The Kepco JQE25-4M is a 100-watt DC power supply engineered for benchtop and system integration applications requiring precise voltage regulation with minimal noise. This quarter-rack supply delivers 0–25 V adjustable output at 0–4 A, featuring ultra-low output ripple below 3 mV and exceptional control resolution via a 10-turn voltage potentiometer. Dual control modes—analog programming by external resistance (1000 Ω/Volt) or voltage (0–1 mA)—enable flexible integration into automated test systems. The front panel current limiter adjusts from 10% to 105% of maximum output current, while remote programming supports external voltage or resistance control. Output impedance is exceptionally low: 300 µΩ series resistance and 1 µH series inductance in voltage mode; 125 kΩ shunt resistance and 700 µF shunt capacitance in current mode.
