The Kepco JQE100 is a 100-watt, quarter-rack linear DC power supply engineered for demanding electronic applications requiring stable, ultra-low-noise output. This unit delivers precise voltage control via a 10-turn potentiometer and adjustable current limiting, with output ripple and noise below 3 mV. The JQE100 supports three output configurations: 0–100V at 0–1A, 0–100V at 0–2.5A, or 0–100V at 0–5A. It accepts 105–125V AC or 210–250V AC mains input (selectable) at 50–65 Hz.
