Why does SUNTEK keep its parameters even at 50 degrees?

Ambient temperature is a very important parameter that must be taken into account when developing new models of voltage stabilizers. A few years ago, the company's developers SUNTEK faced the question of how to make the voltage stabilizer work in winter in cold countries, where the temperature drops to minus 30 degrees. This problem was solved by choosing parts with a high level of frost resistance and a special contact coating that does not allow "sticking" in the cold.

Our main office and warehouse is now located in the UAE, where, as you understand, the ambient temperature is, on the contrary, high. Customers from neighboring countries and African countries are concerned about the operation of voltage stabilizers at high temperatures.

So, the first step that we took was to check the current-voltage characteristics of our elements on the control board. I must say that we are lucky here, because by installing more expensive models for low temperature, we automatically got a solution for high temperature (since these elements have extended characteristics, they retained their parameters from minus 30 degrees to 60 degrees).

The second step was the fight against high temperature due to additional elements. In powerful models, we strengthened the radiators for the brushes and, in addition, installed forced cooling directly on the radiators, as in the photo (after all, as you know, at the time of current collection, the temperature rises very much).

In the next step, we placed the elements on the control board away from each other, and equipped the transistors with individual radiators. This allows us to distribute heat rather than store it. In addition, in servomotor models in a hinged case, we divided the brush into two, thereby now we take current from two places, thereby again distributing heat, which allows each brush to be heated less individually.

In SUNTEK three-phase voltage stabilizer models, we moved our control boards forward so that the heat from the coil does not interact with the control board, but rather is dissipated.

Finally, the last and important step was that we increased the thickness of the wire and the varnish on the coil. Thus, we minimize the air space between the turns, thereby protecting against sparks and, as a result, a decrease in temperature.

Now SUNTEK voltage stabilizers are ready to work even in the most difficult temperature conditions. In addition, we ask you, our customers and partners, do not install a 10KVA voltage regulator for a 10KVA load, install a voltage regulator with a small power margin, at least let 20-30% be free (for a 10KVA load, install it at 12KVA or 15KVA), although it is iron, it is also alive.
