Sample order for screw-less terminal

STEZ0,5(400/230)
Determination of the current:
Iprim = SN/(Uprim x η)
Isec = SN/Usec
SN = rated transformer output
Uprim = primary voltage
Usec = secondary voltage
η = efficiency (refer to table technical data)
Iprim = 500 VA/(400 V x 0,93) = 1,34 A < 20 A
Isec = 500 VA/230 V = 2,17 A < 20 A

Number depending on the terminal points:
2 on the secondary side
4 on the primary side
Order types:
1 unit STN0,5(400/230)


Sample order:
Transformers STEZ...(400 V/200 V) with 1000 VA und with 1 additional winding on the secondary side for 100 V and 200 VA. The resulting required output is 1200 VA.

Type to be selected: STZ1,3(400/200)

To determine the price of the additional winding, the current is calculated as follows:
I = S/U
I = current
S = apparent output of the additional winding
U = voltage of the additional winding

I = 200 VA/100 V = 2 A = +ZW16

For the additional winding on the secondary side,
the correct type affix reads:
+ZW16S(100 V/200 VA)

5 additional windings on the primary and/or secondary side can be ordered. Additional windings on the primary side on request.
