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.

Considerations
When using the PEL-2000A series, 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-
2000A series.
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.
