Remote Resistor Programming, Constant Current

Figure 8

Set the CC switch down on the rear panel, and all others up. Iout = A x [VREF x {R/(R + R2 + 100)}]

Where Iout is the power supply output current.

A is the gain factor and the values of each model are as below. VREF is between 10.11 V and 11.40 V.

R = (92800 x R1)/(92800 + R1)

R1 + R2>> 40 kohm

Model	A

E3614A	0.6

E3515A	0.3

E3616A	0.17

E3617A	0.1
