CHAPTER 1 GENERAL INFORMATION

1.1 USER MANUAL CONTENT

This user’s manual contains the operating instructions, installation instructions and specifications of the Genesys 5000W 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 UserManual for PowerSupply IEEE Programming Interface.

1.2 INTRODUCTION

1.2.1 General description

Genesys power supplies are wide output range, high performance switching power supplies. The Genesys series is power factor corrected and operates from worldwide AC voltage range. Output

voltage and current are continuously displayed and LED indicators show the complete operating status ofthe power supply. The Front panel controls allow the user to set the outputparameters, 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.

1.2.2 Models covered by this manual

1.2.4 Multiple output power system

The Genesys power supplies series can be configured into a programmable power

system of up to 31 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 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)

1.2.6 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).

1.2.7 Parallel operation

Genesys power supplies of the same output voltage and current rating canbe paralleled in

master-slave configuration with automatic current sharingto increase power available.

1.2.8 Output connections

Output connections are made to rear panel bus-bars for models up to 100V and to a 4terminal wire clamp connector for models above 100V 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 Genesys 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 Genesys power supplies have a compact and lightweight package

which allows easy installation and space saving inthe application equipment.

3.1 GENERAL

This chapter contains instructions for initial inspection, preparation for use and repackaging for shipment. Connection to PC, setting the communication port and linking Genesys power supplies are described in Chapter 7.

WARNING

The Genesys series is intended only for installation in Restricted Access Location (RAL). Access to Hazardous parts (rear side of the power supply) shall be prevented after installation.

Genesys power supplies generate magnetic fields which might affect the operation of other instruments. If your equipment is susceptible to magnetic fields, do not position it adjacent to the power supply

NOTE

WARNING

through the front panel slits.

3.2 PREPARATION FOR USE

To avoid electric shock hazard, do not insert conductive parts

n order to be operational the power supply must be connected to an appropriate AC source. The AC source voltage should be within the power supply specification. Do not apply power before reading, Section 3.6 and 3.7.

Table 3-1 below, describes the basic setup procedure. Follow the instructions in Table 3-1 in the sequence given to prepare the power supply for use.

3.3 INITIAL INSPECTION

Prior to shipment this power supply was inspected and found free of mechanical or electrical defects. Upon unpacking of the power supply, inspect for any damage which may have occured in transit.

The inspection should confirm that there is no exterior damage to the power supply such as broken knobs or connectors and that thefront panel and meters face arenot scratched or cracked. Keep all

packing material until the inspection has been completed. If damage is detected, file a claim with carrier immediately and notify the Lambdasales or servicefacility nearest you.

3.4 RACK MOUNTING

The Genesys power supply seriesis designed to fit in a standard 19” equipment rack.

3.4.1 To install thePower Supply in a rack:

1. Use the front panel rack-mount brackets to install the power supply in the rack.

2. Use a support bar toprovide adequate supportfor the rear of the power supply. Do notobstruct

the air exhaust at the rearpanel of the unit.

WARNING

Some components inside the power supply are at AC voltage even when the On/Off switch is in the “Off”position. To avoid electric shock hazard, disconnect the line cord and load and wait two minutes before removing cover.

CAUTION

AC Input Wires No Conductor Pretreatment: Phoenix Contact clamping parts are designed so

that all kindsof copper conductors can be clamped withoutpretreatment. It is forbidden to solder the conductors. The solder tin yields and fractures under high pressure. The result is increased contact resistance and an excessive temperature rise. In addition, corrosion caused by pickling or fluxes has been observed on soldered conductor ends. Notch fractures at the transition point from the rigid tothe flexible conductorarea are also possible.

The power supply ON/OFFswitch is not the main disconnect device and does not completely disconnect all the circuits from the AC source. An appropiately rated disconnect device such as circuit breaker, type B plug on power cord, ...etc., shall be provided in the final installation. The disconnect device shall comply with UL/IEC 60950-1 requirements andshall be easily accessible.

3.7.1 AC Input Connector
