Safety Guidelines
General
Guideline
CAUTION
Do not place any heavy object on the unit.
Avoid severe impact or rough handling that
leads to damaging the unit.
Do not discharge static electricity to the unit.
Do not block the cooling fan opening.
Do not perform measurements on circuits that
are directly connected to mains power.
Do not disassemble the PSB unless you are
qualified.
(Measurement categories) EN 61010-1:2010 specifies the
measurement categories and their requirements as follows. The
PSB-2000 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.
O is for measurements performed on circuits not directly
connected to Mains.
Power Supply
WARNING
AC Input voltage range: 100Vac to 240Vac,
1300VA Max
Frequency: 50Hz/60Hz
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to
an earth ground.

SAFETY INSTRUCTIONS

Cleaning the
power supply
Disconnect the power cord before cleaning the
oscilloscope.
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid
into the oscilloscope.
Do not use chemicals 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: 30% to 80% (no dew or
condensation)
Altitude: < 2000m
Temperature: 0°C to 40°C
(Pollution Degree) EN 61010-1:2010 specifies pollution degrees
and their requirements as follows. The PSB 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
Relative Humidity: 30% to 70% (no dew or
conensation)
Temperature: -20°C to 70°C

Power cord for the United Kingdom
When using the power supply 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
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 0.75mm2should 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.

GETTING STARTED
The PSB series are variable output, high-
performance, regulated, switching DC power
supplies. They incorporate a high-frequency
current suppression circuit and accept input
voltages rated from AC100V to 240V without the
need to switch inputs. The offer a wide voltage
and current range within their maximum rated
power envelope. They also have a variable
constant power function. They have standard
features such as voltage and current settings, an
output on/off switch, monitor outputs and other
functions via external connectors. The chasis is
smaller overall than traditional power supplies to
reduce the total work area. The dual channel
model and the booster unit extend the series to
cover a wider range of applications. The PSB series
are also able to execute sequence programs that
are written using the optional interface boards.
The optional interface boards also allow you to
control the PSB series remotely from a PC using
GPIB, RS232C or USB.

Main Features
Multi-Range
Output
Capable of a wide-range of voltage and current
settings within the rated power envelope.
Constant-Power
Control
Provides constant-power (CP) control in addition to
constant-voltage (CV) and constant-current (CC)
controls.
Power Factor
Correction Circuit
A built-in power factor correction circuit ensures
compatibility to a wide AC input voltage range from
AC100V to 240V without the need to use a switch. It
also suppresses harmonic current.
Rotatable Front
Panel Controls
The front panel can be rotated by 90 degrees to allow
the unit to be operated horizontally or vertically.
Output Off Timer
Function
Turns the output off automatically after a preset
amount of time has elapsed. This can be used to
prevent the output from being left on inadvertently or
to prevent over-charging.
Sequence (SEQ)
Function
The Sequence function executes data read from a PC
through one of the optional interface boards (PSB-
001 and PSB-002). There are two operation modes for
the sequence function: Manual mode (for step by
step execution) and automatic mode (for automatic
execution of up to 99 steps and 999 cycles).
Protective
Functions
The power supplies have a number of protection
functions. OVP, OCP and OHP. OVP and OCP
protection can be set on the front panel.
Preset Functions
(Three Settings)
Pressing a preset key directly selects a preset setting,
which is set in advance.

Single Unit
Control of
Parallel/Series
Operation
The PSB-L series uses a single power supply unit
(acting as the master unit) to control all connected
slave units for series or parallel operation. In parallel,
up to 4 units can be controlled (including the master)
to increase the total power. In series, a maximum of 2
units (including the master) can be used.
External Control
Function
The external control function allows external voltage
and restistance-based control, voltage and current
monitoring, output on/off control, alarm output and
CV/CC status output.
Interface Boards
There are two optional interface boards for remote
control.
PSB-001: GPIB and local bus board.
PSB-002: RS-232C, USB and local bus board.
Note also that one of these options must be used to
program sequences for the PSB-L series. See page 86
for further details.
Dual Channel
Model
(PSB-2400L2)
Equipped with two 400W output channels for a
wide variety of applications.
Delay (DLY)
Function:
(PSB-2400L2
Only)
The delay function introduces a switching delay
between channel 1 and 2. The delay function can set
a rising delay (the time to turn on) and a falling delay
(the time to turn off).
Tracking
Function:
(PSB-2400L2
Only)
The channel 2 setting is made equal to that of
channel 1 when the tracking function is activated.
Thereafter, both channels change synchronously.
