What this chapter contains

This chapter describes how to select and install mains chokes for the ACSM1-04.
The chapter also contains the relevant technical data.

When is a mains choke required?

The ACSM1-04 does not necessarily require a mains choke for operation; the need
for a choke should be determined on a case-by-case basis. Mains chokes are
typically used to
• reduce harmonics in the input current
• achieve a reduction in the r.m.s. input current
• reduce supply disturbance and low-frequency interference
• increase the allowed DC bus continuous power
• ensure even current distribution in common DC configurations (see page 56).
