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.
Measurement category I is for measurements performed on circuits

Power Supply
WARNING
AC Input voltage: 100V/120V/220V/230V ±10%, 50/60Hz
Connect the protective grounding conductor of the AC power cord to
an earth ground, to avoid electrical shock.
Fuse
WARNING
Fuse type: 100V/120V: T6.3A/250V, 220V/230V: T3.15A/250V
Make sure the correct type of fuse is installed before power up.
To ensure fire protection, replace the fuse only with the specified type
and rating.
Disconnect the power cord before fuse replacement.
Make sure the cause of fuse blowout is fixed before fuse replacement.
Cleaning the IPS
X303 series
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 or cleaners 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: < 80%
Altitude: < 2,000m
Temperature: 0 to 40°C
(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees and
their requirements as follows. The IPS X303 series 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.

Location: Indoor
Relative Humidity: < 70%
Temperature: −10 to 70°C

Power cord for the United Kingdom
When using the IPS X303 series 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 colours 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 the letter E or by the earth symbol or coloured Green or 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, cable of 0.75mm2should be protected by a 3A or 5Afuse. Larger conductors would
normally require 13A types, depending on the connection method used.
Any moulded mains connector that requires removal /replacement must be destroyed by
removal of any fuse & fuse carrier and disposed of immediately, as a plug with bared wires is
hazardous if a engaged in live socket. Any re-wiring must be carried out in accordance with
the information detailed on this label.

OVERVIEW
This chapter describes the IPS X303 series in a nutshell, including its
main features and front / rear panel introduction. After going through the
overview, follow the Setup chapter (page 20) to properly power up and
set operation environment.
Introduction
Overview
The IPS X303 regulated DC power supply series, are light weight,
adjustable, multifunctional work stations. The IPS 2303S has two
adjustable voltage outputs. The IPS 3303S has three independent
outputs: two with adjustable voltage level and one with fixed level
selectable from 2.5V, 3.3V and 5V. The IPS 4303S has four independent
voltage outputs that are all fully adjustable. The IPS X303 series can be
used for logic circuits where various output voltage or current are
needed, and for tracking mode definition systems where plus and minus
voltages with insignificant error are required.
Independent /
Tracking Series /
Tracking Parallel
The three output modes of IPS X303 series, independent, tracking
series, and tracking parallel, can be selected through pressing the
TRACKING key on the front panel. In the independent mode, the output
voltage and current of each channel are controlled separately. The
isolation degree, from output terminal to chassis or from output terminal
to output terminal, is 300V. In the tracking modes, both the CH1 and CH2
outputs are automatically connected in series or parallel; no need to
connect output leads. In the series mode, the output voltage is doubled;
in the parallel mode, the output current is doubled.

Constant Voltage/
Constant Current
Each output channel is completely transistorized and well-regulated, and
works in constant voltage (CV) or constant current (CC) mode. Even at
the maximum output current, a fully rated, continuously adjustable output
voltage is provided. For a big load, the power supply can be used as a
CV source; while for a small load, a CC source. When in the CV mode
(independent or tracking mode), output current (overload or short circuit)
can be controlled via the front panel. When in the CC mode (independent
mode only), the maximum (ceiling) output voltage can be controlled via
the front panel. The power supply will automatically cross over from CV
to CC operation when the output current reaches the target value. The
power supply will automatically cross over from CC to CV when the
output voltage reaches the target value. For more details about CV/CC
mode operation, see page 14.
Automatic tracking
mode
The front panel display (CH1, CH2) shows the output voltage or current.
When operating in the tracking mode, the power supply will automatically
connect to the auto- tracking mode.
Dynamic load
When used in audio production lines, the power supply will provide a
continuous or dynamic load using a jumper connector (JP101/JP401)..
When the connectors are connected to the position “ON”, a stable DC
current power will be provided for audio power amplifiers.
