The ETE DV250P6S6 is designed for industrial electrical systems where the available primary supply may be either 240 V AC or 415 V AC. Its tapped primary winding features 0/240/415 V terminals, allowing the correct input connection to be selected during installation. When connected to the matching primary voltage, the transformer provides a nominal 24 V AC secondary output through its 0/24 V secondary terminals.
This dual-input configuration is particularly useful for OEM machinery manufacturers and electrical panel builders producing equipment for different industrial electrical supplies. The DV250P6S6 can accommodate either supported primary voltage without requiring a separate transformer model for each supply arrangement. The primary terminals must always be connected according to the available voltage and the manufacturer's wiring instructions; the two input voltage options are alternatives, not separate supplies to be connected simultaneously.
The transformer's 250 VA rating provides a calculated full-load secondary current of approximately 10.42 A at its nominal 24 V AC output. This figure is derived by dividing the rated apparent power by the secondary voltage. When selecting a transformer, engineers should consider the total apparent power of connected equipment, permissible voltage variation, operating conditions and any short-duration inrush current requirements, particularly when supplying electromagnetic contactors or multiple control devices.
The specified 8% voltage regulation describes the change in secondary voltage between no-load and rated-load conditions under the applicable test conditions. This characteristic should be considered when supplying control equipment with defined operating voltage tolerances. Although the transformer provides a nominal 24 V AC output, the actual secondary voltage can vary with supply voltage and connected load.
The DV250P6S6 incorporates Class E insulation, IP20 touch-proof terminals, Class H varnish impregnation and a dedicated core earth connection. For installations requiring additional physical protection, the specified enclosure references are EPH 3 or EPN 2. Correct primary and secondary circuit protection, protective earthing, ventilation, conductor sizing and suitable mounting arrangements remain essential for safe and dependable operation.
