SAFETY INSTRUCTIONS
7
To ensure fire protection, replace the fuse only
with the specified type and rating.
Disconnect the power cord before fuse
replacement.
Make sure the cause of fuse blowout is fixed
before fuse replacement.
Cleaning the
device
Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid.
Do not use chemicals or cleaners containing
harsh products such as benzene, toluene,
xylene, and acetone.
Operation
Environment
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (note below)
Relative Humidity: < 80%
Altitude: < 2000m
Temperature: 0°C to 40°C
(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
and their requirements as follows. The T3PSX3200 series falls under
degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of dielectric
strength or surface resistivity”.
Pollution degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence.
Pollution degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity caused
by condensation must be expected.
Pollution degree 3: Conductive pollution occurs, or dry, non-
conductive pollution occurs which becomes conductive due to
condensation which is expected. In such conditions, equipment
is normally protected against exposure to direct sunlight,
precipitation, and full wind pressure, but neither temperature
nor humidity is controlled.

Power cord for the United Kingdom
When using the T3PSX3200 series in the United Kingdom, make
sure the power cord meets the following safety instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the
following code:
Green/ Yellow:
Earth
Blue:
Neutral
Brown:
Live (Phase)
As the colours of the wires in main leads may not correspond with the colours
marking identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be connected to the Earth
terminal marked with the letter E or by the earth symbol or coloured Green or
Green & Yellow.
The wire which is coloured Blue must be connected to the terminal which is
marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal marked
with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or contact the
supplier.
This cable/appliance should be protected by a suitably rated and approved
HBC mains fuse: refer to the rating information on the equipment and/or user
instructions for details. As a guide, cable of 0.75mm2should be protected by a
3A or 5A fuse. Larger conductors would normally require 13A types, depending
on the connection method used.
Any moulded mains connector that requires removal /replacement must be
destroyed by removal of any fuse & fuse carrier and disposed of immediately, as
a plug with bared wires is hazardous if a engaged in live socket. Any re-wiring
must be carried out in accordance with the information detailed on this label.

This chapter describes the T3PSX3200 series,
including its main features and front/ rear panel
introduction. After going through the overview,
follow the Setup chapter (page 25) to properly

Introduction
Overview
The T3PSX3200 series regulated DC power supply
series are light weight, adjustable, multifunctional
power supplies. The T3PS13206 has a single
independent adjustable voltage output (Coarse
and fine). The remote voltage compensation
function is activated for large changes in current
output. The T3PS23203 has 2 independent
adjustable voltage outputs. The T3PS33203 has
three independent outputs: two with adjustable
voltage levels and one with fixed 5V level. The
T3PS43203 has four independent voltage outputs
that are all fully adjustable.
Independent /
Series Tracking /
Parallel Tracking
The three output modes of T3PS23203/ 33203/
43203, independent, series tracking and parallel
tracking can be selected through pressing the
TRACKING key on the front panel. In the
independent mode, the output voltage and current
of each channel are controlled separately. In the
tracking modes, both the CH1 and CH2 outputs
are automatically connected in series or parallel.
CH1 is master and CH2 is slave. In the series
mode, the output voltage is doubled; in the
parallel mode, the output current is doubled. The
isolation, from output terminal to chassis or from
output terminal to output terminal, is 500V

T3PSX3200 Series User Manual
12
Constant Voltage/
Constant Current
Each output channel works in constant voltage
(CV) or constant current (CC) mode. Even at the
maximum output current, a fully rated,
continuously adjustable output voltage is
provided. For a big load, the power supply can be
used as a CV source; while for a small load, a CC
source. When in the CV mode (independent or
tracking mode), output current (overload or short
circuit) can be controlled via the front panel. When
in the CC mode (independent mode only), the
maximum (ceiling) output voltage can be
controlled via the front panel. The power supply
will automatically cross over from CV to CC
operation when the output current reaches the
target value. The power supply will automatically
cross over from CC to CV when the output voltage
reaches the target value. For more details about
CV/CC mode operation, see page 24.
Automatic
tracking mode
The front panel display (CH1, CH2) shows the
output voltage or current. When operating in the
tracking mode, the power supply will
automatically connect to the auto- tracking mode.
For more details about CH1/CH2 Series Tracking
Mode, see page 42

OVERVIEW

Auxiliary Rectifier
The auxiliary rectifiers D120~ D123 provide bias
voltage filtered by the capacitors C120 and C121,
for the pre-regulators U150 and U151. They
provide a regulated voltage for other modules.
Main Rectifier
The main rectifier is a full wave bridge rectifier. It
provides the power after the rectifier is filtered by
the capacitor C101, and then regulated via a
series-wound regulator, which is finally delivered
to the output terminal.
Current Limiter
U151 is a comparator amplifier which compares
the reference voltage to the feedback voltage, and
then delivers it to Q151, which then calibrates the
output voltage.
Overvoltage
U131 is a comparator which activates when the
unit is overloaded and it controls the output of
U132 to turn off the output and inform the user.
