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.
OVERVIEW
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
9
IPS X303 Series Instruction Manual
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.

Rectifier
The auxiliary rectifiers D1011 to D1014 provide bias voltage filtered by
the capacitors C102 and C103, for the pre-regulators U101 and U102.
They provide a regulated voltage for other modules.
Main Rectifier
The main rectifier is a full wave bridge rectifier. It provides the power
after the rectifier is filtered by the capacitor C101, and then regulated via
a series-wound regulator, which is finally delivered to the output terminal.
Principle of Operation
12
OVERVIEW
Current Limiter
U104 acts as a current limiter. When the current is over predetermined
rating, U104 is activated and decreases the current. U208 provides a
reference voltage. U206 is the inverter amplifier. U103 is a comparator
amplifier which compares reference voltage and feedback voltage, and
then delivers to Q102, which then calibrates the output voltage.
Overload
When the unit is overloaded, Q107 activates to control the current
magnitude of Q102, to limit the output current. The relay control circuit
controls the power dissipation in the series-wound regulated circuit.
13
IPS X303 Series Instruction Manual
Background
The IPS X303 series automatically switches between constant voltage
mode (CV) and constant current mode (CC), according to load condition.
CV mode
When the current level is smaller than the output setting, the IPS X303
series operates in Constant Voltage mode. The indicator on the front
panel turns green (C.V.) The Voltage level is kept at the setting and the
Current level fluctuates according to the load condition until it reaches
the output current setting.
CC mode
When the current level reaches the output setting, the IPS X303 series
starts operating in Constant Current mode. The indicator on the front
panel turns red (C.C.) The Current level is kept at the setting but the
Voltage level becomes lower than the setting, in order to suppress the
output power level from overload. When the current level becomes lower
than the setting, the IPS X303 series goes back to the Constant Voltage
mode.

FAQ
IPS X303 Series Instruction Manual
Q1. I pressed the panel lock key but the output still turns on/off.
A1. The output key is not affected by the panel lock key operation, for ensuring safety.
Q2. The CH3 overload indicator turned on – is this an error?
A2. No, it simply means that the CH3 output current reached the maximum 3.0A and the
operation mode turned from CV (constant voltage) to CC (constant current). You can
continue using the power supply, although reducing the output load is recommended.
Q3. The specifications do not match the real accuracies.
A3. Make sure that the power supply is powered on for at least 30 minutes, within +20 to
+30°C.
Q4. The internal memory is not recording the panel setting correctly – the output should be
on.
A4. The output is always stored or recalled as “off” to ensure safety.
