FAQ
FAQ
Q1. What is the 1321-M048 used for?
It is a common mode choke used in VFD systems to reduce electrical noise and protect motor insulation.
Q2. Where is it installed?
It is installed between the drive output terminals and the motor cable.
Q3. What problem does it solve?
It reduces EMI (electromagnetic interference), dv/dt spikes, and common-mode voltage stress on motor cables.
Q4. Is it an active or passive device?
It is a passive inductive component (no electronics or control logic).
Q5. What drives is it compatible with?
It is commonly used with Allen-Bradley PowerFlex drives and other 460/575 VAC VFD systems.
Q6. Does it require configuration?
No configuration is required; it works purely through electrical induction.
Q7. Is it directional?
No, it is non-directional in terms of power flow.
Q8. What is its weight?
Approximately 0.5–1.2 kg, typically around 0.54 kg (1.19 lb).
