Why Choose the ETE DV50P6S5 50 VA Dual-Input Control Transformer?
The ETE DV50P6S5 is a compact and versatile 50 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 model belongs to the established ETE DV dual-input-voltage stock control transformer range, developed for electrical panel builders, OEM machinery manufacturers and industrial automation applications requiring flexible primary voltage connections.
Unlike a single-input-voltage transformer, the DV50P6S5 features a 0/240/415 V primary terminal arrangement, allowing the installer to select the appropriate primary connection for the available supply. Its 0/240 V secondary terminals provide a single nominal 240 V AC output. This dual-input design offers flexibility when specifying equipment for different industrial electrical installations without requiring separate transformer models for each supported primary voltage.
With a 50 VA continuous rating, Class E insulation and 15% voltage regulation, the ETE DV50P6S5 is suited to appropriately rated control and auxiliary circuits. Its compact dimensions of 75 × 71 × 88 mm, weight of just 1.2 kg and specified EPH 1 or EPN 1 enclosure references make it a practical choice for space-conscious electrical control panels and industrial equipment.

The ETE DV50P6S5 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 appropriate primary connection to be selected during installation. When correctly connected to the matching supply voltage, the transformer provides a nominal 240 V AC secondary output through its 0/240 V secondary terminals.
This dual-input arrangement is particularly useful for machinery manufacturers and panel builders producing equipment for different electrical supply configurations. Rather than selecting separate transformers for 240 V AC and 415 V AC applications, the DV50P6S5 supports both specified input voltages through its primary terminal selection. Only the appropriate primary connection should be used for the available supply, following the manufacturer's wiring instructions.
The transformer's 50 VA apparent power rating provides a calculated full-load secondary current of approximately 0.21 A at 240 V AC. This makes the DV50P6S5 suitable for appropriately rated auxiliary and control loads. The total connected apparent power, operating characteristics and any short-duration inrush requirements must be considered when determining whether the transformer has sufficient capacity.
The specified 15% voltage regulation describes the transformer's secondary voltage variation between no-load and rated-load conditions under the applicable test conditions. This is an important consideration for equipment with restricted voltage tolerances. A nominal 240 V AC output does not mean the secondary voltage will remain exactly 240 V under every operating condition.
For straightforward installation, the DV50P6S5 combines compact dimensions with IP20 touch-proof terminals, a dedicated core earth connection and an available DIN rail mounting option. Where an enclosure is required, the specified references are EPH 1 or EPN 1. Suitable primary and secondary circuit protection, protective earthing, ventilation and compliance with relevant electrical installation requirements remain essential.
