Why Choose the ETE DV250P6S5 250 VA Dual-Input Control Transformer?
The ETE DV250P6S5 is a versatile 250 VA single-phase industrial control transformer designed to provide a nominal 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 forms part of 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 conventional single-input-voltage transformer, the DV250P6S5 features a 0/240/415 V primary terminal arrangement, allowing the installer to select the appropriate primary connection for the available electrical supply. Its 0/240 V secondary terminals provide a single nominal 240 V AC output, making it a practical solution for industrial control circuits and auxiliary electrical equipment operating at this voltage.
With a rated apparent power of 250 VA, Class E insulation and 8% voltage regulation, the ETE DV250P6S5 offers dependable performance for appropriately sized control circuit loads. Its continuous-duty construction, IP20 touch-proof terminals, Class H varnish impregnation and dedicated core earth connection support integration into industrial electrical installations.
Measuring 120 × 88 × 120 mm and weighing 3.9 kg, the DV250P6S5 is designed for installation in electrical control cabinets and machinery panels. Its specified EPH 3 or EPN 2 enclosure references provide suitable enclosure options where additional physical protection is required.

The ETE DV250P6S5 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 features 0/240/415 V terminals, allowing the appropriate input connection to be selected during installation. When correctly connected to the matching primary voltage, the transformer provides a nominal 240 V AC secondary output through its 0/240 V secondary terminals.
This dual-input arrangement is particularly beneficial for OEM machinery manufacturers and electrical panel builders producing equipment for different industrial supply configurations. The DV250P6S5 can accommodate either supported primary voltage without requiring separate transformer models for each installation. When supplied from 415 V AC, it steps the voltage down to 240 V AC; when supplied from 240 V AC, it provides a nominal 240 V AC secondary supply through the transformer. The correct primary terminals must always be selected according to the available supply and the manufacturer's connection instructions.
The transformer's 250 VA continuous rating provides a calculated full-load secondary current of approximately 1.04 A at its nominal 240 V AC output. This calculation is based on the rated apparent power divided by the secondary voltage. When selecting the transformer, engineers should also consider the combined apparent power of connected devices, operating characteristics, permissible voltage variation and any short-duration inrush requirements.
The specified 8% voltage regulation describes the secondary voltage variation between no-load and rated-load conditions under the applicable test conditions. This characteristic is important when supplying contactors, relays and other control equipment with defined operating voltage tolerances. The nominal 240 V AC output should not be interpreted as a perfectly constant voltage under every loading condition.
The DV250P6S5 incorporates Class E insulation, 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 3 or EPN 2. Correct primary and secondary overcurrent protection, protective earthing, ventilation, cable sizing and mounting arrangements remain essential for safe and dependable operation.
