ARGO DIODE Battery Isolator with voltage
compensating diode and alternator energize input
ENGLISH
Diode battery isolators allow simultaneous charging of two or more
batteries from one alternator, without connecting the batteries together.
Discharging the accessory battery for example will not result in also
discharging the starter battery.
The ArgoDiode battery isolators feature a low voltage drop thanks to the
use of Schottky diodes: at low current the voltage drop is approximately
0,3 V and at the rated output approximately 0,45 V.
Warning: hot surface, mount the Argo Diode on non-flammable
surface only!
Compensation diode
All models are fitted with a compensation diode that can be used to
slightly increase the output voltage of the alternator. This compensates
for the voltage drop over the diodes in the isolator.
Care should be taken however to keep cable lengths short and of
sufficient cross section.
Example:
When a current of 100 A flows through a cable of 50 mm² cross section (AWG 0)
and 10 m length (30 ft), the voltage drop over the cable will be 0,26 Volt. Similarly a
current of 50 A through a cable of 10 mm² cross section (AWG 7) and 5 m length
(15 ft) will result in a voltage drop of 0,35 Volt!
Alternator energize input
Some alternators need DC voltage on the B+ output to start charging.
Obviously, DC will be present when the alternator is directly connected to
a battery. Inserting a Diode or FET splitter will however prevent any
return voltage/current from the batteries to the B+, and the alternator will
not start.
The new ArgoDiode isolators have a special current limited energize
input that will power the B+ when the engine run/stop switch is closed.
Installation (see figure below)
1. Always disconnect the battery minus cables before making
alterations to the electrical system.
2. Connect the positive output of the supplying source (alternator) to
the input of the battery isolator.
3. Connect the positive connection of the battery sets to output 1, 2 and
(optional) 3 respectively.
4. Optional: connect the ‘Energize’ blade terminal to the engine
run/stop switch. Minimum cable cross section: 2,5 mm².
5. Optional: connect the voltage sense of the alternator to the
compensation output of the ArgoDiode splitter.
6. Connect the negative poles of the battery sets to the common
negative bus bar.
ARGO DIODE Laadstroomverdelers met
compensatie diode en dynamo ‘energizer’
NEDERLANDS
Met een laadstroomverdeler kunnen meerdere accu’s gelijktijdig geladen
worden met één dynamo.
Tijdens het ontladen zijn de accu’s gescheiden door de diodes. Wanneer
bijvoorbeeld de accessoire accu ontladen wordt zal de start accu volledig
geladen blijven.
Dankzij toepassing van Schottky diodes is het spanningsverlies van de
Argo laadstroomverdelers zeer laag: slechts 0,3 V bij weinig stroom en
0,45 V bij de maximale stroom.
Waarschuwing: Heet oppervlak, monteer de Argo Diode alleen op een
niet-brandbare ondergrond!
Compensatie diode
Alle modellen zijn voorzien van een compensatie diode die gebruikt kan
worden om de dynamospanning iets te verhogen. Daarmee wordt het
spanningsverlies over de laadstroom verdeel diodes gecompenseerd.
Dynamo ‘energize’ aansluiting
Sommige dynamo’s beginnen alleen met laden indien er spanning
aanwezig is op de B+ aansluiting. Een diode of FET laadstroomverdeler
isoleert echter de accu’s van de dynamo zodat deze niet zal starten.
De nieuwe ArgoDiode laadstroomverdelers hebben een aparte stroom
begrensde ‘Energize’ aansluiting waarmee spanning op de B+ aansluiting
gezet kan worden wanneer het contactslot van de motor in de
contactstand gezet wordt.
Installatie (zie schema)
1. Maak voor de montage de min kabels van de accu’s los.
2. Sluit de positieve uitgang van de voedingsbron (dynamo) aan op de
‘Input’ aansluiting van de laadstroomverdeler.
3. Sluit de positieve aansluitingen van de accugroepen aan op
respectievelijk output 1, 2 en eventueel 3.
4. Optioneel: verbind de ‘Energize’ aansluiting met het contactslot.
Draaddikte: 2,5 mm².
5. Optioneel: verbind de voltage sense van de dynamo met de
compensatie diode aansluiting van de ArgoDiode
laadstroomverdeler.
6. Sluit de min kabels van de accu’s weer aan.
