UEC power supply
With a power supply of 400 V, the inverter voltage U
Z
is 565 Vdc, and with a power supply of 480 V
it is 678 Vdc.
EN 61800-5-1 requires a non-detachable connection to the line power supply.
If the power supply is other than 400 V, an autotransformer is required. It must comply at least
with the connection specifications of the UEC 11x.
Connecting terminals UEC 111, UEC 112
