, delivering 0–75 V DC across a hyperbolic power envelope that maximizes flexibility within its 1200 W constant power limit. The switch-mode topology achieves up to 84% efficiency while maintaining a compact 1U rack-mount form factor (1.75 inches high) with front-to-back airflow cooling that permits zero-clearance stacking. Universal AC input (90–265 VAC, 45–440 Hz) with active power factor correction accommodates global power infrastructure. Digital control via GPIB (IEEE 488.2), RS-232, and optional LAN/LXI interfaces enables remote programming and monitoring using SCPI command sets. Stud-style output terminals, front-panel rotary encoders, and dual 4-digit displays provide intuitive local operation alongside full automation capability.
