Schematic
PL2983NL-1
Between the primary winding and output windings, between the primary winding and core, and between the output 1 winding and output 2 thru 4 windings, this part is
designed to comply with the spacing (creepage and clearance) and insulation requirements for reinforced insul ation up to a working voltage of 400VRMS per
IEC60664-1. The part is intended for equipment energized from a low voltage mains with rated impulse voltage up to 4000V. Clearances are adjusted for altitude up to
3000 meters. Parts are 100% HIPOT tested in production. All insulating materials meet or exceed flammability classification U L94V-0. Double insulated EMI band is
connected to PIN 7.
