REMOTE CURRENT PROGRAMMING BY VOLTAGE SOURCE

Two inputs are provided for remote voltage-programming of the output current:
5 VDC full-scale and 10 VDC full-scale. The DC voltage source is connected
between Pin J1-10 (IP 5V) for 5 VDC source, or Pin J1-16 (IP 10V) for 10 VDC
source, and the return Pin J1-23 (IP RTN).

The corresponding voltage-programming coefficients for output current are
(100% rated output current) / 5 VDC, or (100% rated output current) /10 VDC,
with respect to Pin J1-23 (IP RTN). This produces transfer functions for
output current, as follows:

Iout = Vdc * (100% rated output current) / 5 VDC), with Vdc in volts, or

Iout = Vdc * (100% rated output current) / 10 VDC), with Vdc in volts.

Note:

The return Pin J1-23 (IP RTN) must be referenced directly to, or within

±3 V, of the power supply common, Pins J1-6 and J1-24. See Figure 3-14 for
connection requirements.
