Model and control functions

Parameter	Details
Model identity	Manufacturer ordering code: KAA-4R4V-10S.
Supply method	Powered by the EIB/KNX bus; no additional power supply is required.
Relay arrangement	Four independent latching relays with four dimming-control channels. Select the required switching, dimming or shutter application in ETS.
Rated channel selection	10 A per channel. Observe the load-category, total-current and inrush limits below.
Configuration and manual operation	Configure the application with ETS. Panel buttons provide manual operation and status indication. Time and scene functions are programmable.
KNX Data Secure	The device certificate attached to the unit is required for the first secure configuration. After commissioning, remove it from the device as recommended and store it securely. Use a compatible application database and specialist KNX commissioning knowledge.
Dimming interface	Four DC 0(1)–10 V passive current-sinking outputs for compatible LED drivers or electronic ballasts. This is a control interface, not an LED load power supply.
Dimming response	Linear or logarithmic dimming curves are selectable in ETS. Each channel has a green status LED.
Communication functions	Central manual enable, switching, absolute dimming and operation status; channel switching/status, relative and absolute dimming, scenes, automatic functions, blocking and staircase-light functions. The communication-object table also provides prewarning and permanent ON; use the application database for the applicable objects and flags.

Electrical and switching ratings

Parameter	Details
KNX bus supply	21–31 VDC.
Bus current and power	Below 14 mA; below 250 mW.
Relay output rating	230 VAC, 50 Hz; 10 A ohmic load per relay. Each relay is independent and potential-free.
Capacitive load	220 µF; the catalog identifies a Notified Body test report.
Maximum inrush current	400 A for a maximum 200 µs, or 80 A for a maximum 20 ms.
Load categories	EN 60947-4-1: AC1 (cos φ = 0.8) 10 A; AC5a (cos φ = 0.45) 8 A; AC5b 10 A.
Maximum total current	40 A for the actuator; the per-channel rating does not override this aggregate limit.
Service life	Mechanical: more than 10⁶ cycles. Electrical endurance EN 60669-1 section 19.1: 4 × 10⁴ cycles; fluorescent lamp (AX), section 19.2: 10⁴ cycles. The specified electrical tests have a Notified Body test report.
Shutter outputs	Two paired shutter outputs.
Dimming output limit	Four passive 0–10 V control outputs, maximum 50 mA sinking current per output.
Dimming cable length	Up to 100 m at full control load with 1.5 mm² cable.
Control-device quantity	Up to 500 drivers per dimming-control channel only when each driver sources 0.1 mA. Actual allowable quantity also depends on the installation, including total cable length. This is separate from relay switching capacity.

Standards and reliability

Parameter	Details
Safety model	KAA-4R4V-10S
Safety standards	BS EN/EN 50491-3; BS EN/EN 60669-1, -2-1 and -2-5; EAC TP TC 004. The catalog identifies a Notified Body test report for the marked tests.
EMC emissions and immunity	BS EN/EN 50491-5-1, -5-2 and -5-3; BS EN/EN 50090-2-2; BS EN/EN 60669-2-1 and -2-5; BS EN/EN 63044-5-1, -5-2 and -5-3; EAC TP TC 020.
Withstand voltage	Between switching and SELV control circuits: 3.5 kVAC.
MTBF reference	686,900 hours minimum per Telcordia SR-332; 302,300 hours minimum per MIL-HDBK-217F at 25°C. Calculated reliability references, not guaranteed service life.
Specification conditions	Unless otherwise stated, parameters are measured at 230 VAC input, rated load and 25°C ambient temperature.
Manufacturer warranty reference	The catalog states a 3-year manufacturer warranty, subject to its applicable terms.

Manufacturer installation instructions

Parameter	Details
Terminal torque discrepancy	The current catalogue states 0.8 Nm, while the instruction manual recommends 5 kgf-cm (4.4 lb-in) at the screw terminals. These values differ. Confirm the instructions for the supplied hardware revision with MEAN WELL before tightening.
KNX terminal and cable layout	Use 0.6-0.8 mm solid-wire diameter at the KNX bus terminal and strip 5 mm. The manual lists 350 m maximum from the bus supply to the furthest device, 700 m between devices and 1000 m total bus-line segments; the stated maximum 256 devices remains subject to actual system power and topology.
Secure commissioning	For KNX Data Secure, use ETS5 version 5.5.0 or later, the device-specific FDSK from its label and the required project security configuration. The manual also allows unsecured operation when deliberately configured; secure capability alone does not mean the installed system is operating securely.
Relay and dimming terminal preparation	The manual specifies 0.5-4.0 mm2 solid or 0.5-2.5 mm2 stranded conductors (12-26 AWG), stripped 6.5 mm, for the relay and dimming screw terminals, with a 3 mm slotted screwdriver. Confirm the applicable terminal torque separately.
Passive dimming interface	The DC 0(1)-10 V dimming outputs are passive. Use the appropriate wiring diagram for a compatible 1-10 V or 0-10 V LED driver. A non-dimmable driver can use relay switching only; a shutter motor requires its separate relay wiring arrangement.
