Safety Guidelines
General
Guideline
CAUTION
Do not place any heavy object on the T3PS.
Avoid severe impact or rough handling that
leads to damaging the T3PS.
Do not discharge static electricity to the T3PS.
Use only mating connectors, not bare wires, for
the terminals.
Do not disassemble the T3PS unless you are
qualified.
Power Supply
CAUTION
WARNING
AC Input Voltage:
100Vac/120Vac/220Vac/240Vac, 50Hz/60Hz,
single phase
Frequency: 47Hz to 63Hz
Before connecting the power plug to an AC line
outlet, make sure the voltage selector switches
of the bottom panel in the correct position.
Disconnect power cord and test leads before
replacing fuse.
The fuse specification is as following:

LINE
250V
T3.15A
110V~
120V~
250V
T1.6A

Cleaning the
T3PS
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 containing harsh material
such as benzene, toluene, xylene, and acetone.
Operation
Environment
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
Relative Humidity: 20%~ 80%(no condensation)
Altitude: < 2000m
Temperature: 0°C to 40°C
(Pollution Degree) EN61010-1:2010 specifies the pollution degrees
and their requirements as follows. The T3PS 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.
Storage
environment
Location: Indoor
Temperature: -20°C to 70°C
Relative Humidity: 20 to 85%(no condensation)
Disposal
Do not dispose this instrument as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased. Please make sure
discarded electrical waste is properly recycled to
reduce environmental impact.

Theory of Operation
The theory of operation chapter describes the basic principles of
operation, protection modes and important considerations that
must be taken into account before use.
Operating Description
Background
The T3PS power supplies are regulated DC power
supplies with a stable voltage and current output.
These operate within a switch automatically
between constant voltage and constant current
according to changes in the load.
Note
Suitable supply cord set for use with the equipment:
Mains plug: shall be national approval
Mains connector: C13 type
Cable:
1. Length of power supply cord: less than 3m
2. Cross-section of conductors: at least 0.75mm2
3. Cord type: shall meet the requirements of IEC
60227 or IEC 60245 (e.g.: H05VV-F, H05RN-F)
Caution
If the equipment is used in a manner not specified by
the manufacturer, the protection provided by the
equipment may be impaired.

T3PS Series User Manual

CC and CV Mode
CC and CV mode
Description
When the power supply is operating in constant
current mode (CC) a constant current will be
supplied to the load. When in constant current
mode the voltage output can vary, whilst the
current remains constant. When the load
resistance increases to the point where the set
current limit (ISET) can no longer be sustained the
power supply switches to CV mode. The point
where the power supply switches modes is the
crossover point.
When the power supply is operating in CV mode,
a constant voltage will be supplied to the load,
whilst the current will vary as the load varies. At
the point that the load resistance is too low to
maintain a constant voltage, the power supply
will switch to CC mode and maintain the set
current limit.
The conditions that determine whether the power
supply operates in CC or CV (VSET), the load
resistance (RL) and the critical resistance (RC). The
critical resistance is determined by VSET/ISET. The
power supply will operate in CV mode when the
load resistance is greater than the critical
resistance. This means that the voltage output
will be equal to the VSET voltage but the current
will be less than ISET. If the load resistance is
reduced to the point that the current output
reaches the ISET level, the power supply switches
to CC mode.
