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.
The E3642A 50 W bench power supply has dual-range flexibility with a low and high voltage range. The low voltage range allows the power supply to output more current. The E3640 Series has models with single and dual outputs—automate tests with GPIB or RS232.
