N36100 Series
Wide Range High Voltage Programmable DC Power Supply

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.
