All of the sensitive electronic marine equipment used today
incorporate solid state components and semiconductors. This
type of equipment is prone to failure because of the regular
occurrence of high voltage surges, spikes and EMF (Electromagnetic
Force) on the DC power supply and it's affect on these sensitive
components. These damaging affects on the DC power supply are
caused by many types of equipment used on the boat and include,
electric starter motors, winches, battery chargers, faulty alternators,
voltage regulators, bilge pumps, AC inverters and even electric
toilet pumps.
Spikes and surges occur whenever an inductive load is connected
or disconnected across the power supply and can generate spikes
and surges greater than 1000V DC. Spikes and surges if they
have sufficient energy will cause an immediate equipment failure.
Each time you start up or shut down your marine engine, use
electric winches, bilge or water pumps, high voltage surges
and spikes are generated and chip away of the semiconductor
junctions and other sensitive components slowly destroying
them, until one day in a weakened condition a transistor,
IC chip, or other component fails.
Surge Bloc is a highly effective DC line filter specifically
designed for the marine environment to limit dangerous high
voltage spikes and surges on the DC power supply from reaching
your sensitive marine electronic equipment. |
