  • Linear Bench Power Supplies Local Control, Ultra Low Ripple/Noise

    Series MSK - Kepco, Inc.

    Kepco's MSK linear power supplies provide a selection of five models, offering 100 Watts of stable benchtop power. They use a high gain linear (series pass) stabilizer circuit for ultra low noise and low ripple output, good stability, and accurate resettability, and they are MIL-STD-461 compliant.MSK's "Preview" switch (d-c on-off) allows voltage and current to be pre-set with the digital meters displaying the set values. At "d-c off," no voltage is applied to the output terminals and no load current needs to be drawn to set the current limit. At "d-c on," the set voltage is applied to the output terminals, the appropriate mode indicator illuminates and the meters indicate actual voltage and current.

  • MEGA-POLE® Series

    MEGA-POLE™ - Pole/Zero

    The MEGA-POLE filter series covers the standard frequency bands within the 30 to 450 MHz range. This new filter series provides excellent selectivity while maintaining very low insertion loss.
