G34850000700

Supply Coupling UnitType G 3485 0000• For systems using a combined communication-supply bus (3-wires)• Input from a standard 15... 30 VDC power supply• Coupling of transmission- and supply-common• Output current 4 A max.• H4-housingProduct DescriptionOrdering KeyG 3485 0000 700The supply coupling unit is mainly used in those applications, where multiple Dupline®modules of the type G21...700 are to be supplied through a DC-bus. Since these modules use the same wire for the commonof the transmissionsignalandthe“minus” oftheDC-supply, the G 3485 000 assures proper coupling of the supply to maximise the noise immu- nity of the entire installation. To supply a current ≤ 4 A (up to 25°C) / ≥ 3 A (under 50°C), multiplecouplingunitsmay be installed in parallel.Type: Dupline® H4-Housing Power supplyType SelectionSupply Ordering no.15 to 30 VDC G 3485 0000 700Output SpecificationsOutputOutput voltage VBB15 to 30 VDC (pulsating) Output current≤ 4 A (up to 25°C)≥ 3 A (under 50°C) Short-circuit protection NoneOutput voltage drop≤ 1 VDCSupply SpecificationsPower supplyInstallation cat.
