ETE SV1000P4S4 Single Voltage Control Transformer 1000VA 0/240V to 0/110V

Why Choose the ETE SV1000P4S4 1000 VA Control Transformer?

The ETE SV1000P4S4 is a robust, industrial-grade 1000 VA (1 kVA) single-phase control transformer designed to convert a 240 V AC primary supply into a 110 V AC secondary output. Manufactured by Eastern Transformers & Equipment (ETE), this transformer forms part of the established ETE SV single-voltage stock control transformer range, developed for electrical panel builders, machinery manufacturers, OEMs and industrial automation applications requiring a dependable control circuit power supply.

Designed for continuous-duty operation, the SV1000P4S4 combines a substantial 1 kVA apparent power rating with a durable industrial construction. Its Class E insulation system, Class H varnish impregnation, IP20 touch-proof terminals and dedicated core earth connection support reliable integration into appropriately designed electrical control panels and industrial equipment.

Featuring 0/240 V primary terminals and 0/110 V secondary terminals, the ETE SV1000P4S4 provides a nominal 110 V AC output for compatible control circuits and auxiliary equipment. Its specified 4% voltage regulation makes it particularly suitable for applications where secondary voltage variation under changing load conditions is an important design consideration.

With dimensions of 150 × 125 × 145 mm, a weight of 9.8 kg and a specified EPN 3 enclosure reference, the SV1000P4S4 offers a practical solution for industrial machinery, electrical control cabinets and transformer installations requiring a 240 V to 110 V AC supply.

Reliable 110 V AC Control Power for Industrial Machinery

Industrial control transformers provide a dedicated AC electrical supply for machinery control circuits, switching devices and auxiliary equipment. The ETE SV1000P4S4 converts a nominal 240 V AC primary input into a 110 V AC secondary output through electromagnetic induction, allowing compatible industrial devices to operate from a transformer-fed control circuit.

The transformer's 1000 VA continuous rating makes it suitable for control systems with greater combined load requirements than lower-rated SV models. Based on the nominal secondary voltage, its calculated full-load secondary current is approximately 9.09 A. This figure is derived from the rated apparent power divided by the nominal secondary voltage and should be used alongside the transformer's operating limits, circuit protection requirements and connected load characteristics.

A key feature of the SV1000P4S4 is its specified 4% voltage regulation. Transformer voltage regulation describes the change in secondary voltage between no-load and rated-load conditions under the relevant test conditions. This characteristic is important when selecting a transformer for contactors, relays and other electrical control equipment that must operate within defined voltage tolerances.

The Class E insulation system, Class H varnish impregnation and IP20 touch-proof terminals contribute to the transformer's industrial construction. Its dedicated core earth connection provides for protective earthing as part of a correctly designed electrical installation.

The SV1000P4S4 is associated with the EPN 3 enclosure reference for installations requiring additional protection. Appropriate primary and secondary overcurrent protection, earthing, ventilation, cable sizing and installation clearances must be considered when integrating the transformer into an electrical panel or machinery assembly.
