AS-Interface power on three phases Data sheet Input: 3 AC 400-500V No neutral wire required Output: 30.5V / 8A AS Interface data decoupling Infrared (IR) addressing mode Overload protection by FUSE Mode For highly demanding industrial applications Appr.No. 41701 Short description Data and energy: The primary switched mode DIN rail power supply SLA8.300 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 ASInterface systems. Fast addressing of slaves: The "IR addressing mode" selectable via jumper interrupts the data com- 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 restart the data communication. Safe operation by FUSE Mode: The device features a FUSE Mode, which permanently switches off the output in the event of failure and the unit at overload, short-circuit or overtemperature and thus protects the relatively thin AS-Interface line and the attached components. Triggering of the FUSE Mode is indicated by a flashing LED. System restart requires the intentional activation of a reset button on the front side of the unit. Thus, an accidental restart is prevented and the slaves are protected against damage.

Data sheet FUSE Mode The FUSE Mode (electronic fuse in the output) protects the unit from overload and overtemperature. The FUSE Mode acts as a fuse for the secondary side and protects cables and slaves.
