It also presents a well defined high frequency AC line impedance to the input of the HAM. To meet the listed specifications, Vicor’s P/N 30205 line filter/transient suppressor or equivalent must be used, see Figure 10. The addition of a MOV external to this filter is required to meet normal mode transient surge requirements. For applications using HAMD + BAMD or where the user desires to construct a custom HAM filter, the filter should be designed following Figure 10, the schematic of Vicor’s P/N 30205 filter. The current carrying capability of the inductors must be scaled proportionally to the number of HAM modules used. Inductance values must be selected according to Table 1. These limits are to ensure proper operation of the HAM and do not guarantee a system will meet conducted emissions specifications. For applications requiring magnetic field shielding, do not place a ferrous EMI shield over the plastic cover of the HAM module. This can cause thermal problems due to induction heating effects.
