Required External EMI Filters for
DIN-A-MITE with More than 6 A Loads
An external EMI filter must be used in conjunction with the DIN-
A-MITE for loads in excess of six amperes (6A) at 150 to 250 kHz.
Without a filter applied, the DIN-A-MITE does not comply with
the conducted emissions standard for loads above 6A at 150 to 250
KHz.
Watlow has verified that two types of filters will suppress
electromagnetic interference (EMI) created by the DIN-A-MITE
power controller to within the CE requirements.
A tank filter supplied by Crydom or Watlow, installed across the
power lines, suppresses EMI on the power lines. See figure below.
See Table 1 for the correct filter.

WARNING:
The tank filters specified may suppress desirable communications carried
on power lines in the 150 to 250 kHz region. The filters may suppress
carrier current such as that used for infant monitors and medical alert
systems. Verify that suppressed carrier current or other desirable
communications on power lines creates no hazard to people or property.
Failure to observe this warning could result in damage to property, and
injury or death for personnel.
Ó
WARNING:
All filter installation and wiring must be performed by qualified personnel,
and conform to local and national electrical codes. Failure to observe this
warning could result in damage to property, and injury or death for
personnel.
