Why Choose the ETE DV400P6S5 400 VA Dual-Input Control Transformer?
The ETE DV400P6S5 is a versatile 400 VA single-phase industrial control transformer designed to provide a nominal 240 V AC secondary output from either a 240 V AC or 415 V AC primary supply. Manufactured by Eastern Transformers & Equipment (ETE), this transformer belongs to the established ETE DV dual-input-voltage stock control transformer range, developed for electrical panel builders, machinery manufacturers, OEMs and industrial automation applications requiring flexible primary voltage connections.
Featuring a 0/240/415 V primary terminal configuration, the DV400P6S5 allows the appropriate input connection to be selected according to the available supply voltage. Its 0/240 V secondary terminals provide a single nominal 240 V AC output, making it suitable for compatible control circuits, switching equipment and auxiliary electrical loads. The dual-input design helps standardise transformer selection across machinery and control panels intended for different industrial electrical supplies.
With a rated apparent power of 400 VA, Class E insulation and 8% voltage regulation, the ETE DV400P6S5 provides a practical solution for control systems requiring a dedicated AC supply. Its continuous-duty design, IP20 touch-proof terminals, Class H varnish impregnation and core earth connection support installation in appropriately designed industrial electrical assemblies.
The transformer measures 120 × 108 × 120 mm and weighs 5.5 kg. Its specified EPH 3 or EPN 2 enclosure references make it suitable for consideration in electrical control cabinets, machinery panels and appropriately enclosed transformer installations.

The ETE DV400P6S5 is designed for industrial electrical installations where the available primary supply may be either 240 V AC or 415 V AC. Its primary winding features 0/240/415 V terminals, allowing the correct connection to be selected during installation. When supplied through the appropriate primary terminals, the transformer provides a nominal 240 V AC secondary output through its 0/240 V terminals.
This dual-input arrangement is useful for electrical panel builders and OEM machinery manufacturers producing equipment for different supply configurations. On a 415 V AC supply, the transformer performs a step-down conversion to 240 V AC. On a 240 V AC supply, it provides a nominal 240 V AC secondary output through the transformer. The two primary voltage options are alternative connections and must not be treated as independent supplies that can be connected simultaneously.
The 400 VA rating corresponds to a calculated nominal full-load secondary current of approximately 1.67 A at 240 V AC. This value is obtained by dividing the transformer's rated apparent power by its nominal secondary voltage. Engineers should consider the total connected apparent power, load power factor, permissible voltage variation and any short-duration inrush requirements when determining whether the DV400P6S5 is suitable for a particular application.
The specified 8% voltage regulation is an important consideration for control circuits with defined operating voltage tolerances. Voltage regulation relates to the change in secondary voltage between no-load and rated-load conditions under the relevant test conditions. The actual secondary voltage may therefore vary with primary supply voltage and connected load rather than remaining exactly 240 V AC at all times.
The DV400P6S5 incorporates Class E insulation, IP20 touch-proof terminals, Class H varnish impregnation and a core earth connection. For installations requiring additional protection, the specified enclosure references are EPH 3 or EPN 2. Appropriate primary and secondary overcurrent protection, conductor sizing, protective earthing, ventilation and mounting arrangements must be considered during installation.
