  • Page 27: Load Wiring

    1-4-5. Load Wiring Wire Gauge Before connecting the unit to a power source, the wire considerations gauge must be taken into account. Load wires must be large enough to resist overheating when a short-circuit condition occurs as well as to maintain a good regulation. The size, polarity and length of a wire are all factors in determining if a wire will withstand short circuiting.
  • Page 28 Load Line When using the LSG-H Series load generator, voltage Inductance drop and voltage generated due to load line inductance Considerations and current change must be taken into account. Extreme changes in voltage may exceed the minimum or maximum voltage limits. Exceeding the maximum voltage limit may damage the LSG-H Series.
  • Page 29 Limiting Load Load line inductance can be reduced in two methods. line inductance Method 1 Ensure load wires are as short as possible and twist the positive and negative load wires together. “Twisted pair” will be shown on any connection diagram where the load wires should be twisted together.

  • Page 30: Load Wire Connections

    1-4-6. Load Wire Connections Description The LSG-H Series has input terminals on both the front and rear panels. Follow the procedures below for all load connections. Please adhere to the following precautions to ensure your safety and to protect the unit from damage.

    7-5. Operating Mode Description 7-5-1. CC Mode CC Mode When the unit is set to CC mode it will operate as a constant current load when connected to a constant voltage source. This means the unit will sink a designated amount of current, up to the rated power level, regardless of the voltage.

  • Page 182: Cr Mode

    7-5-2. CR Mode CR Mode When the unit is set to CR mode it will operate as a constant resistance load when connected to a constant voltage (CV) or constant current (CC) source. This means the unit will maintain a set resistance, up to the rated power, regardless of the load voltage or current.

  • Page 183: Cp Mode

    7-5-3. CP Mode CP Mode When the unit is set to CP mode it will operate as a constant power operation when connected to a constant voltage source. This means the unit will maintain a set CP setting value, up to the rated current or voltage level, regardless of the load voltage.

  • Page 184: Cv Mode

    7-5-4. CV Mode CV Mode When the unit is set to CV mode it will operate as a constant voltage operation when connected to a constant current source. This means the unit will maintain the CV setting value, up to the rated power, regardless of the input current.
