Resant voltage stabilizers are devices that ensure the constancy of the current coming from the electric network. Due to this, volatile devices receive protection against failure. Stabilizers work equally effectively with high or prohibitively low voltage.
In addition, the devices provide fire safety, preventing overheating of the wires and failure of the insulation during sudden voltage surges.
Resant's stabilizers, the consumer reviews of which are completely favorable, have appeared on the market for quite some time. In general, the first devices of this type with an electromagnetic principle of operation have been used for more than half a century.
These devices were distinguished by large dimensions, low overload capacity and considerable weight. Modern electromagnetic or electronic stabilizers "Resanta" are characterized by a relatively low weight, stabilization accuracy and compact size.
Electromechanical stabilizers "Resanta"
Customer reviews indicate the effectiveness of these devices. They operate on the basis of an automatic transformer with switchable taps. In essence, the apparatus is an ordinary coil having many turns of copper wire. The most important element of the device is an electromagnetic mechanism equipped with a slider.
When the voltage decreases, the slider moves upwards along the taps until everything comes back to normal. With increasing load, everything happens the other way around. A graphite brush is used as a current collector. Resant stabilizers, reviews of which speak of them as reliable devices, support the output voltage with a deviation of no more than 2 percent, making its smooth adjustment.
In addition, in many models of devices two graphite brushes are provided at once. This design feature significantly increases the contact area, and this allows you to quickly adjust the voltage. Also, powerful devices of more than 30 kW are understaffed with another transformer. Such models have increased overload capacity and low noise level when used.
Electronic stabilizers "Resanta"
Reviews about this variety of devices are also positive. These devices are often called discrete, since the input voltage is adjusted in steps. Autotransformers are also used in their design. Unlike electromechanical devices, these devices use semiconductors or relays, rather than graphite brushes.
The accuracy of electronic stabilizers is slightly lower, the deviation is about 10 percent. However, this is not critical, since for many household appliances such power surges are permissible. Thus, Resant stabilizers reliably protect devices with electric motors, for example, refrigerators, stoves or pumps.
The main advantage of electronic voltage balancers is that in their design there are no moving mechanical elements, which ensures long-term operation of these devices.
