Kepco JQE150-7M

The Kepco JQE150-7M is a 1000-watt DC power supply housed in a full-rack form factor, engineered for laboratory research, industrial automation, and precision test applications. Built on a linear, full-dissipation series-regulator architecture with integrated circuit operational amplifier control, it delivers exceptionally low noise and ripple output. The unit combines front-panel precision with flexible external control options, supporting both analog and digital command interfaces.
