Power Supply Module; Ferrite Core - Mitsubishi Electric MELSEC-Q Series User Manual

3.1.4

Power supply module

The precautions required for each power supply module are described
below. Always observe the items noted as precautions.
Model
A1S61PN, A1S62PN
*1
A1S63P
A1SJHCPU(S8)
*1 Filter attachment to the power cable is not required for the A1S63P product with the version
(F) and later. However, use the 24VDC panel power equipment that conforms to the CE.
*2 Make sure to attach two ferrite cores to the power line.
Attach them as close to the power supply module as possible.
Use a ferrite core whose damping characteristic is equivalent to that of the RFC-H13
produced by KITAGAWA INDUSTREIS CO., LTD.
3.1.5

Ferrite core

Use of ferrite cores is effective in reducing the conduction noise in the
band of about 10 MHz and radiated noise in 30 to 100 MHz band.
It is recommended to attach ferrite cores when the shield of the shielded
cable coming out of control panel does not work effectively, or when
emission of the conduction noise from the power line has to be
suppressed.
We tested using ferrite cores from TDK Corporation, ZCAT3035-1330
and ZCAT2032-0930, and RFC-H13 from KITAGAWA INDUSTREIS
CO., LTD.
Make sure to attach a ferrite core to a cable at the position closest to the
outlet of control panel as possible. If attached at an improper position,
the ferrite core will not work effectively.
• Ferrite core
Make sure to short the LG and FG terminals with a cable of 6 to 7cm
and ground the cable.
Use the 24VDC panel power equipment conforming to the EU
Directive.
Make sure to short and ground the LG and FG terminals.
