Why Choose the ETE DV150P6S4 150 VA Dual-Input Control Transformer?
The ETE DV150P6S4 is a versatile 150 VA single-phase industrial control transformer designed to provide a nominal 110 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 and industrial automation applications requiring flexible primary voltage connections.
Unlike a single-input-voltage transformer, the DV150P6S4 features a 0/240/415 V primary terminal arrangement, allowing installers to select the appropriate primary connection for the available supply. Its 0/110 V secondary terminals provide a single nominal 110 V AC output, making it suitable for machinery and electrical control systems designed around a 110 V AC control supply.
The DV150P6S4 combines a 150 VA apparent power rating with Class E insulation, 10% voltage regulation and industrial construction. Its dimensions of 96 × 87 × 103 mm and specified weight of 2.8 kg make it a practical option for electrical control panels where installation space must be considered.
With specified EPH 2 or EPN 1 enclosure references, the ETE DV150P6S4 offers flexibility for both panel-mounted and appropriately enclosed installations. Its dual-input arrangement is particularly useful for OEMs and panel builders working with equipment intended for different industrial supply voltages.

The ETE DV150P6S4 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 provides 0/240/415 V terminals, enabling the correct primary connection to be selected during installation. When connected to the appropriate input voltage, the transformer provides a nominal 110 V AC secondary output through its 0/110 V secondary terminals.
This dual-input configuration is useful for machinery manufacturers, OEMs and electrical panel builders producing equipment for different supply arrangements. A single DV150P6S4 model can accommodate either supported primary voltage, reducing the need to specify separate transformer variants for 240 V AC and 415 V AC installations. The primary terminals must always be connected according to the actual supply voltage and the manufacturer's wiring instructions.
With a 150 VA rating, the transformer provides a calculated full-load secondary current of approximately 1.36 A at its nominal 110 V AC output. This figure is calculated by dividing the rated apparent power by the secondary voltage. Transformer sizing should also consider the total connected load, power factor, switching characteristics and short-duration inrush requirements, particularly when supplying contactors or other electromagnetic devices.
The specified 10% voltage regulation is an important consideration when evaluating secondary voltage variation under different load conditions. Connected equipment must be capable of operating within the actual secondary voltage range expected in service, rather than assuming the output will remain exactly 110 V AC under all conditions.
The DV150P6S4 features a Class E insulation system, IP20 touch-proof terminals, Class H varnish impregnation and a dedicated core earth connection. For installations requiring additional protection, the specified enclosure references are EPH 2 or EPN 1. Correct primary and secondary overcurrent protection, protective earthing, ventilation and mounting arrangements remain essential for safe operation.
