3RX9502-0BA00 Siemens AS-i Power Supply Original Brand New

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 separation of communication signals and 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 automatically in the event of a ground fault.
• Integrated overload detection: An overload on the output side is detected and reported via a diagnostics LED.
• Diagnostics memory: Any ground faults or overloads on the output side are stored in a diagnostics memory and signaled 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/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 two 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-loaded terminals: 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.

• 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, space-saving dimensions
• Reliable power supply even for large numbers of AS-Interface modules with high power requirements
• 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 1-phase and 2-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)
