The Major Science MP-300V power supply is designed to meet most electrophoresis needs, running horizontal & vertical electrophoresis, and two-dimensional electrophoresis, or SDS-PAGE applications. It is recognized as the most powerful unit in its market class, running 4 systems simultaneously (and having the power to actually do it 150W). Its design provides a compact and modern stackable case. Microprocessor control offers an easy user interface. The user has control of constant voltage output as well as constant current output. Pause/resume functions and a timer with alarm allow run capability during timed or continuous operation. The safety devices include no load detection, leakage detection, sudden load change detection, over temperature protection, and over load detection.
