Un = 3×400 V
fn = 50 Hz
fr = 250 Hz
Three-phase mains filter
Description
Information:
- Modern power electronics are feeding more and more interference pulses back into the grid. To reduce or eliminate this conducted interference (harmonics, EMC), a mains filter is also connected upstream of the frequency converter. This is particularly important with regard to the CE mark, as the CE mark of a machine also confirms its EMC compatibility.
- Chokes are vacuum impregnated with cast resin varnish to reduce humming and to increase insulation.
- We use high-quality choke insulation materials for insulation class T40/F
- Connections as terminals or copper rails, depending on the current.
- All sine filters are dimensioned by computer, manufactured with CNC machines, piece-tested including a high-voltage insulation test with several 1000V.
- CE-compliant, protection class IP00, installation up to IP21
