ETE SV1000P4S6 Single Voltage Control Transformer 1000VA 0/240V to 0/24V

Why Choose the ETE SV1000P4S6 1000 VA Single-Voltage Control Transformer?

The ETE SV1000P4S6 is a high-capacity 1000 VA (1 kVA) single-phase control circuit transformer designed to convert a 240 V AC primary supply into a 24 V AC secondary output. Manufactured by Eastern Transformers & Equipment (ETE), it forms part of the established SV single-voltage transformer range, providing reliable voltage transformation for industrial control panels, machinery and automation equipment.

The SV1000P4S6 features 0/240 V primary terminals and 0/24 V secondary terminals, delivering a dedicated 24 V AC supply for compatible contactors, relays, solenoids, signalling devices and other industrial control components. Its continuous-rated construction incorporates IP20 touch-proof terminals, Class H varnish impregnation and a core earth connection to support dependable operation and practical installation.

With a rated capacity of 1000 VA, Class E insulation and 4% voltage regulation, the SV1000P4S6 is particularly suitable for control circuits requiring greater output capacity and controlled voltage variation. Measuring 150 × 125 × 145 mm and weighing 9.8 kg, the transformer is designed for integration into industrial electrical cabinets, with the specified compatible enclosure reference EPN 3.

Reliable 24 V AC Power for Higher-Capacity Control Circuits

The ETE SV1000P4S6 provides a practical method of supplying industrial control equipment requiring 24 V AC from an available 240 V AC source. Its single-voltage design simplifies transformer selection where the primary and secondary voltages are already established, while the dedicated secondary winding provides a separate control circuit supply.

The 1000 VA rated capacity corresponds to a calculated nominal secondary current of approximately 41.67 A at 24 V AC. This makes the transformer suitable for installations with multiple compatible control devices, provided the combined steady-state load and any simultaneous energisation demands remain within the transformer's operating capabilities. Control equipment such as contactor coils and solenoids may require substantially greater power during initial energisation, so their inrush characteristics should be considered during transformer selection.

The specified 4% voltage regulation describes the change in secondary voltage between no-load and rated-load conditions at the specified primary supply. This relatively low regulation figure supports applications where stable control voltage is important for reliable relay, contactor and signalling operation. The transformer's Class E insulation system, Class H varnish impregnation and continuous-duty construction are designed to support dependable industrial service.

For panel builders, the SV1000P4S6 combines a straightforward terminal arrangement with IP20 touch-proof connections and a protective core earth terminal. The specified EPN 3 enclosure reference provides a compatible enclosure option where additional mechanical or environmental protection is required. Installations should incorporate appropriate primary and secondary circuit protection, suitable conductor sizing, protective earthing and adequate ventilation.

As a conventional AC transformer, the SV1000P4S6 supplies 24 V AC rather than 24 V DC. It should therefore be selected for equipment designed to operate from an AC control supply. Devices requiring regulated DC power will need suitable additional conversion equipment.
