Power supply
BFK – V1.0
General description
Installation
Continuous electrical power supplies for KNX installations.
All Ingenium KNX power supply models provide 30 Vdc and
have an auxiliary output available (also 30 Vdc voltage).
This device is available in 80mA, 160mA, 320mA and 640mA
versions.
Characteristics
Models:
• BFK80
o Nominal current: 80mA (l1+l2 < 80mA)
o Size: DIN rail (2 modules)
• BFK160
o Nominal current: 160mA (l1+l2 < 160mA)
o Size: DIN rail (2 modules)
• BFK320
o Nominal current: 320mA (l1+l2 < 320mA)
o Size: DIN rail (4 modules)
• BFK640
o Nominal current: 640mA (l1+l2 < 640mA)
o Size: DIN rail (4 modules)
All versions have KNX bus connection terminal (l1: black/red)
and auxiliary connection terminal (l2: yellow/white). Main
output + auxiliary output cannot overcome the nominal current.
Auxiliary output can be used to supply a further bus line (in
connection with a separate choke) or to supply graphical
touch panels.
Technical information
Power supply - 230 Vac.
Outputs:
• KNX BUS output (black/red connection terminal) with
choke. 30 V DC +1/-2 V, SELV
• Auxiliary output (yellow/white connection terminal) without
choke. 30 V DC +1/-1 V, SELV
Environment temperature range - Operation: from -10ºC to
55ºC / Storage: from -30ºC to 60ºC / Transportation: from 30ºC to 60ºC.
Regulation - According to the directives of electromagnetic
compatibility and low voltage. EN 50090-2-2 / UNE-EN 610006-3:2007 / UNE-EN 61000-6-1:2007 / UNE-EN 61010-1.
Remarks
Feed low voltage lines (KNX bus and inputs) in separate
ducting to that of power (230V) and outputs to ensure there is
enough insulation and avoid interferences.
Do not connect the main voltages (230 V) or any other
external voltages to any point of the KNX bus or inputs.
