ELECTRONIC TRANSFORMER

ELECTRONIC TRANSFORMERA power transformer is to convert alternating current of one voltage to alternating current of another voltage at a constant frequency. The device in the normal “classic” transformer all know from school physics lessons. The principle of operation is based on electromagnetic induction. In the primary winding under the action of tension in the core induces a magnetic flux proportional to this voltage, which, in turn, an electromotive force of self-induction (EMF) in the secondary windings is directly proportional to the number of turns of these windings.

Electronic transformer (ET) and arranged differently, and the principle of its action is quite different. In fact, ET is a switching power supply — inverter voltage with electronic protection against short circuit, overload and excessive heating of the elements. All energy-saving lamps, lamps, lamps, fluorescent lights, illumination of aquariums and other similar devices are equipped with a FLOOR probe.

SOURCE THREE “STREAM”

SOURCE THREE For connecting various electronic and household devices designed for a constant voltage of 9, 12 or 15 V, requires adapter (the adapter from the network 220V). Usually every device it sells.
Meanwhile, there are many devices without adapters, but in some time the latter may be useful, for example, to power portable electric drill (screwdriver), which has lost energy output of the battery, or receiver, whose “exhausted”, or other similar event.
It must be sufficiently powerful and reliable power source, with automatic protection of output (triggered by a short circuit in the load) with the universality (outstanding various constant voltage) for use in the home.

SECURITY ALARM

SECURITY ALARMThis is a safety alarm device (SLD) is designed to automatically alarm (electrozone) in the case of penetration of unauthorized persons in the protected object — an apartment, dacha, garage. It is more immunity and no false positives. The unit is powered by 12-volt battery GB1 of the eight cells that consume standby current less than 5 mA.
