Control transformers generally conform to BS EN61558
for power supply in control circuits, distribution circuits, Control panels and drives
Isolation transformer generally conform to BS EN61558
For general purpose with double wound isolation and earth screen
Safety isolation transformer generally conform to BS EN61558
For general purpose with double wound isolation and earth screen with a max safety ref to earth voltage of 55V.
Auto Wound transformers generally to BS EN61558
Comprising of a single tapped winding with shared common, no primary and secondary isolation so not suitable for applications without in circuit protection.
Our standard range of robust enclosed transformers are available to any given IP rating, material and finish.
Our standard enclosures are Mild steel and finished to either Hammer grey or RAL 7032, IP21 as standard. Please note that for transformers enclosed above IP44 this data sheet is not applicable, please contact our engineers for physical dimensions
This range fulfills the requirements of control, safety and isolating transformers. Inrush currents and short circuit characteristics of ATL's transformers conform to up to date legislation and are compatible with all reputable manufacturers' switches breakers and magnetic release devices. All of our products are bespoke therefore voltages must be specified at enquiry stage. The transformers have protection against humidity and vibration. Our finger proof block terminals are shock proof and conform to BS EN & UL standards, other termination available please specify at enquiry stage. All of our transformers come complete with multiple footprints fixing centre's to enable a varied range of mounting configurations ref data sheet table.
