HIGH CURRENT TOROIDAL CORE CHOKES

In the broad product field of winding materials, particularly in the special area "toroidal core chokes".

CALTRON is in a position to develop and even to produce components for applications with high nominai currents, high nominai output power.

Suitable toroidal winding machines and traction machines, so-called "pull winders",
help to make the execution of these types of products possible.
In addition to our standard program, we can offer components for the following fields of application:
  • - Frequency converters
  • - UPS systems
  • - Motor drives
  • - Switched-mode power supplies
We specialise in the following products:

Compensated multiple chokes;
P+N; 3P; 3P+N

Nominal current :up to 100Amp.

All of these special chokes are developed and produced in accordance with customer wishes. They are frequently recommended in an open construction in horizontal or vertical version. We shall gladly study your component problem and prepara an optimum offer at short time. CALTRON is able to contribute well over 20 years of engineering experience in this field.

HIGH FREQUENCY POWER TRANSFORMERS

Compared with conventional 50/60 Hz mains transformers, high frequency power transformers offer the following advantages:
  • - Reduced volume and weight
  • - High efficiency degree
Power transformers are used in many modem power supply applications.
Specifically switchings such as Flyback, Forward, Push-Pull and AC/DC or DC/DC converters can be named as main areas of use. Ferrite materials in various forms are used, depending on the application these can be toroidal or EE/EF/ETD and EFD standard cores.

  • - EE/EF cores are the types most widely used in very high volumes
  • - ETD cores are preferred if simple winding technology and a compact structure are required
  • - EFD cores are used tor extremely flat power transformer structures
- Power transformer output :up to 1.000 Watt
- Operating frequency :up to 1 MHz (depending on the ferrite materiai)
- lsolation strenght :up to 4.000 V AC/50Hz /1 min.
- Operating temperature :-25°C + +85°C
- lnflammability :as per UL94V-O
Depending on the core form a vertical or horizontal structure is possible. The windings are wound with copper wire, HF stranded wire or triple isolated wire depending on the requirements. The safety standard conforms to EN 60950. We shall be pleased to develop and produce your special power transformer in accordance with your specifications. CALTRON is in a position to prepara a prototype with data sheet in the shortest of time.
