Short description
Data and energy:
The primary switched mode DIN rail power supply SLA3.100 specifically
supplies AS Interface® systems with energy. The AS-Interface bus technology allows to connect up to 62 participants to a control and to supply
them with energy with a single two-conductor cable. When connecting
slaves, the yellow AS-Interface cable offers the high degree of protection
IP67 in conjunction with the insulation displacement. The communication signals of the individual network participants are modulated onto
the supply voltage. For this purpose, specific power supply units with integrated data decoupling are required for AS-Interface systems.

munication on the yellow AS-Interface cable. Participants with an infrared interface can then quickly be assigned a new ID address by means of
an infrared programming unit without the need to disconnect them
from the AS-Interface cable. Afterwards, the "Communication Mode"
can be selected again to re-start the data communication.
Fit for the world market:
The input voltage range of the unit can be selected on the front panel.
Thus, it can be operated worldwide on all usual single-phase line voltages. International (IEC 60950) and various national (CBscheme) approvals
allow for worldwide application.

Fast addressing of slaves:
The "IR addressing mode" selectable via jumper interrupts the data com-
