Auxiliary Power; Out 3 Variable Dc Auxiliary Supply - SMC Networks PTE-100-C PRO User Manual

AUXILIARY POWER

Auxiliary power is commonly intended to energize the devices under test, or
to polarize electrical reference components, rather than for actual injection
of test magnitudes. Auxiliary electronics are not dimensioned nor calculated
for big power values. The PTE-100-C PRO features two auxiliary voltage
outputs: one variable 0-250 VDC (Out 3) and one fixed 110 VAC voltage
(Out 4).
The most important differences between these outputs and the test outputs
(current taps, voltage output 1, and voltage output 2) are:
Out 3 and Out 4 are completely independent from each other and

from the power current and voltage Out 1 and Out 2 taps.
Out 3 and Out 4 are not automatically shut off during the test pro-

cedure.
Timer operation is not directly affected by these auxiliary outputs.

Out 3 variable DC auxiliary supply

Out 3 is a variable 0-250 V stabilized DC supply. This means that its output
level greatly withstands fluctuations at the mains supply and at the power
outputs. Out 3 is protected by a dedicated fuse and an electronic protection
against short circuits and overloads. Before connecting any device to Out 3,
do the following:
1. Press
2. Turn the small regulation knob all the way counter clock-
