3.4.2 REMOTE CURRENT PROGRAMMING USING A 0-5 OR 0-10 VDC
VOLTAGE SOURCE
A DC voltage source for remote current programming is connected
between J1-10 (IP 5V) or J1-16 (IP 10V) and the return terminal
J1-23 (IP RTN).
Note : The return terminal J1-23 (IP RTN) must be referenced directly to
or within ±3V of the power supply common, J1-24.
The voltage coefficient for 5V remote current programming is 50 millivolts
= 1% of rated output, i.e., for a 300 amp model, each 50 millivolts of
programming voltage equals 3 amps of output current.
The voltage coefficient for 10V remote current programming is 100
millivolts = 1% of rated output, i.e., for a 300 amp model, each 100
millivolts of programming voltage equals 3 amps of output current. See
Figure 3-10 for connection requirements.
