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.

PPX Series User Manual
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.
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
20
GETTING STARTED
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 (I
SET
) 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 (V
SET
), the
load resistance (RL) and the critical resistance
(RC). The critical resistance is determined by
V
SET/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 V
SET
voltage
but the current will be less than I
SET
. If the load
resistance is reduced to the point that the
current output reaches the I
SET
level, the power
supply switches to CC mode.
CC and CV Mode
21
PPX Series User Manual
Conversely the power supply will operate in
CC mode when the load resistance is less than
the critical resistance. In CC mode the current
output is equal to I
SET
and the voltage output is
less than V
SET
.

Theory
The PPX has selectable slew rates for CC and
CV mode. This gives the PPX power supply the
ability to limit the current/voltage draw of the
power supply. Slew rate settings are divided
into High Speed Priority and Slew Rate
Priority. High speed priority mode will use the
fastest slew rate for the instrument. Slew Rate
Priority mode allows for user adjustable slew
rates for CC or CV mode. The rising and falling
slew rate can be set independently.

Background
The PPX DC power supplies employ a bleed
resistor in parallel with the output terminals.
PPX
Load
Bleed
resistor
Bleed resistors are designed to dissipate the
power from the power supply filter capacitors
when power is turned off and the load is
disconnected. Without a bleed resistor, power
may remain charged on the filter capacitors for
some time and be potentially hazardous.
In addition, bleed resistors also allow for
smoother voltage regulation of the power
supply as the bleed resistor acts as a minimum
voltage load.
The bleed resistance can be turned on or off
using the configuration settings.
Bleeder Control
23
PPX Series User Manual
Note
By default the bleed resistance is on. For battery
charging applications, be sure to turn the bleed
resistance off as the bleed resistor can discharge
the connected battery when the unit is off.
OVP
Over voltage protection (OVP) prevents a high
voltage from damaging the load. This alarm
can be set by the user.
OCP
Over current protection prevents high current
from damaging the load. This alarm can be set
by the user.
UVL
Under voltage limit. This function sets a
minimum voltage setting level for the output.
It can be set by the user.
OTP
Over temperature protection protect the
instrument from overheating
AC ALARM
When AC input voltage or frequency is
abnormal or beyond the AC power range
under operation, the alarm will be generated.
SENSE ALARM
This alarm function is activated when real
output voltage is larger than sense output
voltage.
Alarm output
Alarms are output via the analog control
connector. The alarm output is an isolated
open-collector photo coupler output.
Alarms
The PPX power supplies have a number of protection features.
When one of the protection alarms is set, the ALM icon on the
display will be lit. For details on how to set the protection modes,
please see page 47.
24
GETTING STARTED
Inrush current
When the power supply switch is first turned
on, an inrush current is generated. Ensure there
is enough power available for the power
supply when first turned on, especially if a
number of units are turned on at the same
time.
Caution
Cycling the power on and off quickly can cause the
inrush current limiting circuit to fail as well as
reduce the working life of the input fuse and power
switch.
Pulsed or Peaked
loads
When the load has current peaks or is pulsed, it
is possible for the maximum current to exceed
the mean current value. The PPX power supply
ammeter only indicates mean current values,
which means for pulsed current loads, the
actual current can exceed the indicated value.
For pulsed loads, the current limit must be
increased, or a power supply with a greater
capacity must be chosen. As shown below, a
pulsed load may exceed the current limit and
the indicated current on the power supply
ammeter.
Considerations
The following situations should be taken into consideration when
using the power supply.

Reverse Current:
Regenerative load
When the power supply is connected to a
regenerative load such as a transformer or
inverter, reverse current will feed back to the
power supply. The PPX power supply cannot
absorb reverse current. For loads that create
reverse current, connect a resistor in parallel
(dummy load) to the power supply to bypass
the reverse current. To calculate the resistance
for the dummy resistor, RD, first determine the
maximum reverse current, IR, and determine
what the output voltage, EO, will be.

CAUTION
Ensure the reverse withstand voltage of the diode

Ensure the diode is able to withstand the heat
generated in the following scenarios.
When the diode is used to limit reverse voltage,
remote sensing cannot be used.

OPERATION
Background
The OVP level and OCP level has a selectable
range that is based on the output voltage and
output current, respectively. The OVP and OCP
level is set to the highest level by default. The
actual selectable OVP and OCP range depends
on the PPX model.
When one of the protection measures are on,
the type of alarm message will be shown on
display. Press Shift + PROT key to clear any
protection alarm messages that have been
tripped. By default, the output will turn off
when the OVP or OCP protection levels are
tripped.
The UVL will prevent you from setting a
voltage that is less than the UVL setting. The
UVL setting range is from 0% ~ 105% of the
rated output voltage.
Before setting the protection settings:
• Ensure the load is not connected.
• Ensure the output is turned off.
Note
You can enter the PROT setting to apply limits to
the voltage and current settings, respectively. You
can set limitations so that the values do not exceed
the set OVP and the set OCP level, and so that the
values are not lower than the set UVL trip point. By
using this feature, you can avoid turning the output
off by mistakenly setting the voltage or current to a
value that exceeds the set OVP or OCP level or to a
value that is lower than the set UVL trip point.
If you have selected to limit the voltage setting, you
Setting OVP/OCP/UVL Levels

will no longer be able to set the output voltage to a
value that is above about 95% of the OVP trip point
or to a value that is lower than the UVL trip point. If
you have selected to limit the current setting, you
will no longer be able to set the output current to a
value that is above about 95% of the OCP trip point.
Lastly, the Delay time setting for OCP delays trigger

WARNING
Ensure the output is off before handling the
remote sense connector.
Use sense cables with a voltage rating exceeding
the isolation voltage of the power supply.
Never connect sensing cables when the output is
on. Electric shock or damage to the power supply
could result.
Output terminal
Connector
Overview
When using the remote sensing, make sure the
wires that are used follow the following guidelines:
Wire gauge:
AWG 20 to AWG 14
Strip length:
6.5mm // 0.26 in.
+S: +Sense terminal
-S: -Sense terminal
Note
Be sure to remove the Sense joining cables so the
units are not using local sensing.
Remote Sensing
Remote sense is used to compensate for the voltage drop seen
across load cables due to the resistance inherent in the load cables.
The remote sense terminals are connected to the load terminals to
determine the voltage drop across the load cables.
Remote sense can compensate up to 1 volt for PPX1005/2002/2005/3601/3603 and 3 volts for PPX-10H01
(compensation voltage). Load cables should be chosen with a
voltage drop less than the compensation voltage.
