    Internal Resistance Internal resistance function is primarily used to simulate battery voltage drop, as a response to load current. In addition, it can be used in cases of voltage drop over long load wires. Power supply output voltage V is set according to voltage setting minus actual load current multiplied by internal resistance value setting (V =V-I×R Internal resistance function is enabled via the Front Panel menu (refer to section 1.8) or the...

    Constant Power Limit The Constant Power Limit function limits the output power provided by the power supply. The Constant Power Limit function is enabled via the Front Panel menu (refer to section 1.8) or the communication command [SOURce]:POWer:STATe <Bool>. Constant power setting range is limited by multiplication of rated voltage by rated current, in steps of 1 watt.

  • Page 155: Advanced Parallel

    Advanced Parallel Up to four units of the same voltage and current ratings can be connected in parallel to provide up to four times of the output current capability. One of the units operates as a master while the remaining units operate as slaves. The configuration of the system (Master-Slave) is automatic. Each unit configures itself according to advanced parallel cable connection.
  • Page 156 Figure 5–11: Parallel Connection with Local Sensing Figure 5–12: Parallel Connection with Remote Sensing CAUTION Make sure the connection between –V terminals is reliable to prevent disconnection during operation. Disconnection may cause damage to the power supply. NOTE With local sensing, it is important to minimize wire length to decrease wire resistance. In addition, the positive and negative wire lengths should be as close as possible to each other to achieve better current balance between power supplies.

    5.9.4 Advanced Parallel System Acknowledge The acknowledge system prevents unintended changes of advanced paralleling assembled systems. Following initial system assembly, the new assembled system has to be “acknowledged”. Any further change in the system configuration has to be “acknowledged” (A change in the system can be done by removing slave units, adding additional slave units or changing the role of a unit from slave to master).
