A range of Westack & Westack Lite Assembly modules can either incorporate single or dual devices and allow the building of:

  • Single phase diode and thyristor bridges
  • Three phase diode and thyristor bridges
  • Six phase diode and thyristor bridges

Custom built assembly can be provided when a standard solution is not available. Cooling for each module section is provided by the use of a low noise 115/230 V ac fan which is protected against overloading by an integral thermal cut-out.

Surge suppression and fusing provides reliable and safe operation. Surge suppression (protecting the devices from voltage transients) and high speed fuses (to protect against short circuit) are available.

All plastic components are UL recognized and meet the requirements of the European Union Directive 2002/95/EC covering the restricted use of certain hazardous substances in electrical and electronic equipment.
