Split Bobbin Printed Circuit

SplitZtran SZ-24 (24VAC Input)

Product Features

  • Single Primary - 24V, 50/60Hz
  • High isolation - 2500Vrms hipot
  • Low capacitive coupling - no electrostatic shield needed
  • PC pins for direct insertion in PC boards
  • Class B insulation - 130°C
  • Applications include HVAC-R Instrumentation and low-input voltage
  • Designed to meet UL/CSA


The SplitZtran is the most compact printed circuit mount power transformer requiring minimum surface area for the VA rating. The split bobbin (three flange) design allows the primary and secondary to be wound non-concentrically ie, side by side rather than one over the other. This assures high isolation and capacitive coupling between the windings, eliminating the need for electrostatic shield.

Applications

The SplitZtran is ideal for critical surface area PC board designs. Applications include

  •     Low input voltage (e.g. 24V, custom 12V input also available)
  •     HVAC-R instrumentation
  •     Low voltage/high isolation circuits (e.g. power supplies)
