3 PHASE AUTOTRANSFORMER
Coolant bores | natural convection Horizontal mounting version
TYPICAL APPLICATIONS
3 phase autotransformer according to IEC/ EN61558-2-13 for general applications without the need of a galvanic isolation, e.g. for transforming typical mains voltage to other voltages needed by tools, machinery or other devices. Autotransformers do not provide any electrical protection due to the lack of galvanic isolation between input and output windings.

3 phase autotransformer according to EN61558-2-13 Voltage range for input / output: 100 … 550 V Power range: 2 kVA ... 5 kVA
EN61558-2-13
SPECIFICATIONS
3 phase transformer, protection class I ready. Autotransformers are provided for a voltage range from 100V up to 550V (special voltage versions on request). Standard switching matrix: Yan0 (typical star load approx. 10%). If typical star load should reach rated current, switching matrix Zan0 is used. Please add switching matrix requested when ordering the transformer. For further information, don´t hesitate to contact us. Final operation position must allow natural convection through coolant bores. Due to innovative vacuum impregnation in polyester varnish, the noise level is extraordinary low. Screw terminals are contact proof according to VBG4. Transformer provides 2 loops for safe transportation or craning (core sizes > 3UI150 / 65 – 4.5kVA).

USE OF 1 PHASE AND 3 PHASE AUTOTRANSFORMERS
INFO
Mains supplied power without transformer „serial winding“
Autotransformers do not provide galvanic isolation. Electroconductive connection between input and output winding. If difference between input voltage and output voltage is small...: ...mains power may be higher ...transformed power is lower ...size can be reduced (core, copper winding)
Input
Transformed power „parallel winding“
Output Load
Please note: Equation: Regarding input/ output „upper“ or „lower voltage“ is independant, voltage related only For of 3 phase autotransformers value phase voltage is important.
Equation to calculate the requested size: Example: 1 phase autotransformer Input voltage 440V | Output voltage 400V „Rated power“ needed for application: 5kVA
lower voltage
Example shows 90% power saving compared isolating transformers. Identical equation works with 3 phase transformers. Standard circuit design autotransformers is Yan0. of 3 phase

Max. load at neutral wire is approx. max. 10% of nominal current (phase current). If 100% neutral wire load is requested, circuit design Zan0 is manufactured (Note: Yan0 design can be used in certain circumstances, if neutral wire at input provides full load and transformer star point is permanently connected to load.
