DC DRIVE FILTER MOUNTING KITS
: EMC FILTERS AND CHOKES
Ext Filter = Filter fitted externally to the drive
Ext FP Filter = Filter fitted externally behind the drive
with identical Foot Print and mounting centres to drive.
Description
- A range of custom designed optional EMC (ElectroMagnetic Compatibility) filters and line chokes are available for use with the SSD Parvex product range. These have been designed to provide cost effective and easily implemented solutions for a variety of standard installations as well as less common requirements such as unusually long cable runs, 500V ac applications and non-earth referenced supplies.
EMC filters
- EMC filters have been designed to facilitate compliance with EMC Standard BS EN 61800- 3:1997 (Incorporating Amendment
No.1) - "Adjustable speed electrical power drive systems - Part 3". When installed in accordance with the relevant manual most products comply without the need for any external EMC filters. The table below summarises compliance to the standard for each product.
Environnement 1 : relates to drives connected to electrical supplies shared with domestic dwellings
Environnement 2 : relates to drives connected to electrical supplies not shared with domestic dwellings
TN Supply = Earth Referenced AC Supply up to 460V ac
IT Supply = Non-Earth Referenced AC Supply up to 500V ac
Ext Filter = Filter fitted externally to the drive
Ext FP Filter = Filter fitted externally behind the drive with identical Foot Print and mounting centres to drive.
Chokes
- The NRT and NRTP chokes are recommended as line chokes for the three-phased 590P et 590P-DRV DC drives. They help to
lower the power supply's harmonic content and disturbances. The NRTP chokes are fitted with semiconductor fuses.
