Toroidal Transformer, EI Laminated Transformer

Ouli EI laminated automatic door transformer are widely used in sliding, swinging, revolving door system, which design and test as IEC 61000, UL5085, enclosure protection need customize as requirements.

Ouli EI laminated current transformer is used to convert the large AC current into a certain proportion of small current for measurement and relay protection. The current transformer is composed of a closed core and windings. It has a few primary winding turns, which are stringed in the line of the current to be measured, so it often has the entire current of the line flowing. "

The inverter technology used in UPS design is based on silicon control rectifier/thyristor, which generates sine wave output through significant filtering. The power device will not turn off when DC power is supplied, and since the switching speed of the power device is slow, a transformer is needed to generate the required waveform.

Ouli EI laminated Inverter transformers are widely used in air conditioners, computers, washing machines, range hoods, refrigerators, video recorders, massagers, fans, home theaters, electric grinding wheels, power tools, sewing machines, lighting, etc.

Ouli EI laminated power step up/down transformer are widely used in various civil and industrial power buck-boost equipment. It is a transformer that achieves the voltage required by the equipment through voltage conversion.

Ouli EI laminated auto transformers are used in occasions where primary and secondary isolation are not required, and have the advantages of small size, less cost and high efficiency, such as AC manual rotating voltage regulators, transformers in small household AC voltage stablizer, three-phase motor auto starter panel, etc.,

Ouli EI laminated elevator transformers are widely used for the power supply of the safety lighting in the elevator and escalator, as well as the power supply of the board in the control panel, the power supply of the floor display and the button, and the power supply of the safety circuit, etc.

Ouli EI laminated safety isolation transformer are widely used in various UPS, audio, medical, lighting, automatic control, telecommunication, instruments equipment. it has function of anti-interference effect, impedance transformation, stabilizing the system voltage, preventing system grounding and reduce short-circuit current

Ouli EI laminated control transformer are widely used in various civil and industrial power control equipment. It is a transformer that to reduce supply voltages to control circuits, it has the ability to handle high in-rush currents that occur when electromagnetic components are energized, without sacrificing the required stable output voltage.
