Switch Actuator MDT 20-channel AKS-2016.03 — 12TE, 16A, 230VAC, C-load

MDT switch actuator AKS-2016.03 is a 20-channel DIN-rail device designed for centralized switching in KNX installations. The unit occupies 12TE of DIN-rail space and provides independent control of twenty outputs. Each channel is rated for switching at 230VAC with a maximum continuous switching current of 16A and C-type load characteristics, making the actuator suitable for a range of lighting and small load applications in residential and commercial settings.

Advantages

The actuator consolidates control of multiple circuits into a single 12TE module, reducing panel space and simplifying wiring. With 20 independently switchable channels and a 16A per-channel rating, it supports high-density installations and can handle a variety of lighting types and small appliances. The device is intended for integration in KNX systems, offering reliable switching performance and consistent electrical characteristics for C-loads.

Suitable for

• Centralized lighting control in apartments, houses, or office spaces
• Switching socket circuits for small appliances and equipment
• Automation projects that require many independent outputs within limited DIN-rail space
• Commercial installations where multiple circuits must be managed from a KNX system

Key specifications

• Channels: 20 independent switching outputs
• Mounting: DIN-rail, occupying 12TE of width
• Nominal voltage: 230VAC
• Maximum switching current per channel: 16A (continuous)
• Load characteristic: C-type (suitable for inductive and resistive lighting loads within C-load specification)
• Intended use: centralized switch actuator for building automation (KNX)

How to use

Install the actuator on a standard DIN-rail inside the distribution board according to local electrical codes and the KNX system topology. Connect the line and load conductors to the corresponding output terminals and ensure proper neutral and protective earth connections where required. Integrate the device into the KNX project via the bus connection and configure each channel in the ETS or compatible engineering tool to match the desired switching functions and group addresses. Verify connections and perform functional tests before placing the circuit into regular operation.

Usage recommendations

Ensure that loads connected to each channel do not exceed the 16A rating and conform to C-load characteristics; for mixed or highly inductive loads, verify derating requirements and thermal constraints. Keep the device in a properly ventilated distribution enclosure and follow KNX and local installation standards for wiring, protection devices, and commissioning.
