For generating the bus voltage for a line with up to
64 bus devices. With integrated choke to decouple
the power supply from the bus and a switch to disconnect
the power and reset the bus devices connected
to the line.
Can be connected to the mains with plug-in screw
terminals. For installation on DIN rails EN 50022.
The bus is connected using a bus connecting terminal;
a data rail is not necessary. External lead
gel batteries with a DC 12 V (SELV) voltage can be
connected to the emergency power input for buffering
the bus voltage or IC 1 Internet controller
power supply. The integral buffer circuit ensures
that the 6-15 Ah lead gel batteries are used as
buffers or recharged.

Mains voltage: AC 230 V, 50-60 Hz
Emergency input: for lead gel battery 6-15 Ah with
DC 12 V (SELV)
Charge retention current: max. 250 mA
Output voltage: DC 29 V ±1 V
Output current: max. 320 mA, short-circuit-proof
Device width: 5 modules = approx. 90 mm

-Accessories: Lead gel battery, art. no. 668990.
