The two port DSF series has been specifically designed for process control applications to protect the switched mode power supply units on devices such as PLC controllers, SCADA systems and motor controllers. The 30V unit is suitable for 12V and 24Vac/dc signaling and control systems.

The 6A DSF series incorporates a space efficient, low pass, series filter which provides attenuation to high frequency interference.


  • In-line series protection
  • EMI/RFI noise filtering protects against industrial electrical noise
  • Compact design fits into motor control and equipment panels
  • Three modes of protection: L-N, L-PE and N-PE
  • DIN rail mount provides simple installation
  • LED power indicator
