As a result of the broad input voltage range, the TVD 1.3 can be attached to most internationally used power
systems without the use of a transformer. With mains rated voltages of < 380 V or > 480 V a transformer is
required. The following transformers can be used in conjunction with the TVD 1.3 for rated mains voltage as listed
in column 2 of the table. A special transformer type or transformer connection for each mains voltage is not
required.
The connected load for the TVD 1.3 is dependent upon the voltage. When calculating the connected load take
the output voltage of the mains transformer into account.
Example: mains voltage or transformer inputv oltage = U

= 525 V, ratio = ü = 1.26
