Control circuit transformers such as the ETE SV750P4S4 provide voltage transformation between an industrial electrical supply and lower-voltage control equipment. By converting a 240 V AC input into a 110 V AC secondary supply, this transformer enables compatible contactor coils, relays, signalling devices and control components to operate from a dedicated control voltage.
The 750 VA continuous-duty rating enables the transformer to supply connected control equipment within its rated apparent power capacity. At the nominal secondary voltage of 110 V AC, the corresponding calculated full-load current is approximately 6.82 A. The specified 4% voltage regulation describes the change in secondary voltage between no-load and rated-load conditions, helping electrical designers account for voltage variation when selecting control equipment.
The ETE SV series is designed for industrial panel builders and machinery manufacturers requiring dependable control voltage transformation. Its IP20 touch-proof terminals, Class H varnish impregnation and protective core earth connection support robust installation within suitably designed electrical enclosures. The Class E insulation system and EN 61558-1 design basis further support its suitability for industrial control circuit applications.
For applications requiring additional physical protection, the SV750P4S4 can be installed using a suitable enclosure corresponding to the EPN 3 reference. Correct primary and secondary circuit protection, protective earthing, ventilation and conductor sizing should be incorporated into the installation design. The 0/110 V secondary is a single 110 V winding and should not be confused with a centre-tapped 55/0/55 V supply commonly associated with certain 110 V site transformers.
