The PA200xNL series from Pulse Electronics are high isolation power transformers designed for basic and operational insulation applications. These transformers offer 1500Vrms isolation (380Vrms continuous) and are suitable for operating frequencies of 50kHz and up. They are available with basic insulation featuring 1.4mm creepage/clearance, or operational insulation. The maximum volt-sec rating limits peak flux density to 2800 Gauss in unipolar drive applications, with double this rating acceptable for bipolar drive applications. These transformers are RoHS-compliant, indicated by the "NL" suffix.
