Options and Fuse Information
Ensure you order the proper instrument option for the mains power that will be used for the instrument.
Options 0EM, 0E3, and 0E9 determine which power-line voltage is selected at the factory. The default is configured
for 230 VAC ± 10%, 47-63 Hz input voltage (option 0E3).
Option Description
0EM 115 VAC ± 10%, 47-63 Hz input voltage
0E3 230 VAC ± 10%, 47-63 Hz input voltage
0E9 100 VAC ± 10%, 47-63 Hz input voltage
Input power for E36102B, E36103B, E36104B, E36105B, and E36106B is 200 VA maximum.
Ensure the correct AC input voltage and fuse settings
Use the proper switch settings
To change the input AC voltage selector on the power supply, use the two AC selector switches on the underside of
the power supply as shown.
For example, to select 230 V, slide the left switch to the left and the right switch to the right, as illustrated in the
diagram below the switches.
To select 115 V, slide both switches to the right, and to select 100 V, slide the two switches towards each other.
Keysight E36100B Series Operating and Service Guide 18
Use the correct fuse
You must use a time delay 2-A fuse for 100- and 115-VAC inputs, and a time delay1-A fuse for 230-VAC inputs:
Part Number Description Manufacturer Application
2110-1639 Fuse 1 A, 250 V Time-delay Littelfuse 230-V line voltage
2110-1640 Fuse 2 A, 250 V Time-delay 100- and 115-V line voltage
To configure the correct fuse, follow the three steps shown below:
Pull the fuse holder out of the
power supply.
Remove and insert the proper
fuse into the fuse holder.
Re-insert the fuse holder into the
power supply.

Keysight E36100B Series Operating and Service Guide 20
Extending the Voltage Range and Current Range
The power supply may be able to provide voltages and currents greater than its rated maximum outputs if the
power- line voltage is at or above its nominal value.
Operation can be extended up to 3% over the rated output without damage to the power supply, but performance
cannot be guaranteed to meet specifications in this region. If the power- line voltage is maintained in the upper end
of the input voltage range, the power supply willprobably operate within its specifications. The power supply is more
likely to stay within specifications if only one of the voltage or current outputs is exceeded.
Series connections
You can connect up to four E36100B Series power supplies up to the output isolation rating of any one supply to
obtain a higher voltage than a single power supply can produce. Series-connected power supplies can be operated
with one load across both power supplies or with a separate load for each power supply. The power supply has a
reverse polarity diode connected across the output terminals so that if operated in series with other power supplies,
damage will not occur if the load is short-circuited or if one power supply is turned on separately from its series
partners.
When the series connection is used, the output voltage is the sum of the voltages of the individual power supplies.
The current is the current of any one power supply. Each of the individual power supplies must be adjusted in order
to obtain the total output voltage.
Parallel connections
You can connect up to four E36100B Series power supplies in parallelto obtain a total output current greater than
a single power supply can produce. The total output current is the sum of the output currents of the individual
power supplies. The output of each power supply can be set separately. The output voltage controls of one power
supply should be set to the desired output voltage; the other power supply should be set for a slightly higher output
voltage. The supply with the higher output voltage setting will deliver its constant current output, and drop its
output voltage until it equals the output of the other supply, and the other supply will remain in the constant voltage
operation and only deliver that fraction of its rated output current which is necessary to fulfill the total load demand.

Constant voltage and constant current
If the output load resistance exceeds the voltage setting divided by the current setting, the instrument will operate
in constant voltage mode. The current will equal the voltage divided by the load resistance.
If the output load resistance is less than the voltage setting divided by the current setting, the instrument will
operate in constant current mode. The voltage will equal the current multiplied by the load resistance.
Specify 2- or 4-wire measurement
You have the option to use the remote sense terminals on the front panel to measure the voltage at the device
under test (DUT). To specify whether you want to use this option:
1. Press [Menu].
2. Turn the knob to Sense Setting and press the knob.
3. Turn the knob to Internal or External and press the knob.
The internal setting sets a relaywithin the power supply to connect the output and sensing connector. This means
that only two wires are used; and remote sensing is disabled. The external setting sets a relay within the power
supply to disconnect the output and remote sensing inputs. This means that four wires are used; and remote
sensing is enabled.

Save or recall the instrument's state
The instrument allows you to save and recall the instrument state in one of 10 memory locations, labeled
0through9. This allows you to quickly configure the instrument for commonly used applications.
An instrument state includes the instrument's output enable status, voltage and current settings, and OCP and OCV
settings. It does not include error codes or LAN configuration information.
To save or recall the instrument state
1. Press [Menu].
2. Turn the knob to Store (or Recall) and press the knob.
3. Turn the knob to an option from Store 0 to Store 9 (or Recall 0 to Recall 9) and press the knob to store or
recall the present state of the instrument in the specified memory location.
4.
The instrument will briefly display DONE.
Configure the Power-on State
The instrument allows you to recallthe power-on state as either the default (*RST) state or the state stored in one of
10 memory locations (0through9). To configure the power-on state:

Remote Control
You can control the instrument remotely in two ways. To program the instrument via SCPI, use Keysight IO
Libraries. To control the instrument via a simulated front panel, use the instrument's Web interface.
Keysight IOLibraries Suite
Keysight IOLibraries Suite is a collection free instrument control software that automatically discovers instruments
and allows you to control instruments over the LAN, USB, GPIB, RS-232, and other interfaces.
E36100B Series Web interface
You can monitor control the instrument from a Web browser by using the instrument's Web interface. To connect,
simply enter the instrument's IP address or hostname in your browser's address bar and hit Enter.
If you see an error indicating 400: Bad Request, that is related to an issue with "cookies" in your Web browser. To
avoid this issue, either start the Web interface by using the IPaddress (not host name) in the address bar), or clear
cookies from your browser immediately before starting the Web interface.
Check the checkbox below the picture of the instrument to enable an indicator on the instrument's front panel. This
is helpful if you have severalE36100B Series instruments and you wish to identify the one to which you are
connected.
The Configure LANtab on the top allows you to change the instrument's LAN parameters; exercise caution when
doing so, as you may interrupt your ability to communicate with the instrument.
