Single phase isolating transformers are used as protection from electrocution of the users and for adjusting the voltage to the voltage required by the powered equipment.

These transformers are built in accordance with Safety Standards for transformers IEC 61558 and are used in electrical cabinets as a control transformer or for operation of electronic equipment in industrial machines.

These transformers supplies voltage, power, frequency and build to meet standards according to customers’ specifications.

The transformers are Class B 130ºC and are available with Class H 180ºC insulation system. These transformers are also available with UL Recognized certificates.

The toroidal transformer is one of the main products of Hulda Transformers, due to the growing demand for such transformers. The factory flagship product is characterized by compliance with IEC61558 standard, which makes it suitable for electronic equipment in a highly dense environment.

The toroidal transformer has the ability to transmit power with high efficiency and the power / volume ratio is superior to the standard transformers. Due to its structure, the magnetic flux is concentrated in the transformer body and has very small noise effect on the electronic components in its environment.

The manufacturing process is according to customer’s specifications for various voltages, frequencies, power rating and specific standards.

The transformers are Class B 130ºC and are available with Class H 180ºC insulation system. These transformers are also available with UL Recognized certificates.

Transformers suited to the requirements of hospitals are manufactured according to stringent standards: Reinforced insulation according to Standard VDE0551, IEC61558-2-15, IEC60601-1, galvanic isolated windings, low leakage current, thermocouple and static shield to be connected to monitoring system, current transformer, etc.

Hulda transformers, offers a product line for stabilizing the voltage to operate the amplifiers in the cable television distribution network. This product line offers:

• Power supply and voltage stabilizer 63V or 90V required to operate the line amplifiers, this power-supply excels at a very high efficiency (over 95%), pure sinusoidal voltage, high voltage stability, extremely low inrush current and a long problem free lifespan, etc..
• Voltage amplifier and stabilizer that allows the extension of the supply line to the amplifiers while automatically compensating the voltage drop along the supply lines.
• Special Voltage amplifier allows the cable network line to feed communication components in the 5G broadcast system.

Hulda transformers provides the R&D service to the customer according to an agreed specification, while optimizing the components to meet the requirements of the standard, the efficiency and the safe operation of the required product.

Hulda Transformers offers procurement services and the management of storage for standard raw materials as well as special materials according to the requirements of the customer.

The products that are in stock at the factory:
