Why Choose the ETE DV50P6S4 50 VA Dual Input Voltage Control Transformer?
The ETE DV50P6S4 is a compact and reliable 50 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, machinery, electrical distribution equipment and automation applications.
Unlike a conventional single-input control transformer, the DV50P6S4 features 0/240/415 V primary terminals, allowing the installer to select the appropriate primary connection for the available supply. Its dedicated 0/110 V secondary terminals provide a nominal 110 V AC output, making it particularly useful for industrial control circuits, contactor coils, relays and other compatible electrical equipment.
Designed for continuous-duty operation, the DV50P6S4 incorporates Class E insulation, 15% voltage regulation, IP20 touch-proof terminals, Class H varnish impregnation and a core earth connection. With dimensions of just 75 × 71 × 88 mm and a weight of 1.2 kg, it offers a practical solution for space-conscious electrical installations. The specified compatible enclosure references are EPH 1 or EPN 1.

Flexible 240 V or 415 V Input with a Dedicated 110 V Output
The principal advantage of the ETE DV50P6S4 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 can simplify transformer selection for electrical panel builders, machinery manufacturers and maintenance engineers working with different industrial supply voltages.
Regardless of which correctly selected primary connection is used, the transformer is designed to provide a nominal 110 V AC secondary output. Its 50 VA capacity corresponds to a calculated rated secondary current of approximately 0.45 A. The connected control circuit must be sized to remain within the transformer's rating, with appropriate consideration given to the inrush characteristics of contactors and other inductive loads.
The specified 15% voltage regulation should also be considered when selecting voltage-sensitive equipment, particularly where secondary loading varies. The combination of a dual-input arrangement, compact dimensions and industrial transformer construction makes the DV50P6S4 a practical solution for installations requiring a flexible 240/415 V to 110 V AC control transformer.
Compact Construction for Industrial Control Panels
Measuring 75 mm in length, 71 mm in width and 88 mm in height, the DV50P6S4 is designed for installation in control cabinets and machinery electrical compartments where available mounting space may be limited. Its 1.2 kg weight makes it manageable during assembly, replacement and routine electrical maintenance.
The transformer incorporates IP20 touch-proof terminals, Class H varnish impregnation and a protective core earth connection. It is designed to EN 61558-1 with Class E insulation and is suitable for continuous-rated control circuit applications within the manufacturer's stated operating conditions.
For installations requiring an additional enclosure, the manufacturer's specified enclosure references are EPH 1 and EPN 1. Suitable mounting arrangements, ventilation, wiring protection and protective devices should be selected in accordance with the requirements of the complete electrical installation.
