Control circuit transformers such as the ETE SV750P4S6 provide voltage transformation between an industrial electrical supply and lower-voltage control equipment. By converting a 240 V AC input into a 24 V AC secondary supply, this transformer enables compatible contactor coils, relays, signalling devices and control components to operate from a dedicated AC control voltage.
The 750 VA rated apparent power allows the transformer to support connected control equipment within its rated load capacity. At the nominal secondary voltage of 24 V AC, the corresponding calculated full-load secondary current is 31.25 A. The specified 4% voltage regulation describes the variation in secondary voltage between no-load and rated-load conditions, helping electrical designers account for voltage changes when selecting control equipment.
The ETE SV series is developed for industrial panel builders and machinery manufacturers requiring dependable control voltage transformation. Its IP20 touch-proof terminals, varnish-impregnated construction and protective core earth connection support practical installation within suitably designed electrical enclosures. The Class E insulation system and EN 61558-1 series design basis further support its suitability for industrial control circuit applications.
For applications requiring additional physical protection, the SV750P4S6 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. As the transformer provides a 24 V AC output, equipment requiring 24 V DC will need a suitable rectified and regulated power supply. Control circuits with high contactor inrush currents should also be assessed for their starting VA requirements rather than selected solely on steady-state load.
Typical Applications
