Example
1
Connectors
Connectors for hookup wire assemblies and test
resistors, item numbers 5, 6, 9, 10, and 11.
•
(Qty. 6) #10 fork lugs similar to Tyco part
number 52951.
•
(Qty.14) Stackable, gold-plated banana
plugs/jacks similar to Pomona model 4897-0.
Used for lower current connections, and
connections to the load resistors (items 10
and 11) used for noise testing.
•
(Qty. 4) Sheathed banana jacks similar to
Pomona model 4834 to put connectors on
the resistors.
2
AC power source
Variable AC output from 90 to 265 VAC with at
least 750 VA capacity.
Kikusui PCR2000M
3
Electronic load
Variable DC load capable of 6 ADC and 40 VDC
B&K Precision 8510
4
DC voltmeter
Voltage measurement at 12 mV through 40 V to
better than 100 ppm accuracy with the ability to
multiply the result by a scalar.
Keithley 2000 DMM
5
High-current hookup wire (high-
current connections are indicated
with bold lines in the setup
illustrations)
18 AWG (minimum) hookup wire assemblies.
To perform all tests, the following wire assemblies
need to be created:
•
#10 fork lug to #10 fork lug, Qty. 2.
•
Stackable banana to #10 fork lug, Qty. 2
•
Stackable banana to bare wire, Qty. 2.
Wire lengths are not critical.
6
Low-current hookup wire (low-
current connections are indicated
with light lines in the setup
illustrations)
22 AWG (minimum) hookup wires.
To perform all tests, the following wire assemblies
need to be created:
•
Banana plug to Banana plug, Qty. 2
•
Bare Wire to stackable Banana, Qty. 2
•
Bare Wire to Banana, Qty. 2
Wire lengths are not critical.
7
50 mΩ precision shunt resistor
0.050 Ω ±100 ppm at 25 W ±4 ppm/°C temperature
coefficient.
Guildline 9230A-50
8
Current sense resistor cabling
Kelvin 4 terminal measuring cables for shunt
Resistor to voltmeter.
Guildline 92301 cable
set
9
50 mΩ resistor for remote sense
testing (2 required)
One of these 50 mΩ resistors
may be substituted with item 7.
0.050 Ω, 5 W.
To perform the tests as illustrated, both leads of
each resistor require a Banana Jack connector
