Why Choose the ETE DV150P6S5 150 VA Dual-Input-Voltage Control Transformer?
The ETE DV150P6S5 is a versatile 150 VA single-phase industrial control transformer designed to provide a 240 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 series, developed for electrical control panels, industrial machinery and automation systems requiring flexible primary voltage connections.
Unlike a conventional single-input-voltage transformer, the DV150P6S5 features 0/240/415 V primary terminals, allowing the installer to select the appropriate input connection for the available supply. Its 0/240 V secondary terminals provide a nominal 240 V AC output for compatible control relays, contactor coils, signalling devices and other industrial control equipment. The dual-input arrangement is particularly useful for machinery manufacturers and panel builders producing equipment for installations with different supply voltages.
With a rated apparent power of 150 VA, Class E insulation and 10% voltage regulation, the DV150P6S5 combines practical electrical performance with robust industrial construction. Its dimensions of 96 × 87 × 103 mm and weight of 2.8 kg make it suitable for installation within compact control cabinets. The transformer is compatible with ETE EPH 2 or EPN 1 enclosures and supports a DIN rail mounting option.

Reliable 240 V AC Control Power with Dual Primary Voltage Flexibility
The ETE DV150P6S5 offers a practical solution for industrial applications where a consistent 240 V AC control voltage is required but the available primary supply may be either 240 V AC or 415 V AC. Its tapped primary winding enables the appropriate supply voltage to be selected during installation, reducing the need to specify separate transformer models for different electrical supply arrangements.
When connected to a 240 V AC supply, the transformer uses the designated 0/240 V primary terminals. For a 415 V AC supply, the designated 0/415 V primary terminals are used. In both configurations, the nominal secondary output remains 240 V AC. The primary voltage connections are alternatives and must not be energised simultaneously from separate supplies.
The 150 VA continuous apparent power rating corresponds to a calculated nominal full-load secondary current of 0.625 A at 240 V AC. This makes the transformer suitable for appropriately sized industrial control circuits, including compatible relay coils, contactors and signalling devices. Where electromagnetic components have significant starting or energisation currents, their inrush VA requirements should be considered in addition to their normal operating consumption.
The specified 10% voltage regulation describes the change in secondary voltage between no-load and rated-load conditions. This characteristic should be considered when selecting voltage-sensitive control equipment, particularly where the connected load varies significantly during machine operation.
The DV150P6S5 incorporates Class E insulation, Class H varnish impregnation, IP20 touch-proof terminals and a protective core earth connection. Its compact dimensions and available DIN rail mounting option make it practical for control cabinet installation, while the EPH 2 or EPN 1 enclosure references provide compatible protective enclosure options.
Correct primary and secondary circuit protection, protective earthing, conductor sizing and ventilation should be incorporated into the installation. Although the transformer can accept a 415 V supply between suitable conductors of a three-phase system, it remains a single-phase transformer and does not provide three-phase output. Its secondary supplies 240 V AC, not a regulated DC voltage.
