SVS25 Datasheet, PDF (1/6 Pages) ETAL Group – Systematic integration of protection and distribution functions

Power distribution system SVS25
Description
The new power distribution system type SVS25 meets all requirements
of the automation technology with regard to reliably overcurrent
protection and optimised current distribution.
The track-mountable power distribution system SVS25 distributes the
voltage potentials supplied by a DC 24 V switch-mode power sup-
ply to 8 slots and selectively protects the connected loads by means
of the plugged in circuit protector type REF16-S101-DC24V. The
SVS25 simplifies wiring and distribution with a load current of 10A per
way and a max. total current of 40A in short-circuit-limited DC 24 V
applications. 10 protected »+« load outputs and 10 minus terminals per
slot help significantly reduce wiring time.
Any load circuit which might be disconnected due to overload or short
circuit generates a single signal which will be summarised in a group
signal directly on the power distribution system and which will be fed
back directly to the control unit.
The line entry for the DC 24 V supply as well as the load output
terminals are designed as push-in terminals so that the entire system
can be wired quickly and cost-effectively.
