Mains chokes
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).
Selection table
The mains chokes are protected to IP20. Refer to page 105 for dimensions, wire
sizes and tightening torques.
