Power Supply Unit
PS00C01KNX (160mA)
Product and Applications Description
The power supply unit PS00C01KNX provides the system
power necessary for the instabus EIB. The connection to the
bus line is established by clicking the device onto the DIN-rail
(with a data rail installed) and/or via the bus connection block
located on the front side.
The integrated choke prevents the data telegrams from
shortcircuiting on the bus line. When the built-in reset switch is
operated (operation > 20s), the bus devices are returned to
their initial state.
For each bus line, at least one power supply unit
PS00C01KNX is needed. Up to two power supply units may be
attached to a single bus line.
A second unit is not required unless the supply voltage at a
bus device is less than 21 V. The cable length between the two
power supply units must be at least 200 m.
When more than 30 bus devices are installed in short bus cable distance (e.g. 10 m), e.g. in distribution boards, the power
supply unit PS00C01KNX should be arranged near these bus
devices. The distance between power supply unit
PS00C01KNX and any of its bus devices must not exceed 350
The power supply unit PS00C01KNX has a voltage and current
regulation and is therefore short-circuit proof. Short power failures can be bridged with a backup interval of approximately
200 ms.
To ensure an uninterrupted power supply a separate circuit
with safety separation should be used for the power supply unit
PS00C01KNX’s power supply line.
