Connection to PC is carried out via a standard host/device
USB cable. The USB connection is galvanically isolated from
the supply voltage (PELV) and other high-voltage
terminals. The USB connection is not galvanically isolated
from protection earth. Use only isolated laptop/PC as
connection to the USB connector on the unit or an
isolated USB cable/converter.
Protection and Features:
•
Temperature monitoring of the heatsink ensures that the active filter trips if the temperature reaches a predefined
level. An overload temperature cannot be reset until the temperature of the heatsink is below the values stated in
the tables on the following pages.
•
If a mains phase is missing, the Active filter trips.
•
The active filter has a short circuit protection current rate of 100kA if properly fused
•
Monitoring of the intermediate circuit voltage ensures that the filter trips if the intermediate circuit voltage is too
low or too high.
•
The Active filter monitors the mains current as well as internal currents to reassure that current levels do not reach
critical levels. In case current exceed a critical level the filter trips.
