The Kit purpose is the promotion of various kinds of applications where the AC switch is

controlled in ON/OFF full-phase mode. The switch control is based on the information push

button evaluated by the MCU.

As mentioned, the board software can easily be modified to final application requirements.

Here below is a list of possible applications that can be addressed:

●

Fridge

●

Breadmaker

●

Soy milk maker

●

Coffee machine

Additionally, the list of loads that can be controlled with this board is as follows:

●

Valves

●

Pumps

●

Door locks

●

Heating resistors up to 500 W

The added advantages of this board are:

●

Spark free operation

●

No EMI or acoustic noise

2.3

Operation principle

The board operation principle is based on MCU software. Implemented software features

are:

●

50/60 Hz detection implemented

●

Full wave operation (zero voltage turn-on of the switch) according to push button

action.

2.4

Operating conditions

The board operates in nominal line voltage 230 V in both 50/60 Hz power nets.

●

Line RMS voltage range: 197 to 264 V, 50 or 60 Hz

●

Operating ambient temperature 10 to 60 °C

●

Load power ranges (for 230 V RMS voltage)

–

OUT 1 controlled by ACS108-6SUF: 0 to 100 W

–

OUT 2 controlled by T1010H-6G: 100 to 500 W
