S 8

Problem

Frequency converters have a bad return voltage at their outputs (u,v,w), which occurs when the connected motor acts as a generator. S-8 serves as a protective device against this voltage.

Solution

S-8 is a device that has 8 input channels that are activated by the arrival of a nominal voltage of 24VDC (18-36VDC). Each of these channels can be used either individually or all at once. When this voltage of 24VDC appears at the input, the output channel of 220V AC / 8A is switched on/off. In this way, the S-8 acts as a relay. Its advantage is that there are NO mechanical relays on it, but everything overlaps electronically. It also has additional filters on its outputs that enable it to be used when switching the power supply for LEDs or their chains.

Application

a) SMART HOUSES – can be placed on the main board of the entire management of such a building or house and even in the living room, because no noise from switching mechanical relays is heard

b) Autoclave – medical device for sterilization of metal surgical accessories – S-8 serves as an interface for its 24VDC pump. So it can be replaced with a 220VAC pump

c) On the road – for different flickering warning lights for drivers (roadworks, broken traffic lights, etc.)

d) For electric motors of different purposes where reliable electric relays are needed

e) In hotels – when they have automatic systems where 24VDC motors are necessary. Then the S-8 can be used for interfaces to the 220VAC motor, which are much more reliable.
