Control circuit transformers such as the ETE SV400P5S4 are used to convert an available AC supply voltage into a lower voltage suitable for electrical control equipment. This model converts a nominal 415 V AC primary supply into a 110 V AC secondary supply, providing a dedicated source of power for compatible control circuits, switching devices and industrial automation components.
The 400 VA capacity provides a calculated nominal secondary current of approximately 3.64 A at 110 V, allowing the transformer to supply appropriately rated control loads. Typical equipment includes contactor coils, control relays, signalling devices, industrial switching equipment and other 110 V AC components. Its single-voltage configuration simplifies installation where fixed primary and secondary voltages are required.
The SV series is designed for dependable continuous operation in industrial environments. The combination of touch-proof terminals, varnish-impregnated windings, Class E insulation and a protective core earth connection supports reliable control power distribution. The SV400P5S4 is therefore well suited to electrical panel builders, industrial maintenance engineers and OEM machine manufacturers requiring a dedicated 415 V to 110 V AC control transformer.
