    3.4. Rack Mounting The Genesys Power Supply Series is designed to fit in a standard 19” equipment rack. 3.4.1. To Install the Power Supply in a Rack: 3.4.1.1. Use the front panel rack-mount brackets to install the Power Supply in the rack.
  • Page 42 WARNING Some components inside the Power Supply are at AC/DC voltage even when the AC Input On/Off switch is in the “Off” position. To avoid electric shock hazard, disconnect the AC input and load (DC Output) and wait 15 minutes before removing any cover. The Power Supply AC On/Off switch is not the main disconnect device and does not completely disconnect all internal circuits from the AC power source.

    The Protective Earth Ground must be connected before applying AC Line Power to the Power Supply. 3.8. Turn-On Checkout Procedure 3.8.1. General The following procedure ensures that the Power Supply is operational and may be used as a basic incoming inspection check. Refer to Fig. 4-1 and Fig. 4-2 for the location of the controls indicated in the procedure.
  • Page 44 c) Press the front panel AC ON/OFF switch to the On position. d) Turn On the output by pressing the OUT pushbutton (the front panel OUT LED should illuminate). e) Observe the Power Supply CURRENT display and rotate the CURRENT encoder. Ensure that the Output current varies while the CURRENT encoder is rotated.

  • Page 45: Connecting The Load

    a) Connect a variable load across the unit output that ranges from 5-15% of rated Output current. Set the load current to 5% of rated Output current. b) Ensure that the Output voltage is set to approximately 10% of the unit Output voltage rating.

  • Page 47 Twisting the load wires reduces the parasitic inductance of the cable, which could produce high frequency voltage spikes at the load and the Output of the Power Supply (because of current variation in the load itself). The impedance introduced between the Power Supply output and the load could make the ripple and noise at the load worse than the noise at the power supply rear panel output.
  • Page 48 Fig. 3-3: Single load connection, local sensing 3.9.7. Connecting Single Loads, Remote Sensing Fig.3-4 shows the recommended remote sensing connection for single loads. Remote sensing is used when, in Constant-Voltage mode, the load regulation is important at the load terminals. Use twisted or shielded wires to minimize any noise pick-up. If shielded wires are used, the shield should be connected to the ground at one point, either at the Power Supply chassis or the load ground.

  • Page 49: Local And Remote Sensing

    3.9.9. Multiple Load Connection with Distribution Terminals If remotely located output distribution terminals are used, the Power Supply output terminals should be connected to the distribution terminals by a pair of twisted and/or shielded wires. Each load should be separately connected to the remote distribution terminals (see Fig.3-6).
  • Page 50 3.10.1. Sense Wiring WARNING There is a potential shock hazard at the sense connector. Local sense and remote sense wires should have a minimum insulation rating equivalent or greater than the maximum Output voltage of the Power Supply. Ensure that the connections at the load end are shielded to prevent accidental contact with hazardous voltages.

  • Page 69 6.1.2. Series Connection for Positive and Negative Output Voltage In this mode, two units are configured as a positive and negative output. Set the Current limit of each power supply to the maximum that the load can handle without damage. It is recommended that diodes be connected in parallel with each unit output to prevent reverse voltage during start-up or in case one of the units shuts down.

  • Page 70: Parallel Operation (Single-Wire/Two-Wire Method)

    6.2. Parallel Operation (Single-Wire/Two-Wire Method) Up to four units of the SAME VOLTAGE and CURRENT RATING can be connected in parallel to provide up to four times the Output current capability of one power supply. One of the units operates as a Master and the remaining units are Slaves. The Slave units are Remote Analog programmed by the Master unit.
  • Page 71 2. Setting up the Slave Units Two-Wire method 1. The Output Voltage of the Slave units should be programmed 2-5% higher than the Output Voltage of the Master unit to prevent interference with the Master unit’s control. The Output Current setting of each Slave unit is programmed by the Master unit to the desired load current divided by the number of parallel units.

    8.8. Global Output Commands 8.8.1. Description Global commands are a way to quickly set all power supplies on the RS-232/RS-485 Digital communication bus to the same setting. For example, sending “GOUT OFF” is one way to turn a whole group of supplies OFF at nearly the same time. CAUTION After sending a global command, it is important that the controller wait 200 mSec before sending any more RS-232/RS-485 messages.

  • Page 94: Fast Queries

    8.9. Fast Queries These are commands that read a response very quickly from the Power Supply. They use unprintable character codes. They allow the Power Supply to avoid the normal command processing delays. The processing time for these queries is typically 2ms, so total query speed is 2ms plus the RS-232/RS-485 transmission time.

    Carriage-return terminator 8.9.4. Service Request Messages A Genesys™ power supply can automatically send messages over the RS-232/RS-485 lines when there is a change in operating mode or if a fault occurs. These messages are called Service Requests or SRQs. They are setup with the RS-232/RS-485 status registers (see Section 8.11 and 8.12).

    Refer to Fig. 8-7 for the Status and Error Registers Diagram. NOTE: these registers operate in a way that is similar to the IEEE-488 and SCPI registers (as used by the Genesys™ with the “-IEMD” option), but the structure and command set is different.

    Introduction Isolated Analog Programming is an internal option card for Remote Analog programming of the Genesys power supply series. The option is factory installed and cannot be obtained with IEMD or LAN Interfaces. Output Voltage and Current Limit can be programmed and read back through optically isolated signals which are isolated from all other ground references in the power supply.
