Wire Selection Wires that are selected must be large enough to
withstand a short circuit and limit voltage drops to
no more than 2V per wire. Use the table below to
help make a suitable selection.
AWG Max Current A(Amp)
24 7.64
22 10.0
20 13.1
18 17.2
16 22.6
14 30.4
12 40.6
10 55.3
Load Line
Inductance
Considerations When using the PEL-2000 load generator, voltage
drop and voltage generated due to load line
inductance and current change must be taken into
account. Extreme changes in voltage may exceed
the minimum or maximum voltage limits.
Exceeding the maximum voltage limit may
damage the PEL-2000.
To determine the voltage generated, the following
equation can be used.
E = L x (∆ I / ∆ T)
E= voltage generated
L=load line inductance
∆ 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.
