Portable transformers with a wide range of voltage ratios and ratings up to 3kVA, housed in insulated enclosures, fitted with sockets, MCBs, etc., made to order. If you would like to discuss a bespoke transformer, please click on the Enquire button, forward your details and we will contact you to discuss your requirements.

ITU series General purpose, single phase, double wound, transformer assemblies rated from 100VA to 3000VA, housed in robust, portable GRP enclosures, compound filled. As standard, ITU series transformers are of Class 1 construction and require an incoming protective conductor.

Applications
Designed for use in portable applications or damp environments, ITU series transformers are available in a wide range of power ratings and voltage ratios and can incorporate a variety of fitments including MCBs, RCDs, Fusegear, Sockets and Isolators.

Enclosures
Portable pattern with stout carrying handle, ITU series enclosures are moulded from high impact resistant GRP, standard colour yellow – other colours available to order. Enclosures are non-vented and have an IP55 rating (the overall IP rating of the assembly may be governed by external fitments, such as socket outlets).

Ratings
Single phase, continuously rated at 100VA, 150VA, 200VA, 250VA, 350VA, 500VA, 750VA, 1000VA, 1500VA, 2000VA and 3000VA.
Transformer windings are designed and manufactured in accordance with BS EN 61558 Parts 1, 2-4, 2-6 and 2-23, as applicable.

Voltages
Primary Voltages – 230 and 400 volts
Secondary Voltages – 12, 24, 25, 42, 50, 110 and 230 volts

BS7671:2018 permits a supply voltage tolerance of -6% / +10%. Any variation in the voltage connected to the primary of the transformer will proportionally vary the secondary voltage and also alter the inrush current characteristics. To address the impact of supply voltage variation, voltage tappings can be incorporated into the primary winding. We would be pleased to quote for transformers with multiple primary tappings.

Transformers with dual secondary windings are available to feed power tools at 110 volts and inspection lamps at 24 volts. The earthing arrangement of secondary windings must be specified. PTO for guidance on the earthing of transformer windings.

Fitments
ITU series transformers can be fitted with a wide combination of MCBs, RCDs, Fusegear, Sockets and Switch Disconnectors. Our Customer Service Centres would be pleased to quote against your specific requirements.
