APPLICATION
Smart electrical switches are used to replace conventional mechanical switches. With a compact design of 72mm * 116mm, it is compatible with most wall mounted plastic bases on the Vietnamese market (usually using SINO plastic bases). Just replace with old equipment and 3 minutes of installation to use.
Due to the variety of equipment in each family, Stahomes products allow the choice of RELAY (EH-KDIO-4R) or TRIAC (EH-KDIO-4T) power components. Currently, most families use 3-color (tri-color) LED lights as a lighting device that both saves electricity and makes the room more luxurious. However, this type of LED usually has a very high starting current, if each control line has about 6 LEDs of 15W-18W type, the 10A high current relays sometimes still stick to the contacts causing the control to turn off but the device is still on. . Stahomes has overcome that drawback by using the Triac output. Triac is a non-contact switching power electronic component, so it does not generate sparks and prolongs life.

So how to choose the right type of power components to use, better TRIAC or RELAY? Depending on the type of device, there will be an appropriate answer. Stahomes equipment uses a TRIAC type that allows a current of up to 24A, but due to the small design space, it is not possible to install a heat sink, so it is only recommended to use a device with a maximum current of 5A to avoid generating heat for the device. Therefore, when you need to control high-current equipment such as air conditioners, water heaters, refrigerators, you should choose RELAY type and ordinary devices such as lights, fans ... then choose TRIAC type to increase the number of switching times. , does not generate sparks, so the control is safer.

Because the control model Stahomes is very flexible and innovative, one device can be controlled in many different positions, so the control switch product has only 4 buttons. With 4 buttons on one controller, it makes the control more convenient and easier than other products. For example, when you are in the kitchen about to go upstairs, the controller in the kitchen can turn off the lights in the living room, yard lights ... without having to go to the place to turn it off. That's why the number of control keys of Stahomes is never superfluous.

In addition, the product also allows the choice of using 1- or 2-wire power, making it easy and quick to replace old switches to new devices without having to punch walls or renovate the house.
