4.2.7 Grounding Screw
The chassis of N36100 is insulated from the inner live conductor. Normally, the
chassis is uncharged. If there is an accident which causes the chassis to be charged,
there is a potential difference between the chassis and the ground at this time. If it is
not well grounded and the operator accidentally touches the chassis, it will form a
closed-circuit through the human body and cause danger. Therefore, a reliable
grounding must be made between the chassis and ground to have the same potential.
In addition, a reliable grounding can also prevent the accumulation of static
electricity.

5.2 Output Inspection
The output inspection can ensure that N36100 can reach its rated output and can
perform the operations on the front panel properly.
5.2.1 Output Voltage Inspection
Steps to verify N36100’s basic voltage function without connecting to a load:
1. Press the power switch.
2. Set voltage to 1V.
3. Press On/Off button to output.
4. Check if the readback voltage is close to 1V.
5. Check if the voltage can be set from 0V to full range.
5.2.2 Output Current Inspection
Steps to verify N36100’s basic function during output short-circuit:
1. Press the power switch.
2. Make sure the output is OFF.
3. Connect an insulated wire to short circuit the positive and negative electrodes
at the output of N36100. The wire used should be able to bear the maximum output
current of N36100.
4. Set current to 1A.
5. Press On/Off button to output.
6. Check if the readback current is close to 1A.
7. Check if the current can be set from 0A to full range.

Note: Please refer to the recommended wire gauge selection table in the appendix.
6 Load Connection
6.1 Load Wire
Load wire is not included among N36100 series standard accessories. Users need to
prepare load wire. Please refer to the follow requirements while selecting load wire.
1. The maximum allowable current of wire.
2. The insulation level of wire should not be lower than the maximum output
voltage of the power supply.
3. The maximum wire length and voltage drop.
4. Noise and impedance effects on the load wire.
6.2 Maximum Allowable Current
The following two factors should be considered when selecting the wire gauge.
1. The wire should be thick enough to avoid overheating when carrying rated load
current or load short-circuit current. The greater shall prevail.
2. The wire gauge should be selected properly to minimize the voltage drop on each
wire and to prevent excessive output power consumption of the power supply, which
affects the load regulation. Although N36100 series adopts remote sense to
compensate the voltage, it is still recommended to minimize the voltage drop.
6.3 Effect of Noise and Impedance
In order to reduce noise or radiation, the load wire and the remote sense wire should
be twisted pair. The wire length should be as short as possible. Shielded wires must
be used in high noise environments. The shielding part is connected to chassis
through the grounding screw hole on rear panel.
Note: Please refer to the recommended wire gauge selection table in the appendix.
Warning: Please turn off the AC input power before changing any connections on the
rear panel. Before supplying power, please check and confirm that all connections are
fastened. Touching any terminal or interface on the rear panel with N36100 powered on
may cause electric shock.

Hunan Next Generation Instrumental T&C Tech. Co., Ltd.
NGI lNGI N36100 Series Wide Range High Voltage Programmable DC Power Supply
17
Even if the noise is not loud, the load wire and remote sense wire should also be
twisted pair to reduce coupling and increase the stability of power supply. The
remote sense wire must be separated from AC input power cord.
Twisted-pair load wire can reduce the parasitic inductance of the wire and prevent
high-frequency voltage peak on the load and the output of power supply, caused by
fluctuation of the load current.
The impedance between the output of power supply and the load makes the ripple &
noise on the load higher than at the rear panel terminal of power supply. If necessary,
an additional filter circuit with a bypass capacitor can be connected to the load to
limit the high-frequency load current.
6.4 Inductive Load
When using N36100 to supply power to inductive loads such as motors, users can
connect a diode across the output of N36100 since the inductive load will produce a
voltage spike which is harmful to N36100. The rated voltage and current of the diode
should be higher than the rated output voltage and current of power supply. The
negative polarity of diode is connected to the positive output of N36100. The
positive polarity is connected to the negative output of N36100.
When using N36100 to supply power to inductive loads such as motors, load
transients, such as counter electromotive force from motors, may occur. Please
connect a surge current suppressor across the output of N36100 to protect N36100.
The rated breakdown voltage of surge current suppressor must be approximately
10% higher than the rated output voltage of N36100.
6.5 Local Sense and Remote Sense
The four-wire interface at rear panel is used for local sense and remote sense. Please
refer to four-wire interface introduction. N36100 is supplied with 4-pin green
connector for remote sense at the rear panel.

Figure 14 4-pin Green Connector
6.5.1 Local Sense
In local sense, output voltage is adjusted at the output terminal of N36100. This way
does not compensate for the voltage drop on the load wire. It is recommended to
use local sense when the load current is low or the load regulation is not very critical.
6.5.2 Remote Sense
Due to the parasitic resistance on the wire, a voltage drop will be generated on the
wire after the current flows. Assuming that output of the power supply is set to
55V/10A and the resistance of the load wire is 0.5 ohms, a 5V voltage drop will be
generated on the wire. The actual voltage reaching the load is only 50V, which affects
the output accuracy of the power supply. In this case, it is necessary to compensate
for the voltage drop on the wire.
The remote sense wire is directly connected to the load from four-wire interface on
the rear panel of power supply. Since the remote sense wire is directly connected to
the high impedance measurement circuit inside the supply, and the current on
remote sense wire is very low, the voltage drop generated is negligible. The voltage
across the load is fed back to the power supply control loop via remote sense wire.
The supply will adjust its output to compensate for the voltage drop on the load wire
so that the voltage across the load is equal to the set voltage.
It is recommended to use remote sense when load regulation is very critical. The
procedure is as below.
1. Press the power switch to shut off the power supply.
2. Disconnect the jumpers on the 4-pin green connector.
3. Connect S+ to positive polarity on load and S- to negative polarity on load with
proper wire.
4. Plug the connector into the four-wire interface on rear panel of supply.
5. Connect the output of power supply to the load.
6. Press the power switch to power on the power supply.
Note: On the 4-pin connector, jumpers have been used to connect S+ to +and S- to -.
When using local sense, please put the 4-pin connector at rear panel. Unplugging the
connector will leave the remote sense terminal disconnected, which will affect the
voltage regulation and may cause the power supply to be unstable and dangerous.
