Kemo M203 Master-Slave Switch 230 V AC Adjustable

The Kemo M203 is an adjustable Master-Slave switch that enables intelligent control of electrical devices. When the "master" device is turned on, the module detects power consumption and automatically activates the "slave" devices. The M203 supports a maximum total load of 3680 W (16 A), with a maximum "slave" power of 2300 W (10 A). The activation sensitivity is adjustable from 5 to 60 W, allowing the activation threshold to be precisely configured. This device is ideal for the automation of offices, laboratories, home theater systems and other configurations where synchronous management of multiple appliances is required.

Installation is simple and safe, with overload and short circuit protection. To ensure optimal heat dissipation, the module features an aluminum base that can be connected to an additional cooling surface for loads exceeding 500W. It also features a two-color LED to indicate operating status: green for ready and red for slave activation.
