  • Page 25: Voltage Drops

    3 - Installation Voltage Drops The load wires must also be large enough to avoid excessive voltage drops due to the impedance of the wires. In general, if the wires are heavy enough to carry the maximum short circuit current without overheating, excessive voltage drops will not be a problem.

  • Page 26: Remote Sense Connections

    Installation - 3 Remote Sense Connections Under normal operation, the dc source senses the output voltage at the output terminals on the back of the unit. External sense terminals are available on the back of the unit that allow the output voltages to be sensed at the load, compensating for impedance losses in the load wiring.

    10,000 F. Keysight 6612C and Keysight 66312A 6614C If your load capacitance approaches this limit, it is recommended that you do not intentionally trip the OVP and discharge the capacitance through the SCR as part of your normal testing procedure, as this may lead to long-term failure of some components.
