Extreme changes in voltage may exceed the minimum or maximum voltage limits.
Page 27 ∆ I= change of current (A) ∆ T= time (us) Load line inductance (L) can be approximated as 1uH per 1 meter of wire. (∆ I / ∆ T) is the slew rate in A/us. Current ∆I time ∆T Voltage Min.
Page 28: Load Wire Connections
1-4-6. Load Wire Connections Description The LSG 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.
Page 29: Using The Front Panel Input Terminals
1-4-7. Using the Front Panel Input Terminals Description The front panel input terminals feature polarity- distinct caps and accept M6 sized crimped terminals. The front panel input terminals on the LSG Series are physically connected to the rear Caution panel terminals. Step Turn the power off from the rear panel or put the unit into standby mode.
Page 30: Using The Rear Panel Input Terminals
DUT is connected to the front terminals Ensure the power is off before making any connections to the LSG Series. Caution In the following diagrams, the cable wiring is not shown for clarity.
Page 31 Remove the screw holding the top cover to the bottom cover. Line-up the bottom cover with the notches in the output terminals. Place the top terminal cover over the bottom cover. Detail Use your thumb to slide the terminal covers shut, as shown in the diagram below.
Page 32: Using The Terminal Cover (Pel -013)
When the top and bottom covers are flush, reinsert the screw that was removed in step 1. 1-4-10. Using the Terminal Cover (PEL -013) Description The flexible rear panel terminal cover should be used when the load wiring becomes too thick to be used with the PEL-011 terminal cover.
Page 33: Remote Sense
2. Secure the insulation sheets using the supplied velcro fasteners. 2 fasteners should be used for each sheet. Fasteners 1-4-11. Remote Sense Description Remote sense can be used to help compensate for long cable length. The longer the cable, the higher the potential resistance and inductance, therefore a short cable is best.

Page 115: External Control
4. EXTERNAL CONTROL 4-1. Analog Control The Analog Control subsection describes how to use the J1 Frame Control Connector for voltage or resistance control. The J2 connector, located under the J1 connector is used for parallel control. See page 129 for the details J1 and J2 connectors. 4-1-1.
Page 116: External Voltage Control - Overview
4-1-2. External Voltage Control - Overview Background External voltage control of the CC, CR, CV and CP mode is accomplished using the J1 connector on the rear panel. An input voltage of 0~10V corresponds to 0% ~ 100% of the rated current (CC mode), rated voltage (CV mode), or rated power (CP mode).
Page 117 Rated Power External Voltage Operation Turn the power off from the LSG Series and from the load. Connect the external voltage across pins 1 and 3 of the J1 connector. Turn the power on the LSG Series. Set the operating mode and range.
Page 118: External Resistance Control - Overview
A resistance of 0kΩ~10kΩ is used to control the input current, voltage, resistance or power on the LSG Series. The input can be configured to vary in proportion to the external resistance or the inverse. See page 107 for more details on proportional and inverse resistance control.
Page 119: External Resistance Control - Operation
4-1-5. External Resistance Control – Operation Description External resistance control can be used to control the current, voltage, resistance and power for CC, CR, CV and CP modes. Configuration for each operating mode is the same. CC Mode Proportional Control: Input current = rated current ×...
Page 120 Under similar circumstances using proportional control, an unexpectedly high input would result. Operation Turn the power off from the LSG Series and from the load. Connect the external resistance across pins 1 and 3 of the J1 connector. Turn the power on the LSG Series.
Page 121: Turning The Load On Using External Control
 The J1 connector is now ready for  external resistance control. Reset the power to apply the settings.  The unit is now ready for external  resistance control. 4-1-6. Turning the Load On using External Control Description The load can be turned on and off with an external switch connected to pins 7 and 12 of the J1 connector.

The voltage range used to represent the full scale current range from the IMON OUT terminal and from the IMON pin on the J1 connector depends on the current range settings.
Page 127: Parallel Operation
The LSG Series can be connected in parallel to increase the total power capacity of a single unit. The LSG Series can operate with up to 5 units in parallel. A single unit is designated as a master unit and any other connected units as slaves.
Page 128: Configuration
MASTER Ferrite Load cores wiring Sense wiring SLAVE 1 SLAVE 2 SLAVE 3 Only the rear terminals can be used for parallel connections. Cautions Make sure all connections are correct before turning on the load. Incorrect connections could damage the units. Only units of the same type and rating can be used in parallel (except for when the LSG-2100S booster pack is used with the LSG-1050).
Page 129 Master J2  Slave1 J1 Slave1 J2  Slave2 J1 and so on. Turn the load units on. Main On the designated master unit, press > Configure [F5] > Next Menu [F4] > Parallel[F1].

4-2-4. Turning the Load On Description Operating the LSG Series in parallel mode is the same as for single units. When using the units in parallel, the load line inductance could be increased or the stability of Note the units could be reduced. It may be necessary to reduce the response speed setting to increase stability.
