SANHE EE19 High Voltage Switching Power Supply Transformer For Printer

Short Description:

Model NO. :SH-EE19

It is a high-voltage switching power supply transformer used in printer. It provides necessary driving voltage and negative high voltage for the power supply. Multi-slot structure with special slot design to fit for laps and ways of winding can share the high output voltage, and ensure sufficient safety distance between the lead and the winding to avoid corona and high voltage breakdown.
