The Kepco JQE15 is a precision, linear, series-regulated DC power supply engineered for laboratory, industrial, and system integration applications requiring stable voltage output and short-circuit protection. Available in 1/4-rack, 1/2-rack, and full-rack configurations with output power ratings from 45 W to 500 W, the JQE15 delivers 0–15 V DC across current ranges of 6 A to 25 A depending on model selection. All-silicon design with conservatively rated components ensures reliable operation across single-phase AC input of 105–125 V or 210–250 V at 47–65 Hz with approximately 0.9 power factor.
