Kepco JQE 55-10

The Kepco JQE 55-10 is a single-output programmable DC power supply delivering 0-55 Vdc at 0-10 Adc with 550 W maximum output. Engineered for precision and stability, it combines tight load and line regulation with low ripple and noise, making it ideal for laboratory benches, production testing, and automated system integration. Voltage and current control via multi-turn potentiometer or external analog input (0-5 V or 0-10 V) enable seamless integration into test frameworks. Remote sensing compensates up to 0.5 V per lead, while response time under 50 microseconds to 50% load steps ensures transient performance. Operating across 0°C to 65°C with temperature coefficients of 15 ppm/°C (voltage) and 25 ppm/°C (current), the unit maintains output stability after warm-up drift below 0.01% of rated output. Selectable input voltage (105–125 V ac or 210–250 V ac) at 45–63 Hz accommodates global installations. Analog programming resolution reaches 0.05% of full scale via external voltage control, with dedicated voltage and current monitoring outputs (0-5 Vdc or 0-10 Vdc) for feedback and data logging. Ripple and noise remain below 1 mVrms and 5 mVpeak-to-peak respectively. Load regulation holds to 0.01% (voltage) and 0.02% (current); line regulation to 0.005% (voltage) and 0.01% (current). Typical efficiency of 75% at full load and power factor exceeding 0.8 minimize thermal dissipation in confined spaces.
