146-1923 KEPCO’S HIGH VOLTAGE BHK-MG SERIES FULL HALF No matter how you rack it, we deliver the power. AN ISO 9001 COMPANY BHK-MG models are designed for a rapidly programmed voltage source control. Both digital control (local or bench or rack mount use with both where the energy storage of a conven- remote) and analog control can be front and rear output terminals. Two tional output capacitor would inhibit inputted simultaneously. operating modes are available: the output voltage’s agility. The display is an alphanumeric conventionally filtered (slow mode) for Control is either analog or digital. two-line LCD which provides both use as a fixed or slowly varied voltage Analog control is based on the idea of setting values and actual voltage and source. In this mode, the output current readings. an operational amplifier in which the capacitor provides excellent energy power supply output is programmable storage to support transient loads. A BHK-MG use a solid state FET- from zero to maximum with a 0-10V fast mode is also available. In fast mode, based high voltage output stage. signal.
