SCHURTER: 3-Phase EMC Filter Series Designed for Machine Safety
September 22, 2022
SCHURTER expands the FMAC NEO and FMAD NEO 3-phase filter families to meet IEC 60204-1. Downsized for smaller footprint, without any compromise to performance, the two new filter series are suitable for use in energy applications such as EV fast charging and battery storage, as well as industrial applications in general. Any machine or system introduced to the European market must bear a CE marking. This marking signifies that the manufacturer guarantees the product is safe for humans and machine equipment and complies with all applicable legal and technical requirements. T
he Machinery Directive 2006/42/EC and the Low Voltage Directive 2014/35/EU define minimum standards concerning safety and occupational health requirements in Europe. The details for implementation are defined in separate specifications, known as harmonizing standards. One of these harmonizing standards is IEC 60204-1, which defines requirements for electrical safety for machines, and applies to electrical, electronic, and programmable electronic equipment as well as networked machines, including control cabinets.
The FMAC NEO and FMAD NEO filters meet all machine safety requirements outlined in IEC 60204-1 standard, specifically that the filters have a short discharge time of the capacitors so that they have a touchable residual voltage of less than 60 V in 1 or 2 seconds after disconnecting the voltage. The insulation value between phases and ground is at least 1 MΩ, achieved with larger resisters. Additionally, any AC socket on the machine is RCD protected 30 mA for human protection.
Designed for 3-phase, or 3-phase with neutral, applications, the FMAC NEO and FMAD NEO series are ENEC and UL approved for rated currents 16 to 230 A at 300/520 VAC 50/60 Hz at an ambient temperature of 50°C. Standard versions are designed for industrial applications with leakage currents of <13 mA. Versions <3 mA are offered for leakage-critical applications. The dielectric strength is >2.25 kVDC L-L and 2.75 kVDC L-PE. Operating temperature range is from -40 to 100 C°.
Pricing for FMAC NEO and FMAD NEO starts at $80 each at 50-piece quantities.
