The wide range of HR transformers cover all the applications: pimaries of 115 V, 230 V, 380 V or doubles fo 115 V and secondaries of 4,5V to 24V simples, doubles or center tapped. With power between 0.35 VA to 20VA and for ambient temperatures about 40° C or 70° C and termic classes B or F on demand. Types and features \| Series index \| Searcher \| Technical information
	Toroidal transformers HR toroidal transformers are specially indicated for reduced space applications and low magnetic radiation. Its easy assembling process is one of its main characteristics. HR toroidal transformers standard range goes from 20VA to 3000VA. Its secondary dual configuration and its extensive voltage range allow you to arrange any voltage you may need by means of series of parallel assembling. Its compact constitution allows volume and weight reduction close to the 50% with regard to type EI conventional transformers. Types and features \| Series index \| Search
	Conventional transfomers HR conventional transformers in their diferent configuration of secondary simple, dual secondary or center tapped are the perfect version for its assembling in chassis and metallic boxes. HR technology managed to improve considerably this classic product: optimizing its energy yield, improving the transformer's issolation, and increasing its reliability notably. The standard range goes from 2.5VA to 18VA and the primary is the center tapped type (125v-220v) and the secondary can be: simple, dual, center tapped for 4.5v - 6v - 7.5V - 9v - 12v - 15v - 18v -24v voltages.

	Switch mode power supply Switch Mode Power Supply (SMPS, Electronics transformers) is a low cost regulated flyback power supply, based in a design that directly replaces multiples unregulated linear Power Supplies designs. The Electronic transformer has an extremely no-load low consumption, high efficiency and advanced safety features like over-voltage, over-current and thermal protection. Our designs use the same format of encapsulated transformers, so it is suitable to use in the same PCB space. Worldwide universal input, several standard single or multiple output voltages in different case formats. Series index
	Power inverters Also so called inverter or ondulator, is an electronic circuit used to turn direct current (DC) into alternating current (AC). The function of an inverter is to change the voltage of entry of direct current (it normally comes from a battery of 12 or 24 Vdc) to an alternate voltage of exit (normally tension of network (net) 110 or 230 Vac). The inverters are in the habit of being composed of an oscillator that controls a transistor wich is used to interrupt the constant tension of entry and to generate a square wave. This square wave feeds a transformer that adapts the tension level wiched in the exit and a final filter smooth the waveform making it very similar to a pure sine wave. It is also possible to generate modified sine wave, wich is generated from three points: one positive, the negative one and one to ground. Modified since wave inverters can cause less efficiency especially when working with inductive loads. Types and features \| Series index \| Technical information
	Chargers and adapters Universal input voltage chargers covering from 3.5W to 7.5W With the technology advances, the use of the switch mode power supplies have become essential in equipment with a high level of sophistication, very tolerant to over-voltages, sudden changes of supply voltage, over-currents, noise and so on. This type of regulated switch mode power supplies guarantees an equipment supply voltage of great quality. Series index
