Power Electronics Components

Power Electronics

Over a period of fourty years, Fastron has established a leading position servicing the Australian, New Zealand and Asian markets with High Power Semiconductors comprising Thyristors, Diodes, Bridges, IGBT's and Solid State Relays in both discrete, isolated module and multi-chip types. 

Lower Power Semiconductors and a range of PCB mount components such as Diodes, Bridges, IGBT's, Mosfets, Pulse Transformers, Filters, Chokes, Varistors, Solid State Relays, and Capacitors.

In addition, we offer  wide range of Electrical Measurement products including , Capacitors, Hall Effect Current and Voltage Sensors, Rogowski Coils, Current Transformers, High Precision Medical Grade Current Sensors, and Custom made AC or DC Current Transducers with or without Alarm Outputs, and signal conditioners to suit almost any process application.

Fastron also specialise in supplying a range of standard and custom engineered products including Semiconductor Heat Sink Assemblies, Semiconductor Protection Fuses (Trent), Thyristor (SCR) Power Controllers (OZtherm), Power Factor Controllers, Smart Capacitor Banks, and other related components, products and services. 

For more advanced processing requirements and applications requiring interfacing with BMS, or other communication/management systems we also offer German designed Advanced Energy Thyro Series SCR Power Controllers

Custom products such as special purpose solid state contactors/controllers and isolated, AC/DC current and voltage transducers can also be designed, developed and manufactured to your specification supported by our in-house CAD-CAM and PCB design facility. For more information please refer to our Engineering and Site Services section on our website.
