HAMMOND PLATE TRANSFORMERS -
Expanded Data by LONDON POWER


High voltage windings for plate supplies, each centre-tapped. Units with 1kV or higher total voltage have leads through rubber grommets. 117V primaries only.

  • All specs AC except as noted. All specs absolute maximum
  • DC specs assume capacitive filter with full-wave solid-state rectification

• VATOTAL Maximum power throughput
• VTOTAL Total end-to-end winding voltage
• VLOW AC voltage between one end of winding and centre-tap; expected DC output and
  current rating using half-bridge full-wave rectification and capacitive filter
• VHIGH AC voltage of full winding; centre-tap not used, or, used to centre output capacitor
  voltage; expected DC output usinf full-bridge full-wave rectification and capacitive filter
• Mass Weight in pounds; old tabled value; most units are slightly lighter at the time of writing
