Reliable 110 V AC Power for Industrial Control Systems
The ETE SV1000P5S4 provides a dependable method of supplying industrial control equipment requiring 110 V AC from an available 415 V AC source. Its single-voltage primary and secondary arrangement makes it suitable for installations with established supply and control voltage requirements, providing a dedicated secondary winding for compatible electrical control equipment.
The 1000 VA continuous-duty rating corresponds to a calculated nominal secondary current of approximately 9.09 A at 110 V AC. This capacity enables the transformer to supply multiple compatible control devices, provided their combined steady-state loads and simultaneous energisation requirements remain within its operating capabilities. Contactors, solenoids and electromagnetic relays may draw significantly greater apparent power during initial energisation, making inrush performance an important consideration during transformer selection.
The specified 4% voltage regulation describes the secondary voltage change between no-load and rated-load conditions. This supports control circuit designs where voltage stability is important for dependable operation of contactors, relays and signalling devices. The Class E insulation system, Class H varnish impregnation and continuous-rated construction provide a robust basis for industrial service.
The SV1000P5S4 is equipped with IP20 touch-proof terminals and a core earth terminal for integration into appropriately designed electrical installations. The specified EPN 3 enclosure reference provides an enclosure option where additional physical protection is required. Primary and secondary circuit protection, conductor sizing, protective earthing and ventilation must be considered during installation.
Although the transformer may be connected across two suitable phases of a three-phase electrical supply where the phase-to-phase voltage is 415 V AC, the SV1000P5S4 itself is a single-phase transformer. Its 0/110 V secondary winding provides a nominal 110 V AC output and should not be confused with a centre-tapped 55/0/55 V construction used in some portable site supply systems.
