Inverter Transformer
Description:
Inverter transformer is a kind of work in DC to AC transformer under the module
Used in solar energy,vehicle power supply system, uninterruptible power supply, etc.
Flyback topology structure
Operate at 57kHz with 20~55 VDC input
Rectified sine wave output
Maximum Power:100W
Hipot voltage: 3000Vrms,one minute isolation primary to secondary
1500Vrms,one minute isolation windings to core
Custom designs available
Operating temperature range: -40℃ to +85℃
Storage temperature range: -40℃ to +85℃
RoHS Compliant version is available

① L(NOM)=Nominal Inductance is for pri winding, measured at 150KHz,1.0Vrms
② Leakage inductance measured at 150KHz,1.0Vrms between Pri other pins shorted
③ DCR for the primary is with windings connected in parallel
④ Ipk is the peak current drawn at minimum input voltage
