  • Page 47: Series Connection For Increased Output Voltage

    CAUTION Do not connected power supplies from different manufacturers in series or in parallel. 5.14.1 Series connection for increased output voltage In this mode, two units are connected so that their outputs are summed. Set the Current of each power supply to the maximum that the load can handle without damage. It is recommended that di- odes be connected in parallel with each unit output to prevent reverse voltage during start up se- quence or in case one unit shuts down.

    3. Programming by external resistor: Programming by external resistor is possible. Refer to Section 6-5 for details. 4. Programming via the Serial The communication port is referenced to the IF_COM Communication port (RS232/RS485): which is isolated from the power supply output potential. Therefore power supplies connected in series can be daisy-chained using the Remote-In and Remote-Out con- nectors.

  • Page 49: Parallel Operation

    CHAPTER 6 REMOTE ANALOG PROGRAMMING 6.1 INTRODUCTION The rear panel connector J1 allows the user to program the power supply Output Voltage and Current with an analog device. J1 also provides monitoring signals for Output Voltage and Output Current. The programming range and monitoring signals range can be selected between 0-5V or 0-10V using the setup switch SW1.
  • Page 54 REMOTE VOLTAGE PROGRAMMING OF OUTPUT VOLTAGE AND CURRENT LIMIT CAUTION To maintain the power supply isolation and to prevent ground loops, use an isolated programming source when operating the power supply via remote analog programming at the J1 connector. Perform the following procedure to set the power supply to Remote Voltage programming: 1.
