Thank you for purchasing Wakespeed Offshore’s Model WS100/12 Multi-
Stage Voltage Regulator. Designed by Michael Frost, one of the pioneers of
smart, multi-stage battery charging systems, the Wakespeed WS100/12
voltage regulator provides optimal care for your batteries, when used in
conjunction with a P-type, externally regulated alternator.
The WS100/12 was designed specifically to provide the user with an ex-
tremely simple interface — only two adjustments are required to deliver
tailored charging to your batteries. A convenient five-position rotating
switch enables the user to select one of five programs based on battery
type: standard flooded/gel, standard AGM, Carbon Foam, deep cycle
flooded and high-density AGM/TPPL.
In addition to the selectable programs for battery type, the WS100/12
provides the ability to adjust the maximum regulator field output, making
it possible to reduce alternator horsepower load to the engine and belt.
Four settings are available: 100% (no field reduction), 90%, 75% and
50% field output.
The WS100/12 can be used alone, or in conjunction with optional WS-
100-ATS and WS-100-BTS alternator and battery temperature sensors.
With the temperature sensors installed, the WS100/12 can monitor and
respond to changes in ambient battery temperatures and reduce charging
output if the alternator temperature exceeds safe operating temperatures.
