SAFETY INSTRUCTIONS
This chapter contains important safety
instructions that you must follow during
operation and storage. Read the following before
any operation to ensure your safety and to keep
the instrument in the best possible condition.
Safety Symbols
These safety symbols may appear in this manual or on the
instrument.

PSB-1000 Series User Manual
Do not dispose electronic equipment as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased.
General
Guideline
CAUTION
Do not place any heavy object on the PSB-1000.
Avoid severe impact or rough handling that
leads to damaging the PSB-1000.
Do not discharge static electricity to the PSB-
1000.
Use only mating connectors, not bare wires, for
the terminals.
Do not block the cooling fan opening.
Do not disassemble the PSB-1000 unless you are
qualified.
(Measurement categories) EN 61010-1:2010 specifies the
measurement categories and their requirements as follows. The
PSB-1000 doesn’t fall under category II, III or IV.
Measurement category IV is for measurement performed at the
source of low-voltage installation.
Measurement category III is for measurement performed in the
building installation.
Measurement category II is for measurement performed on the
circuits directly connected to the low voltage installation.
0 is for measurements performed on circuits not directly
connected to Mains.
Power Supply
WARNING
AC Input voltage range: 100Vac to 240Vac
Frequency: 47Hz-63Hz
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to
an earth ground.

SAFETY INSTRUCTIONS
Cleaning the PSB1000
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%- 85%, no condensation
Altitude: Maximum 2000m
Temperature: 0°C to 40°C
(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
and their requirements as follows. The PSB-1000 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

Disposal
Do not dispose this instrument as unsorted
municipal waste. Please use a separate collection

instrument was purchased. Please make sure
discarded electrical waste is properly recycled to
reduce environmental impact.

Power cord for the United Kingdom
When using the instrument 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:
As the colours of the wires in main leads may not correspond with
the coloured 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 either the letter E, the earth symbol
or coloured Green/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, a cable
of 0.75mm2 should be protected by a 3A or 5A fuse. Larger
conductors would normally require 13A types, depending on the
connection method used.
Any exposed wiring from a cable, plug or connection that is
engaged in a live socket is extremely hazardous. If a cable or plug is
deemed hazardous, turn off the mains power and remove the cable,
any fuses and fuse assemblies. All hazardous wiring must be
immediately destroyed and replaced in accordance to the above
standard.

Background
The PSB-1000 power supplies are regulated DC
power supplies with a high voltage and current
output. These operate in CC or CV mode
within a wide operating range limited only by
the voltage, current or power output.
The operating area of each power supply is
determined by the rated output power as well
as the voltage and current rating.
Below is a comparison of the operating areas of
each power supply.

must be taken into account before use.

PSB-1000 Series User Manual
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 mode
depends on the set current (I
SET
), the set voltage
(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
30
www.GlobalTestSupply.com
GETTING STARTED
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
.

Note
For loads that generate a transient surge voltage,
VSET must be set so that the surge voltage does
not reach the voltage limit.
For loads in which transient peak current flows,
ISET must be set so that the peak value does not
reach the current limit.
