U1From AC to DC

Mains in, clean power out.

  1. 01AC inputMains power enters through the fuse.
  2. 02Noise filterChokes and capacitors keep electrical noise in and out of the line.
  3. 03Rectifier & PFCAC becomes high-voltage DC, stored in the bulk capacitors.
  4. 04TransformerFast switching through the transformer steps the voltage down safely.
  5. 05DC outputSmoothed, regulated DC leaves for the LEDs or the machine.

Illustrative: a generic SMPS board, not a specific Union model.
