TECHNICAL BACKGROUND

n

CZone

®

A CZone system decentralises the DC

power distribution system, locates circuit

control and protection modules closer to

loads to shorten cable runs and reduce

the size of conductors, significantly

decreasing the cost and weight of the

electrical wiring

harness. The

CZone system

replaces complex

wiring with a single

data wire.

n

Digital Switching

Digital Switching is a

Mastervolt innovation

that radically simplifies installation,

configuration, control and monitoring

of onboard electrical systems. This

CAN-based platform is proven in

the automotive industry and is fully

compatible with most A-brand navigation

systems. It offers you a range of luxurious

and comfortable options, including

remote control.

n

DIP switch

A tiny switch usually found on a printed

circuit board and used to set the various

functions of Mastervolt equipment.

n

Direct current (DC)

Current that only flows in one direction,

such as that in a battery, solar panel,

alternator or battery charger.

n

DNV GL approval

Det Norske Veritas is a Norwegian

classification society for professional

shipping and offshore activities.

The requirements in term of safety

and functionality are very strict, and

approval is required by many insurance

companies.

Most Mastervolt

equipment

easily satisfies

DNV’s stringent

standards.

Germanischer Lloyd is a German

classification society for professional

marine vessels. The requirements in

terms of safety and functionality are

very strict and

this approval is

often necessary

for insurance

purposes.

n

Earth

The electric no-load potential,

also called reference

potential. The negative pole of a battery

is often connected to the steel chassis

of a vehicle or boat, which then serves

as the earth. In US English the term

grounding is used.

n

Earth leakage switch

Monitors the onboard supply for

electrical leakage, switching it off when

leakage exceeds 30 milli-amps.

An earth leakage switch protects you

against an electric shock in the event of

contact with a live component.

n

Efficiency

The efficiency of a power source is

expressed in percentage terms (%).

A device with an efficiency of 90 %,

for instance, has 100 % power at the

beginning and 90 % at the end. The 10

% that is lost is primarily transformed

into heat. The higher the efficiency of an

inverter, the longer the batteries will last.

n

Electrolyte

The liquid in batteries, composed of a

mixture of sulphuric acid and water.

Its specific gravity is 1.280 in a charged

battery and 1.100 in a discharged one.

n

E-marking

A standard that indicates whether

the relevant equipment can be used

on vehicles such as ambulances and

fire engines. In order to qualify for an

E-marking, equipment has to satisfy strict

requirements

in terms of

safety, EMC and

suitability.

Most Mastervolt battery chargers

and inverters comply with these

requirements.

n

EMC

Short for Electro-Magnetic

Compatibility, EMC indicates how

much, if any, electromagnetic

interference a device may produce

and whether it is sensitive to

electromagnetic interference from

the outside. A good example is that

of a battery charger and a microwave

oven. The microwave is not allowed

to produce more interference than

determined by the EMC standard,

and the battery charger may not

be affected by the interference

generated by the microwave.

Naturally, the opposite also holds

true. Requirements in terms of

EMC are established within the CE

framework. Mastervolt equipment

exceeds these strict requirements.

n

E-Propulsion

Electrical propulsion is growing in

popularity and is compulsory in an

increasing number of sailing and

nature areas. A hybrid version is also

available, allowing you to choose

whether to sail using a diesel engine

or electric motor.

n

Float phase

The final step in a

modern 3-step+ charging

process. Although the batteries are

fully charged during this phase, they

receive a maintenance charge, while

the onboard DC circuit is supplied

with power. Charge voltage is 2.25

volt per cell or 13.25 volt for 12-volt

batteries and 26.5 volt for 24-volt

ones at an ambient temperature of

25 °C.

n

Forced inverter

A function on the Mass

Systemswitch. At the push of a

button, a part of the onboard

consumers are powered from the

batteries via the inverter, while the

battery charger stays connected to

power.
