THE FCC WANTS YOU TO KNOW
This equipment has been tested and found to comply with the limits for a Class A digital device, pursu-
ant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment.
This equipment generates uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference, in which case
the user will be required to correct the interference at his own expense.
FCC WARNING
Modifications not expressly approved by manufacturer could void the user authority to operate the
equipment under FCC Rules.

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.
Lambda Americas shall not be liable for user’s failure to comply with these requirements.
INSTALLATION CATEGORY
The GenesysTM power supply series has been evaluated to INSTALLATION CATEGORY II. Installation
category (over voltage category) II: local level, appliances, portable equipment etc. With smaller tran-
sient 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 Lambda Americas service personnel only. For continued protec-
tion against risk of fire, replace only with the same type and rating of fuse.
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 GenesysTM power supply series has three input ranges de-
pending on the model type ordered. Ranges are 180-253 Vac/360-440 Vac/432-528 Vac, 50-60Hz. For
safety reasons, the mains supply voltage fluctuations should not exceed above voltage range.
LIVE CIRCUITS
Operating personnel must not remove the instrument cover. No internal adjustment or component re-
placement is allowed by non-Lambda Americas qualified personnel. Never replace components with
power cable connected. To avoid injuries, always disconnect power, discharge circuits and remove ex-
ternal voltage source before touching components.
PARTS SUBSTITUTIONS & MODIFICATIONS
Parts substitutions and modifications are allowed by authorized Lambda Americas service personnel
only. For repairs or modifications, the instrument must be returned to an authorized Lambda Americas
service facility.
WARNING OUTPUT TERMINALS 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.

CHAPTER 1 GENERAL INFORMATION
1.1 USER MANUAL CONTENT
This User’s Manual contains the operating instructions, installation instructions and specifications of the
GenesysTM 15KW and 10KW power supply series. The instructions refer to the standard power sup-
plies, including the built-in RS232/485 serial communication. For information related to operation with
the optional IEEE programming, refer to User’s Manual for Power Supply IEEE/IEMD Programming In-
terface. For information related to operation with the optional LAN programming, refer to the User’s
Manual for Power Supply LAN Programming Interface.
1.2 INTRODUCTION
1.2.1 General Description
GenesysTM power supplies are wide output range, high performance switching power supplies. The
GenesysTM series is power factor corrected and operates from specified 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
protections levels (Over-Voltage protection, Under-Voltage limit and Foldback) and preview the set-
tings. The rear panel includes the necessary connectors to control and monitor the power supply opera-
tion by remote analog signals or by the built-in serial communication (RS232/485). GPIB programming
and Isolated-Analog programming/monitoring are optional
1.2.2 Features and options
∗Constant Voltage / Constant Current with automatic crossover.
∗Embedded Microprocessor Controller.
∗Built-in RS-232/RS-485 Interface.
∗Voltage & Current high resolution adjustment by digital encoders.
∗High accuracy programming/readback.
∗Last Setting Memory.
∗Independent Remote ON/OFF (opto-isolated) and remote Enable/Disable.
∗Remote sensing to compensate for voltage drop of power leads.
∗External Analog Programming and Monitoring standard (0-5V or 0-10V, user selectable).
∗Zero stacking-no ventilation required at the top and bottom surface of the power supply.
∗Optional GPIB interface (SCPI compatible).
∗Optional Isolated Analog programming/monitoring (0-5V or 0-10V, user selectable and 4-20mA).

1.2.3 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 On/Off control.
5. Output current measurement.
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).
1.2.4 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).
1.2.5 Parallel operation
GenesysTM 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.
1.2.6 Output connections
Output connections are made to rear panel via bus-bars up to 300V. For greater than 300Vovia stud
terminals. Either the positive or negative terminal may be grounded or the output may be floated. Con-
tact 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.
1.2.7 Cooling and mechanical construction
The GenesysTM series is cooled by internal fans. At the installation, care must be taken to allow free
airflow into the power supply via the front panel and out of the power supply via the rear panel.
CAUTION
Observe all torque guidelines within this manual. Over torqueing may damage
unit or accessories. Such damage is not covered under manufacturer’s war-
ranty
