LOW PROFILE, PLUG IN POWER TRANSFORMERS
 

3S Industries Low Profile power transformers is ideal for low height, critical pc board power applications in semi-conductor control and instrumentation. This is accomplisheed by the dual bobbin construction. The insulation system results in high isolation between primary and secondary windings and from either to the core. Hipot test is on this transformers 1500VAC RMS.

All 3S industries transformers are 100% tested for turns ratio, exciting current, phasing & hipot.
