The Kepco ABC-40-0.5 is a programmable DC power supply delivering stable, low-noise output across a 0-40V, 0-0.5A range. Built for precision bench and systems integration work, this single-output unit combines field-proven regulation with extensive protection and remote programming capabilities. Voltage mode line and load regulation hold ±0.05% or ±1 mV, while eight-hour stability reaches 0.001% in voltage mode. Peak-to-peak ripple and noise stays below 0.02%, ensuring clean power for sensitive circuits and test applications.
