" <strong>EMI</strong>GUARDr eliminates both surge noises and <strong>EMI</strong><br />
noises due to its dielectric varistor material.<br />
" Effective when high frequency noise and high voltage<br />
surge suppression are required, and also in situations<br />
when surging starts at extremely high speeds. This type<br />
of surging cannot be eliminated with general type<br />
varistors.<br />
