TS and TTS series General purpose, single phase (TS) and three phase (TTS), double wound, enclosed type transformer assemblies, rated from 2.5 to 25 kVA single-phase and from 1 to 25 kVA three phase.

Designed for installation in plant rooms, workshops, etc., TS and TTS 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 or 2mm sheet steel with a durable paint finish, shade Dark Admiralty Grey. Wall mounting enclosures are available for ratings up to 4 kVA single-phase, vented to IP21 or non-vented to IP44. Enclosures for all other ratings of single phase transformer and for all three phase transformers are floor standing and are vented to IP21.

Single phase, continuously rated from 2.5 to 25 kVA.
Three phase, continuously rated from 1 to 25 kVA.
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 – 24, 25, 42, 50, 110, 230 and 400 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 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 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.

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