Flexible 240 V or 415 V Primary Input with 110 V AC Secondary Output
The ETE DV500P6S4 dual voltage transformer offers the flexibility of two selectable primary supply voltages. Its 0/240/415 V primary terminals allow the transformer to be connected to a 240 V AC supply or a 415 V AC supply using the designated terminal connections. This makes the unit particularly useful for panel builders and machinery manufacturers supplying equipment to installations with different electrical distribution arrangements.
The transformer provides a dedicated nominal 110 V AC secondary output through its 0/110 V secondary terminals. With a rated apparent power of 500 VA, the calculated secondary current at nominal voltage is approximately 4.55 A. Engineers should consider the combined steady-state load, switching inrush and operating characteristics of connected devices when determining transformer suitability.
Its specified 8% voltage regulation is an important consideration for applications involving varying control circuit loads. The actual secondary voltage can change with loading, so voltage-sensitive equipment should be selected and assessed accordingly. The DV500P6S4 is therefore suitable for appropriately designed industrial circuits requiring a 240/415 V to 110 V AC control transformer.
Industrial Transformer Construction and Enclosure Selection
The DV500P6S4 combines a 500 VA rating with an overall size of 135 mm in length, 105 mm in width and 125 mm in height. Its 6.2 kg weight should be considered when selecting the mounting surface, fixings and supporting panel structure.
The transformer features Class E insulation, IP20 touch-proof terminals, Class H varnish impregnation and a protective core earth connection. The ETE DV series is designed for continuous-rated control circuit operation, with a specified ambient temperature range of −10 to +35 °C and construction designed to EN 61558-1.
The specified enclosure reference for this model is EPN 3. When incorporating the transformer into an electrical installation, engineers should provide suitable ventilation, electrical protection, cable management and protective earthing in accordance with the complete system design. Primary voltage selection must match the actual supply, and the connected secondary load must remain within the transformer's rating.
