ETE XMS100P5S4 Class II Enclosed Safety Transformer 100VA 0/415V to 0/110V

Why Choose the ETE XMS100P5S4 100 VA Class II Enclosed Safety/Isolating Transformer?

The ETE XMS100P5S4 is a compact 100 VA single-phase Class II enclosed safety/isolating transformer designed for industrial electrical control panels, machinery, automation equipment and AC control circuits. Part of the ETE XMS enclosed transformer range, it converts a nominal 415 V AC primary supply into a 110 V AC secondary output, providing a practical solution for industrial equipment requiring a lower control voltage.

The XMS100P5S4 features a 0/415 V primary terminal arrangement and a 0/110 V secondary terminal arrangement. Its Class II protective construction and integral moulded housing provide an enclosed transformer design suitable for integration into compatible electrical assemblies. The transformer supports DIN rail or chassis mounting, offering installation flexibility for different control panel layouts and equipment configurations.

With a rated apparent power of 100 VA and Class F insulation, the ETE XMS100P5S4 is suitable for appropriately rated 110 V AC control loads. Its dimensions of 90 × 106 × 96 mm and weight of 2.2 kg make it a convenient choice for electrical cabinets where efficient use of installation space is important. The specified enclosure is an integral moulded housing.

415 V AC Input with 110 V AC Safety/Isolating Output

The ETE XMS100P5S4 is designed to convert a nominal 415 V AC input into a 110 V AC output for compatible industrial control and signalling equipment. Its primary winding uses 0/415 V terminals, while its secondary winding uses 0/110 V terminals, providing a straightforward fixed-voltage transformer configuration.

Unlike multi-tap transformers with selectable secondary voltages, the XMS100P5S4 is specified with a single 110 V AC output connection. This makes it suitable for installations where the required control voltage is known and a compact, enclosed transformer is preferred. Its 100 VA capacity supports appropriately rated control loads without requiring a larger transformer than the application demands.

Based on its 100 VA rating, the theoretical full-load secondary current is approximately 0.91 A at 110 V AC. This is calculated by dividing the rated apparent power by the nominal secondary voltage. Actual permissible loading, protective device selection and operating conditions must follow ETE's specifications and the requirements of the connected equipment.

The transformer's Class II construction provides a protective insulation arrangement, while its Class F insulation defines the winding insulation thermal classification. These are separate characteristics and should not be confused. The integral moulded housing and DIN rail or chassis mounting options support installation into suitable electrical assemblies. Correct primary and secondary connections, circuit protection, ventilation and mounting arrangements remain essential for safe operation, particularly when working with a 415 V AC primary supply.
