Overview
AS-Interface power supply unit
for 3 A
AS-Interface power supply units feed 30 V DC into the
AS-Interface cable and supply the AS-Interface components.
They include power-optimized data decoupling for the separa-
tion of communication signals and control supply voltage. As the
result, AS-Interface is able to convey both data and power along
a single line. The power supply units are resistant to overload
and short circuits.
Dimensions
AS-Interface power supply units have compact dimensions in
widths of 50 / 70 / 120 mm. No distances from other devices
need to be observed when mounting the power supply units.
Features
•
Higher rating: The power supply units deliver currents of 2.6 to
8 A.
•
Integrated data decoupling: As the result, AS-Interface is able
to convey both data and power along a single line.
•
Integrated ground-fault detection: The power supply units per-
form the reliable detection and signaling of ground faults ac-
cording to IEC 60204-1. The AS-Interface voltage can be dis-
connected automatically in the event of a ground fault.
•
Integrated overload detection: An output overload is detected
and reported over a diagnostics LED.
•
Diagnostics memory: Any ground faults or overloads on the
output side are stored in a diagnostics memory until the de-
vice is RESET.
•
Remote RESET and remote signaling: Using relay contacts,
a ground fault can be signaled and evaluated by a central
controller and/or indicator light.
•
Diagnostics LEDs: Three different LEDs indicate the status of
the AS-Interface power supply locally at the power supply unit.
•
Ultra-wide input range / two-phase connection: The ultra-wide
input range of 120 to 500 V of the 8 A version means that the
supply units can be used in virtually any network worldwide.
In addition, this version dispenses with the need for an
Nconductor as the device can be connected directly between
2 phases of a network.
•
Operation with 24 V DC: The 3 A power supply unit is also
available as a version with a 24 V DC input. This power supply
unit is suitable for use in battery-powered systems or in sys-
tems with UPS (uninterruptible power supply).
•
Removable terminal blocks with spring-type connections:
For easy exchanging of devices, each power supply unit has
three removable terminal blocks: for the input side, for the
output side and for Signal/RESET connections.

Benefits
•
Complete solution for supplying AS-Interface networks while
making full use of the maximum possible cable length per
AS-i segment
•
Only AS-i masters and AS-i slaves need to be connected to
the AS-Interface cable in order to operate AS-Interface
•
Compact, space-saving dimensions
•
Reliable power supply even for large numbers of AS-Interface
modules with a high power requirement
•
Integrated ground-fault and overload detection saves the
need for additional components and enhances safety
•
Fast fault detection and reduced downtimes thanks to diag-
nostics memory, remote signaling and remote RESET
•
Reduced downtimes as the result of removable terminal
blocks which enable the fast exchanging of devices
•
Ultra-wide input range of the 8 A version permits single-phase
and two-phase operation and saves the need for an N con-
ductor
•
Can be used world-wide thanks to, for example, UL/CSA
approval (UL 508)
•
With the 2.6 A version the output power is restricted to max.
100 W for use in NEC Class 2 circuits
