ST/DST Series - Power Transformer

ST/DST PC Board Transformer uses a "split bobbin" which allows the primary and secondary to be wound nonconcentrically (ie, side by side rather than one over the other). This has the advantage of cost savings and superior performance.

Features :
-High insulation 2500V RMS Hipot
-Class B insulation 130 degree celcius
-Low Capacitive coupling - no electrostatic shield is necessary
-Less manufacturing time - no cross over of primary and secondary leads
-Each transformer is available with single 115V or dual 115/230V primaries. In addition, secondaries are split so that they can be series or parallel connected. Variations can be made to meet special needs.
