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
Independent / Tracking Series / Tracking Parallel

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. 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.

IPS X303 Series Instruction Manual

Constant Voltage/ Each output channel is completely transistorized and well- regulated, and

Constant Current 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 The front panel display (CH1, CH2) shows the output voltage or current.

mode

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.

Principle of Operation

Overview Block diagram

The power supply consists of the following. AC input circuit Transformer Bias power supply including rectifier, filter, pre-regulator and
reference voltage source Main regulator circuit including the main rectifier and filter, series
regulator, current comparator, voltage comparator, reference voltage amplifier, remote device and relay control circuit The block diagram below shows the circuit arrangement. The single phase input power is connected to the transformer through the input circuit. Details of each part are described in the next page.

Rectifier Main 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. 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.

OVERVIEW

Current Limiter Overload

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. 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.

IPS X303 Series Instruction Manual

CV/CC Crossover Characteristics

Background CV mode CC mode
Diagram

The IPS X303 series automatically switches between constant voltage mode (CV) and constant current mode (CC), according to load condition. 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. 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
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.
