Westerbeke WPDS SERIES Manual

M.Y. SIRDAR of New Zealand by De Vries-Lentsch.
Static excitation makes use of non-moving electronic circuits
to regulate voltage output so that sudden severe load changes
neitheroverpower nor starve sensitive
electronic equipment.
Ourdependable generator sets have been installed in many of
the world's finest yachts,providing shore-power luxury and
convenience anywhere on the water. Important reasons
for
their selection include: lightweight, compact size, quick
unfailing starts,smooth quiet operation, superior design,
quality components, and excellent performance records.
These performance records have been helped bythe
accessibility and ease of servicing the sets. Westerbeke
generator sets will add pleasure and dependabilityto any
diesel powered vessel.

GENERATOR SETS
FEATURES
Static Exc it ed
Greatly improved electronic volt-
age regulation. No moving parts
or multiple contact points. Easy
to service, no delicate adiusting
necessary.
Precision Governor
Good frequency regulation-
electron ic dev ic es function better.
Quiet, Smooth-running
Low decible engine-generator
assemb li es are vi br ation isolated
on flexible rubber mounts.
Instant Starting
Hi gh cranking speed makes cold
weather starting easy.
Lightweight, Compact
Clever engineering saves inches,
yet preserves accessibility.
Dependable Power

The Wes terbe ke WPDS Series generator sets give you the most
dep endable power a fl oat - power for on shore conveniences as
well as offshore essentials. They are lightweight , and, due to
close coupling, mor e co mp act by quite a few inches than o ther
generators in this range. Their exce llent dependability is wit-
nessed by their frequent use to power aids to navigation. They
have been used on ocean research vessels
where fuel economy
and
operat ion unde r ex treme conditions are additional require-
ment s. When the original B yrd Antarct ic Base Camp was re-
a ctivate d several years ago these Westerbeke generator sets
were chosen.
In addi tion to these standard m odels with their optional varia-
tions , we have a co mplete line of diesel generator sets from 3 to
45kw a
nd can custom build or mod ify anyone of these to su it
specia l requirement s.
Westerbeke diesel generators are sold and serviced by Westerbeke
d
is tri but ors in major po rt cities throughout the United States.
