Vad betyder symbolerna på CTEK laddare?
”POWER LAMP” indikerar om att nätkabeln är ansluten till vägguttaget. ”ERROR LAMP” indikerar att batteriklämmorna är felkopplade. Polvändningsskyddet kommer att förhindra att batteriet och laddaren skadas.
Hur lång tid ladda bilbatteri CTEK?
Hur lång tid tar det att ladda det interna batteriet från helt urladdat till fulladdat? Från ”Mindre än 10% kvar” (första lysdioden blinkar) till fulladdat tar det upp till 60 minuter så länge CTEK:s standardtillbehör används.
Hur använda CTEK laddare?
Laddaren ska anslutas enligt fordonets användarmanual. Om rekommendationer saknas i fordonsmanualen, rekommenderar CTEK att den svarta (negativa) klämman (ringkabelskon) monteras på fordonets chassi. Laddare som inte är gnistfria riskerar att skapa gnistor om den positiva och negativa kontakten berör varandra.
What is an alternator?
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used.
How does a synchronous alternator work?
The rotating magnetic field induces an AC voltage in the stator windings. Since the currents in the stator windings vary in step with the position of the rotor, an alternator is a synchronous generator. The rotor’s magnetic field may be produced by permanent magnets, or by a field coil electromagnet.
How is an alternator cooled?
Many alternators are cooled by ambient air, forced through the enclosure by an attached fan on the same shaft that drives the alternator. In vehicles such as transit buses, a heavy demand on the electrical system may require a large alternator to be oil-cooled. In marine applications water-cooling is also used.
How does a brushless alternator work?
After the initial AC voltage buildup, the field is supplied with rectified voltage from the alternator. A brushless alternator is composed of two alternators built end-to-end on one shaft. Until 1966, alternators used brushes with rotating field. With advancement in semiconductor technology, brushless alternators are possible.
