12 & 18 Pulse Converter Kits
12 / 18 Pulse Converter Filters (Type PCK and Type HMP12) 480 volts 60Hz
Capacitor free harmonic filter solutions. Upgrade most 6-Pulse drives with our exclusive 12 or 18 Pulse Converter Upgrade Kit, or supply your 12-pulse drive with our economical Hybrid 12-pulse filter.
APPLICATION: Multi-pulse (12 & 18 pulse) filter solutions are typically demanded for applications that involve a very high percentage of motor drive loads as compared with the total facility load. This is especially useful in the HVAC/R, municipal water and wastewater industries where lower harmonic distortion is demanded. The following chart demonstrates the typical harmonic current distortion associated with 6, 12 and 18 pulse drives.

Converter Upgrade Kits (Type PCK)
Arteche offers a convenient kit that upgrades a typical 6-pulse drive to either 12 or 18 pulse, provided that a series connection may be made in the drive's dc bus.
Filter for 12-pulse drives
12-pulse phase shifted power source (Type HMP12)
For drives that are already configured as 12-pulse, Arteche offers a convenient and economical means of providing the phase shifted 6 winding power source. This filter includes a phase shifting transformer to supply one bridge rectifier plus a reactor to supply the other bridge rectifier.
