Panel transformers come in many shapes and sizes. For convenience Express Transformers & Controls (2015) Limited has a standard range of products, details of which can be found below. In addition we can manufacture any transformer you require of similar power within the same size constraints.
Standard Models
Express Transformers & Controls (2015) Ltd manufacture a range of 46 transformers from 50 VA to 2500 VA that conform to BS EN61558 available with harmonised primary voltages of 0-220-230-240 volts or 0-380-400-415 volts and secondary voltages of 24 to 230 volts all with a centre tap.
All transformers incorporate a touch-proof terminal system approved by UL, CSA, VDE, etc.
