Multiple Loads

If you are using local sensing and are connecting mu ltiple loads to

one output, connect each load to the output termi nals using separate

connecting wires as shown in the following figure.

This minimizes mutual coupling effects and takes full advantage of

the power system's low output impedance. Keep each pair of wires as

short as possible and twist or bundle them to re duce lead inductance

and noise pickup.

If load considerations require the use of distribution termi nals that

are located away from the instrument, connect the output terminals

to the remote distribution terminals by a pai r of twisted or bundled

wires. Connect each load to the distribution terminals separately.

Remote voltage sensing is recommended under these circumstances.

Sense either at the remote distribution terminal s or, if one load is

more sensitive than the others, directly at the critical load.

Response Time with an External Capacitor

When programming with an external capacitor, vo ltage response time

may be longer than that specified in Appendix A. Use the following

formula to estimate the additional response time for up

programming:

Response Time = (Added Output Capacitor)X(Change in Vout)

Current Limit Setting

Note that programming into an external outpu t capacitor may cause

the power system to briefly enter constant curren t or constant power

operating mode, which adds additional time to t he estimation.

Positive and Negative Voltages

Either positive or negative voltages can be obtained fr om the output

by grounding (or "commoning") one of the output terminals. Always

use two wires to connect the load to the output regardless of where

or how the system is grounded. The instrument can be operated with

any output terminal ± 240 VDC including output voltage from ground.
