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 E3640A 30 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.
