ETE DV300P6S4 Dual Input Voltage Control Transformer 300VA 0/240/415V to 0/110V

Why Choose the ETE DV300P6S4 300 VA Dual Input Voltage Control Transformer?

The ETE DV300P6S4 is a reliable 300 VA single-phase dual-input-voltage control transformer designed to provide a dedicated 110 V AC secondary supply from either a 240 V AC or 415 V AC primary input. Manufactured by Eastern Transformers and Equipment (ETE), this transformer belongs to the ETE DV Dual Voltage Series, developed for industrial control panels, electrical machinery, power distribution equipment and automation applications.

Unlike conventional single-input control transformers, the DV300P6S4 incorporates 0/240/415 V primary terminals, allowing the appropriate primary connection to be selected according to the available supply voltage. Its dedicated 0/110 V secondary terminals provide a nominal 110 V AC output, making the transformer suitable for industrial control circuits, contactor coils, relays and other compatible electrical equipment.

Designed for continuous-duty operation, the DV300P6S4 features Class E insulation, 8% voltage regulation, IP20 touch-proof terminals, Class H varnish impregnation and a protective core earth connection. With dimensions of 120 × 100 × 120 mm and a weight of 4.7 kg, it offers a practical solution for industrial electrical installations. The specified compatible enclosure references are EPH 3 or EPN 2.

Flexible 240 V or 415 V Input with a Dedicated 110 V Output

The principal advantage of the ETE DV300P6S4 is its dual-input-voltage primary winding arrangement. Its 0/240/415 V terminal configuration allows the transformer to be connected to either a 240 V AC or 415 V AC supply, depending on the installation requirements. This flexibility simplifies transformer selection for electrical panel builders, machinery manufacturers and maintenance engineers working with different industrial supply voltages.

When connected using the correctly selected primary terminals, the transformer is designed to provide a nominal 110 V AC secondary output. Its 300 VA capacity corresponds to a calculated rated secondary current of approximately 2.73 A. This makes it suitable for appropriately rated control devices, switching equipment and signalling circuits, provided the connected load remains within the transformer's capacity.

The specified 8% voltage regulation should be considered when selecting voltage-sensitive equipment, particularly where secondary loading varies. The dual-input arrangement also provides flexibility for standardising control panel designs across installations with different primary supply voltages. The DV300P6S4 is therefore a practical solution where a 240/415 V to 110 V AC control transformer is required.

Durable Construction for Industrial Electrical Installations

The DV300P6S4 measures 120 mm in length, 100 mm in width and 120 mm in height, with a weight of 4.7 kg. Its compact construction makes it suitable for mounting within industrial control panels, machinery electrical cabinets and suitably sized distribution enclosures.

The transformer incorporates IP20 touch-proof terminals, Class H varnish impregnation and a protective core earth connection. Its Class E insulation and design to EN 61558-1 support dependable operation in industrial control circuit applications. The specified ambient operating temperature range is −10 to +35 °C.

For applications requiring a separate enclosure, the manufacturer's specified references are EPH 3 and EPN 2. Suitable mounting, ventilation, conductor sizing and protective devices should be selected according to the requirements of the complete electrical installation. The transformer's primary terminals must be connected to the correct supply voltage, and the secondary circuit must be protected appropriately.
