Short description
Data and energy:
The primary switched mode DIN rail power supply SLA8.100 specificallysupplies 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 connectingslaves, 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.
Fast addressing of slaves:
The "IR addressing mode" selectable via jumper interrupts the data communication on the yellow AS-Interface cable. Participants with an infrared interface can then quickly be assigned a new ID address by means ofan infrared programming unit without the need to disconnect themfrom the AS-Interface cable. Afterwards, the "Communication Mode"Input

can be selected again to re-start the data communication.
Safe operation by FUSE Mode:
The device features a FUSE Mode, which permanently switches off theoutput in the event of failure and the unit at overload, short-circuit orovertemperature and thus protects the relatively thin AS-Interface line
and the attached components. Triggering of the FUSE Mode is indicatedby a flashing LED. System restart requires the intentional activation of a
reset button on the front side of the unit. Thus, an accidental restart isprevented and the slaves are protected against damage.
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.

Operation without AS-Interface: This AS-Interface PSU has an inductive output. When operating without AS-Interface structure (e.g. ina laboratory test) you should connect a 470µF / 35V capacitor between
AS-Interface + and AS-Interface – as commercial electronic loads in
combination with the data decoupling often tend to oscillate, and theoscillation may exceed the permitted modulation voltage. Otherwise,
equipment may be destroyed.
