EMI Class B and Power Factor Correction

The main improvements provided by the S8JX-P models are Harmonic current suppression/PFC (Power Factor Correction) and EMI EN55011 Class B compliant. In addition, further functionalities have been implemented (applies only to 300 and 600w models).


  • Remote Sensing, to compensate for voltage drops on the load lines.
  • Remote Control, using an external signal allows to turn the output ON and OFF without removing the input voltage.
  • Alarm Output, informing about PS errors, such as fan failure or insufficient voltage.
  • Conforms to SEMI F47 Compatibility for 300-W and 600-W Models (For 200-V Input).

The S8JX-P family is available for 5, 12, 24 and 48VDC output voltages (15VDC is also available for S8JX-G 15W and 35W). The range of power ratings covers 50W, 100W, 150W, 300W and 600W with all the output voltages available through the whole range.
