The ABB SV/S 30.160.1.1 KNX Power Supply generates and monitors the KNX system voltage (SELV) for a single bus line. Rated at 160 mA output at 30 V DC, it is the entry-level supply in the ABB SV/S 30 series — suited to small KNX lines with a limited number of sensors, inputs, and actuators.

An integrated choke decouples the bus line from the power supply output, which is essential for reliable KNX data transmission. The output is short-circuit and overload protected. Mains input accepts a wide range of 85 … 265 V AC, 50/60 Hz, and a two-colour LED indicates output and bus status at a glance.

Key Features — Line Power and Monitoring

Power Output

• 160 mA at 30 V DC: SELV output for one KNX line segment.
• Integrated choke: One built-in choke decouples the bus — no separate choke required.
• Protection: Short-circuit and overload protected output.
• Status LED: Two-colour indicator for output and communication status.

Installation

• 4 MW MDRC: 72 × 90 × 64.5 mm DIN-rail module.
• Wide mains input: 85 … 265 V AC, 50/60 Hz.
• Power loss: 4.4 W typical.

Applications and KNX Integration

• Small apartment or hotel room lines: Power a single line with a few sensors, binary inputs, and switching actuators.
• Secondary segments: Supply a sub-line behind a line coupler when total load stays within 160 mA.
• ETS monitoring: Import the shared .knxprod application (Downloads) to read power-supply diagnostics on the bus.
• Segment coupling: Combine with a LK/S 4.2 KNX Line Coupler when splitting lines; each segment needs its own SV/S supply.

Choosing SV/S 30 Power Supplies

Select capacity based on calculated bus current (typically 10 mA per device plus actuator loads). For medium lines, choose the SV/S 30.320.1.1 KNX Power Supply 320 mA. For large main lines or dual-output capability, choose the SV/S 30.640.3.1 KNX Power Supply 640 mA. IP routers such as the IPR/S3.1.1 KNX IP Router require a separate 12 … 30 V DC auxiliary feed from the same panel supply.
