ply above 100% rated output. Limit your programming voltage to 10 Vdc.
Remote Programming Connections. Remote programming requires changing settings of the switch and connecting external voltages to + and - terminals of "CV" or "CC" on the rear panel. Any noise picked up on the programming leads will appear on the supply's output and may degrade regulation. To reduce noise
Notice that it is possible to operate a power supply simulta- neously in the remote sensing and the remote analog program- ming modes.
Remote Programming, Constant Voltage. Figure 6 shows the rear panel switch settings and terminal connections for remote- voltage control of output voltage. A 1 Vdc change in the remote programming voltage produces a change in output voltage (volt- age gain) as follows: E3614A: 0.8 Vdc, E3615A: 2 Vdc, E3616A: 3.5 Vdc, E3617A: 6 Vdc

MULTIPLE-SUPPLY OPERATION
Normal parallel and
NORMAL PARALLEL OPERATION
Two or more power supplies being capable of CV/CC automatic cross over operation can be connected in parallel to obtain a total output current greater than that available from one power supply. The total output current is the sum of the output currents of the individual power supplies. The output of each power supply can be set separately. The output voltage controls of one power sup- ply should be set to the desired output voltage; the other power supply should be set for a slightly higher output voltage. The sup- ply with the higher output voltage setting will deliver its constant current output, and drop its output voltage until it equals the out- put of the other supply, and the other supply will remain in con- stant voltage operation and only deliver that fraction of its rated output current which is necessary to fulfill the total load demand. Figure 8 shows the rear panel switch settings and terminal con- nections for normal parallel operation of two supplies.
