Allows two different groups of students to perform experiments at the same time from the same power supply. Both
positive and negative outputs of this solid-state power supply can be operated independently of each other or in series with one another.
Input: 120-V AC, 50/60 Hz
Output 1: Variable, 0 to 9-V DC positive @ 0.5A
Output 2: Variable, 0 to 9-V DC negative @0.5A
Output 3: Variable 0 to 18-V DC @ 0.5A
Ripple: 0.25 V.P.P. at all output voltages with a 0.5 A load
