Programmable Power Supplies
Models 1770, 1775, 1780
  • The ideal blend of programmability, in-the-case calibration and selectable voltage and current output range make these new power supplies the best cost/performance value on the market.
  Three Versatile Models

  1770 - Dual Range, 35Volts to 6A $1050
  1775 - Dual Output, 35Volts at 2A
  1780 - Dual Output, 18Volts at 4A
  Standard GPIB IEEE 488.1 Interface
  High Reliability - 50k Hours MTBF
B&K Features/ User Benefits:

Standard GPIB Interface/ Greater flexibility interfacing with a number of third party GPIB cards, computers and controllers.

Parallel and Series Operation/ (1775 & 1780) Increases useable voltage and current capabilities for a wider variety of applications. One power supply satisfies a greater number of applications.

Front Panel Keypad/ Easy entry to set voltage, current, overvoltage and over-current.

Remote Sensing/ Maintains set voltage regardless of lead loss.

Backlit LCD Display/ Vital output information, voltage, current and operating mode.

True RMS Reading Metering/ Reliable means of comparing dissimilar waveforms.

50k MTBF/ High reliability with no downtime.
