SAFETY INSTRUCTIONS
CAUTION
The following safety precaution must be observed during all phases of operation, service and repair of this
equipment. Failure to comply with the safety precautions or warnings in this document violates safety
standards of design, manufacture and intended use of this equipment and may impair the built-in
protections within.
TEXIO shall not be liable for user’s failure to comply with these requirements.
INSTALLATION CATEGORY
The PU power supply series has been evaluated to INSTALLATION CATEGORY II.
Installation category (over voltage category) II: local level, appliances, portable equipment etc. With smaller
transient over voltage than Installation Category (over voltage category) III.
GROUNDING
This product is a Safety Class 1 instrument. To minimize shock hazard, the instrument chassis must be
connected to an electrical ground. The instrument must be connected to the AC power supply mains
through a three conductor power cable, with the ground wire firmly connected to an electrical ground
(safety ground) at the power outlet.
For instruments designed to be hard-wired to the supply mains, the protective earth terminal must be
connected to the safety electrical ground before another connection is made. Any interruption of the
protective ground conductor, or disconnection of the protective earth terminal will cause a potential shock
hazard that might cause personal injury.
FUSES
Fuses must be changed by authorized TEXIO service personnel only. For continued protection against risk
of fire, replace only with the same type and rating of fuse. Refer to maintenance instructions in chapter 9
for fuses rating.
INPUT RATINGS
Do not use AC supply which exceeds the input voltage and frequency rating of this instrument. The input
voltage and frequency rating of the PU power supply series is: 100-240V, 50/60Hz.
For safety reasons, the mains supply voltage fluctuations should not exceed +/-10% of nominal voltage.
WARNING
OUTPUT TERMINAL GROUNDING
There is a potential shock hazard at the RS232/485 and the IEEE ports when using power supplies
with rated or combined voltage greater than 400V and the Positive Output of the Power Supply is
grounded. Do not connect the Positive Output to ground when using the RS232/485 or IEEE.

III
LIVE CIRCUITS
Operating personnel must not remove the instrument cover. No internal adjustment or component
replacement is allowed by non-TEXIO qualified personnel. Never replace components with power cable
connected. To avoid injuries, always disconnect power, discharge circuits and remove external voltage
source before touching components.

1. GENERAL INFORMATION
1.1. USER MANUAL CONTENT
This user’s manual contains the operating instructions, installation instructions and specifications of
the PU 1500W power supply series. The instructions refer to the standard power supplies, including
the built-in RS232/485 serial communication. For information related to operation with the optional
IEEE programming, refer to User Manual for Power Supply IEEE programming Interface.
1.2. INTRODUCTION
1.2.1 General description
PU power supplies are wide output range, high performance switching power supplies. The PU series
is power factor corrected and operates from worldwide AC voltage range continuously. Output
voltage and current are continuously displayed and LED indicators show the complete operating
status of the power supply. The Front panel controls allow the user to set the output parameters, the
protection levels (Over-Voltage protection, Under-Voltage limit and Foldback) and preview the
settings. The rear panel includes the necessary connectors to control and monitor the power supply
operation by remote analog signals or by the built-in serial communication (RS232/485). GPIB
programming and Isolated-Analog programming/monitoring are optional.

units using the built-in RS232/RS485 communication port in the power supply and the RS485
linking cable provided with each power supply.
In a GPIB system, each power supply can be controlled using the optional GPIB controller (factory
installed).
1.2.5 Control via the serial communication port
The following parameters can be programmed via the serial communication port:
1. Output voltage setting.
2. Output current setting.
3. Output voltage measurement.
4. Output current measurement
5. Output on/off control.
6. Foldback protection setting.
7. Over-voltage protection setting and readback.
8. Under-Voltage limit setting and readback.
9. Power-supply start up mode (last setting or safe mode)
1.2.6 Analog voltage programming and monitoring
Analog inputs and outputs are provided at the rear panel for analog control of the power supply. The
output voltage and the current limit can be programmed by analog voltage or by resistor, and can be
monitored by analog voltage. The power supply output can be remotely set to On or Off and analog
signals monitor the proper operation of the power supply and the mode of operation (CV/CC).

3
1.2.7 Parallel operation
PU power supplies of the same output voltage and current rating can be paralleled in master-slave
configuration with automatic current sharing to increase power available.
1.2.8 Output connections
Output connections are made to rear panel bus-bars for models up to 60V and to a 4-terminal wire
clamp connector for models above 60V rated output voltage. Either the positive or negative
terminal may be grounded or the output may be floated. Models up to 60VDC Rated Output shall
not float outputs more than +/- 60VDC above/below chassis ground. Models >60VDC Rated
Output shall not float outputs more than +/-600VDC above/below chassis ground. Contact factory
for assistance with higher float voltage applications.
Local or remote sense may be used. In remote sense, the voltage drop on the load wires should be
minimized. Refer to the specifications for the maximum voltage drop value.
1.2.9 Cooling and mechanical construction
The PU series is cooled by internal fans. At the installation, care must be taken to allow free air flow
into the power supply via the front panel and out of the power supply via the rear panel. The PU
power supplies have a compact and lightweight package which allows easy installation and space
saving in the application equipment.
