This project is a 3-phase step-down transformer to power two high-temperature fans. It contains 3 single-phase transformers wired in a delta-wye configuration which drops the voltage to about 100V per phase to slow the fans down a bit.

Proposed Upgrade June 2011

The system is being upgraded to handle 4 fans. The power supply (transformer) box will be replaced by a 3-phase Variac

• ExpressSCH

  • Note: All switches, temperature controllers, and the variac will be mounted on the boxs front panel. All plugs, input cables, and fuses will be mounted on the rear panel.
  • Bill of Materials for Variac Box

Existing system as of May 2011
