  1. Products for 60 Hz power supply frequency are also available on request.
  2. Above 300 A requirement, multiple units will be connected in parallel. Up to 40 units can be connected in parallel. Contact Amtech for any other requirement / more details.
  3. The -2 is for 230 V, - 4 is for 415 V and -5 is for 600 V input supply.
  4. The - 1N in the part number defines neutral current capacity equal to the rated filter current; For higher neutral current rating, consult Amtech. This is only applicable for the 3-Phase, 4-Wire system.
  5. Minimum 3 % line reactor is required in series with higher di/dt load.
  6. All performance specifications are valid at nominal ratings.
