MDT AKI-1216.04 KNX Switch Actuator, 12-Channel, 12 TE DIN Rail, 16/20 A, 230 V AC, Capacitive Load 200 µF

The MDT AKI-1216.04 is a 12-channel KNX switch actuator designed for high inrush currents, handling up to 200 µF capacitive load per channel. Each of the 12 potential-free outputs switches up to 20 A resistive or 16 A capacitive at 230 V AC, making it suitable for demanding industrial and building automation tasks.

Advantages

With a compact 12 TE (216 mm) DIN rail housing, this actuator saves space while providing independent manual operation and LED status indication for each channel. The AgSnO2 contacts ensure reliable switching even at low currents down to 10 mA.

Suitable for

• Switching lighting circuits with high inrush currents (LED drivers, fluorescent ballasts)
• Controlling capacitive loads up to 200 µF per channel
