Patent number: 11289895Abstract: A protective device includes a first fuse circuit, an overvoltage protection circuit, and a second fuse circuit. The first fuse circuit interrupts a flow of a line current from a voltage terminal to the electrical load when an intensity of the line current reaches a first current intensity limit value. The overvoltage protection circuit electrically connects poles of the voltage terminal when a first voltage limit value of a voltage is reached on the first fuse circuit to force the line current to reach the first current intensity limit value. The second fuse circuit activates the overvoltage protection circuit when a second voltage limit value of a voltage on the second fuse circuit is reached to electrically connect the poles of the voltage terminal. The second voltage limit value is based at least in part on a nominal voltage of the electrical load.Type: GrantFiled: May 22, 2019Date of Patent: March 29, 2022Assignee: Phoenix Contact GmbH & Co. KGInventor: Jörg Blanke

Patent number: 9711271Abstract: A planar transformer is provided, which comprises a plate-shaped conductor substrate with integrated primary winding, secondary winding and coupling winding. The conductor substrate has pairs of recesses, and a respective two-part ferromagnetic core having yoke legs is inserted through each pair of recesses. One leg of each core is surrounded by the primary winding or the secondary winding, while the coupling winding is looped around the remaining legs of the cores. At least a minimum total isolation separation distance made up of partial isolation separation distances between the coupling winding and adjacent yoke legs or adjacent windings is maintained for electrical isolation between the primary winding and the secondary winding.Type: GrantFiled: November 12, 2013Date of Patent: July 18, 2017Assignee: PHOENIX CONTACT GMBH & CO.

Patent number: 9300218Abstract: The invention relates to a signal (feed) separator for dead-zero or live-zero measurement signals. The signal (feed) separator has a primary-side (feed) input, a secondary-side output, a direct-current transformer for transferring primary-side measurement input current, an output stage for providing a secondary-side measurement output current, and an auxiliary energy feed-in for supplying the primary side and for supplying the secondary side. The auxiliary voltage of the auxiliary energy feed-in is controlled on the secondary side by a control device with the aid of a measuring device in such a way that the power loss of the output stage is substantially independent of a load connected in the operating state.Type: GrantFiled: December 20, 2011Date of Patent: March 29, 2016Assignee: PHOENIX CONTACT GMBH & CO.

Publication number: 20110043319Abstract: A pulse transformer having a primary core (1) with a primary winding (2), a first secondary core (3) with a first secondary winding (4) and a second secondary core (5) with a second secondary winding (6), wherein the primary core (1), the first secondary core (3) and the second secondary core (5) are connected to each other by way of a squirrel-cage winding (7). In accordance with the invention, a transformer current converter is cited that, as a doubler, provides an input signal at two outputs in such a manner that—with an equal number of turns on the first secondary winding (4) and the second secondary winding (6)—the same signal is available at both outputs.Type: ApplicationFiled: August 12, 2010Publication date: February 24, 2011Applicant: PHOENIX CONTACT GMBH & CO.

Patent number: 7667563Abstract: The present invention relates in general to the field of interface technology. Electronic components, such as modular converters for measurement control and regulation technology, in particular isolation amplifiers, are known from interface technology. Such isolation amplifiers can be used for galvanic separation, conversion, amplification and filtering of standard, normal signals and for matching analog signals. These isolation amplifiers are galvanically separated from one another in the input, output and supply circuits. According to the invention, a separate component of a transformer is integrated for separation into a circuit board of an isolation amplifier with the aid of SMD mounting technology, wherein the transformer contains a combination of inductive components, consisting of a magnetic core and a winding, and a substrate which contains internal printed conductors that form planar short-circuit windings.Type: GrantFiled: August 30, 2006Date of Patent: February 23, 2010Assignee: Phoenix Contact GmbH & Co.
