1W Medical DC DC converter H_S-1WR2 Series
Description
H_S-1WR2 series meet reinforced insulation requirements.They are specially designed for applications where require compact size,high isolation,low isolation capacitor and low leakage current power.They are widely used in medical,electricity,IGBT driver and so on.They are suitable for:
1.Where the voltage of the input power supply is stable(voltage variation:±10%Vin);
2.Where isolation is necessary between input and output (isolation voltage ≤4200VAC or 6000VDC); 3.Where do not has high requirement of line regulation and the ripple&noise of the output voltage; Such as:Medical collection and solation,High voltage collection circuit,IGBT-driven circuits,etc.
