Wall mounting transformers with a wide range of voltage ratios and ratings up to 2kVA, housed in steel 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.

TLW series General purpose, single phase, double wound, enclosed type transformer assemblies, rated from 100VA to 2000VA.

Designed for installation in plant rooms, workshops, etc., TLW 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.

Fabricated from 1.5mm sheet steel with a durable paint finish, shade Dark Admiralty Grey. Enclosures are wall mounting and can be supplied vented to IP21 and IP23 or non-vented to IP44. The wall mounting brackets can be repositioned on site to make the enclosure floor mounting.

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

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 winding will proportionally vary the secondary voltage and also alter the inrush current characteristics. To address the impact of supply voltage variations, voltage tappings can be incorporated into the primary winding. We would be pleased to quote for transformers with primary tappings.

Transformers with dual secondary windings can be supplied i.e. to feed a power tool at 110 volts and an inspection lamp at 24 volts. The earth connection of the secondary winding must be specified – PTO for guidance on the earthing of transformer windings.

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