Short description
Data and energy:
The primary switched mode DIN rail power supply SLA8.300 specificallysupplies AS Interface® systems with energy. The AS-Interface bus
technology allows to connect up to 62 participants to a control and tosupply them with energy with a single two-conductor cable. Whenconnecting slaves, the yellow AS-Interface cable offers the high degreeof 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 ASInterface systems.

munication 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"can be selected again to restart the data communication.

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

FUSE Mode

Electromagnetic Compatibility (EMC)

The FUSE Mode (electronic fuse in the output) protects the unit fromoverload and overtemperature. The FUSE Mode acts as a fuse for thesecondary side and protects cables and slaves.

Indicator:• Activation of the FUSE Mode is indicated by a flashing red LED.
Reset/Restart:• by intentionally pushing the Reset button on the unit front panel• by turning off the mains voltage. Before restarting the unit, wait atleast twice the time the flashing red LED needed to extinguish after
the mains voltage dropped.

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.
