Analogue Out Control Voltages
Analogue Out control voltages V
out
and I
out
are generated from the actual internal control voltages,
for which the active source can be the front panel controls, or the remote analogue inputs CV and
CC. V
out
and I
out
are scaled such that 0 to 100% of the maximum output voltage and current
generate 0V to 5V at the rear panel V
out
and I
out
terminals with respect to COM. I
out
always
corresponds to the set current, whether the output is on or off, but V
out
goes to 0V when the output
is off.
Warning! COM is referenced to the output control circuit and will be within ~1V of the
positive output potential. V
OUT
and I
OUT
are always present on the terminals.
Parallel Operation in Master-Slave Configuration
Parallel operation in Master-Slave configuration permits higher output currents to be realised with
equal current sharing between units and control of both voltage and current from a single unit. The
diagram shows 3 units connected in parallel. For equal current sharing each unit must be
independently connected to the load with pairs of wires of equal gauge and length to ensure equal
voltage drops. Connect the V
out
, I
out
and COM of the master to the CV, CC and RTN inputs of the
slaves (set CV and CC switches to Remote) as shown.
Parallel Operation in Master-Slave Configuration
Notes:
1. Units can be wired for CV (constant
voltage), CC (constant current) or both
(both shown). Set CV and/or CC
switches of slaves to Remote.
2. Connect outputs in parallel using equal
length wires to the load.
3. If remote sensing is required use only
remote sense from the master to the
load.
4. For constant current operation set the
required voltage overhead on the
master.
