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 perform
the reliable detection and signaling of ground faults according to
IEC 60204-1. The AS-Interface voltage can be disconnected auto-
matically 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 device 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 ver-
sion dispenses with the need for an N conductor 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
systems 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
diagnostics 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 removes the need for an
N conductor
•
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 Class 2 circuits in accordance with NEC
(National Electrical Code)
