Safety Guidelines
General
Guideline
CAUTION
Do not place any heavy object on the PPX.
Avoid severe impact or rough handling that
leads to damaging the PPX.
Do not discharge static electricity to the PPX.
Use only mating connectors, not bare wires, for
the terminals.
Do not disassemble the PPX 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:
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to an
earth ground.
Cleaning the
PPX
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 PPX 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 PPX 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.
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.

PPX Series Programming 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.
