Notes	Ordering example: Transformer STZ…(400 V/200 V) with 1000 VA and a secondary additional winding for 100 V and 200 VA. It results in a necessary rating of 1200 VA. The part no. selected is: STZ1,3(400/200) For pricing of the additional winding, the current is calculated as follows: I = S/U I = Current S = Apparent power of the additional winding U = Voltage of the additional winding I = 200/100 = 2 A ￫ +ZW16 For the secondary additional winding, the correct suffix is: +ZW16S(100V200VA)
