Power supplies for AS interface
1-phase / 1-2-phase / DC, AS-i 30 V (with data decoupling)
■
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 contain performance-optimized data decoupling for
separating communication signals and supply voltage. As the
result, AS-Interface is able to convey both data and power along
a single line. The power packs are overload and short-circuit
proof.
Dimensions
AS-Interface power supply units have compact dimensions in
widths of 50 / 70 / 120 mm. No clearance to other devices is
required when mounting.
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 automatically in the event of a ground fault.
•
Integrated overload detection: An output overload is identified
and signalized 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: A ground fault can be
signalized and evaluated by relay contacts over a central
control 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 / 2-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 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-operated plants or plants with
uninterrupted power supply (UPS).
•
Removable terminal blocks in spring-type connection: The
power supply units are equipped with three removable
terminal blocks for simple device replacement: 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 to operate AS-Interface
•
Compact, room-saving footprint
•
Reliable power supply even for large numbers of AS-Interface
modules with high power requirements
•
Increased safety and savings on additional components
owing to the integrated ground fault and overload detection
•
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)
