Figure 8: Impedo Duo power supply Connection
The supply current is power factor corrected and the maximum supply power to the
Impedo Duo is actively limited to 30 VA enabling Impedo Duo to be powered directly
from 110V 50/60Hz VT circuits.
An internal electronic fuse protects the Impedo DUO from over- and under-voltage
conditions. The Impedo DUO will automatically disconnect from mains if excessive
current is drawn from the universal AC/DC supply input port. When this protection
was activated, it needs a few minutes to cool, during which the Impedo DUO will not
restart even with valid mains voltage.
