Highlights

More Voltage and Current Combinations With Dual Range

The E3640A Series bench power supply gives you outputs from 30 W to 100 W of power along with dual range flexibility. Each output has a low and high voltage range. The low voltage range allows the power supply to output more current. The series also has models with one and two outputs – tracking is turned on or off to allow the two outputs to operate independently or work as a pair.

  • Low output noise with ripple and noise < 500 µVrms
  • Stable output, load regulation < 0.01%
  • Meter accuracy better than 0.05%
  • Store and recall up to five different operating states
  • Highly visible vacuum fluorescent display
  • One or two channels
  • Connectivity: RS232 and GPIB
