Why Choose the ETE XMS50P5S6 Class II Enclosed Safety/Isolating Transformer?
The ETE XMS50P5S6 is a compact 50 VA single-phase Class II enclosed safety/isolating transformer designed to provide a dedicated 24 V AC output from a nominal 415 V AC primary supply. Part of the ETE XMS stock control transformer range, it combines an integral moulded housing, Class II construction and flexible mounting options in a practical solution for industrial electrical control panels, machinery and auxiliary AC circuits.
Featuring primary terminals marked 0/415V and secondary terminals marked 0/24V, the XMS50P5S6 provides straightforward voltage transformation for compatible 24 V AC equipment. Its Class II construction is a defining feature of the XMS range, providing a double-insulated or reinforced-insulated protection concept rather than relying on protective earthing of accessible conductive parts. The transformer is supplied in an integral moulded housing and is suitable for DIN rail or chassis mounting, offering flexibility during electrical panel design and installation.
With a rated apparent power of 50 VA, Class F insulation and compact dimensions of 90 × 106 × 87 mm, the ETE XMS50P5S6 is well suited to applications requiring a dedicated low-voltage AC supply without the bulk of a larger control transformer. Weighing 1.3 kg, it provides a practical enclosed transformer option for panel builders, electrical contractors, OEM machinery manufacturers and industrial maintenance engineers.

The ETE XMS50P5S6 is designed for applications requiring a 24 V AC supply derived from a nominal 415 V AC input. Its primary terminals are marked 0/415V, while the secondary terminals are marked 0/24V. This straightforward input and output arrangement makes it suitable for equipment designed to operate from a dedicated 24 V AC transformer supply, provided the electrical load remains within the specified 50 VA rating.
A key feature of the XMS50P5S6 is its Class II construction. Class II electrical equipment uses double or reinforced insulation as its protective measure, rather than depending on protective earthing of accessible conductive parts. This construction should not be confused with the transformer's separate Class F insulation specification, which describes the thermal classification of its insulation system. Both classifications are relevant to product selection, but they address different aspects of electrical design.
The transformer also features an integral moulded housing and supports DIN rail or chassis mounting. DIN rail mounting can simplify integration into suitably arranged electrical cabinets, while chassis mounting offers an alternative for machinery and equipment with dedicated mounting positions. The enclosure reference describes the supplied housing; it does not, by itself, establish an ingress protection rating or suitability for exposed outdoor environments.
Its 50 VA total rated apparent power must be considered when selecting connected equipment. At a nominal 24 V output, 50 VA corresponds to approximately 2.08 A of apparent-power-based output current under rated conditions. This calculated value is a sizing reference rather than a separately specified manufacturer current rating. Connected equipment must remain within the transformer's permitted operating limits, including any relevant starting or inrush requirements.
Installation should be undertaken by suitably qualified personnel in accordance with the manufacturer's instructions and applicable electrical requirements. Appropriate primary and secondary circuit protection, conductor selection, ventilation, clearances and mechanical support must be provided. The Class II construction should be maintained as intended, without modifications that could compromise the transformer's insulation or protective design.
