Power adapter/inverter ABB SV/S30.640.3.1 — 30 V output, 85–265 V input, grey, plastic housing (72×64.5×90 mm)

ABB SV/S30.640.3.1 is a compact KNX power supply that generates and monitors the KNX system voltage (SELV). The device provides a stabilized DC output and includes an integrated choke to decouple the bus line from the power supply. The output is protected against short-circuit and overload and features a two-colour LED to indicate output status. The unit accepts a wide input voltage range of 85–265 V AC at 50/60 Hz and is housed in a grey plastic enclosure measuring 72 × 64.5 × 90 mm.

Advantages

The power supply offers a monitored KNX output with built-in short-circuit and overload protection for reliable operation. An integrated choke isolates the bus line to reduce interference and simplify installation. The two-colour status LED provides a clear visual indication of device output state. Model SV/S 30.640.3.1 includes an additional 30 V DC output, also protected against short-circuit and overload, which can be used to feed an additional bus line when combined with a separate choke.

Suitable for (tasks / use cases)

• Supplying KNX bus lines in building automation systems
• Powering devices that require a stabilized DC KNX supply
• Industrial or commercial installations needing a wide-input voltage power source

How to use

Install the power supply in accordance with KNX and local electrical installation standards. Connect the AC input to a suitable 85–265 V AC supply and connect the KNX bus line to the monitored KNX output. If an additional bus line is required, use the 30 V DC protected output together with a separate choke to decouple that bus line. Verify correct wiring and power the unit; check the two-colour LED to confirm output status.

Recommendations

Ensure installation and maintenance are performed by qualified personnel. Use the additional 30 V DC output only with an appropriate choke and within the device’s rated limits. Observe manufacturer guidelines and local regulations for grounding, wiring, and protection to maintain SELV compliance and safe operation.
