Output rating
The rated output voltage and current specifications in
Chapter 7 apply at the output terminals of the power
supply. With remote sensing, any voltage dropped in the
load leads must be added to the load voltage to calculate the
maximum output voltage. The performance specifications are
not guaranteed when the maximum output voltage is
exceeded. If the excessive demand on the power supply
forces the power supply to lose regulation, the Unreg
annunciator will turn on to indicate that the output is
unregulated.
Output noise
Any noise picked up on the sense leads also appears at the
output of the power supply and may adversely affect the
voltage load regulation. Twist the sense leads to minimize
external noise pickup and run them parallel and close to the
load leads. In noisy environments, it may be necessary to
shield the sense leads. Ground the shield at the power
supply end only. Do not use the shield as one of the sense
conductors.
Multiple loads
When connecting multiple loads to the power supply, each
load should be connected to the output terminals using
separate connecting wires. This minimizes mutual coupling
effects between loads and takes full advantage of the low
output impedance of the power supply. Each pair of wires
should be as short as possible and twisted or bundled to
reduce lead inductance and noise pick- up. If a shield is
used, connect one end to the power supply ground terminal
and leave the other end disconnected.
If cabling considerations require the use of distribution
terminals that are located remotely from the power supply,
connect output terminals to the distribution terminals by a
pair of twisted or shielded wires. Connect each load to the
distribution terminals separately.
