COO (Country of Origin):: PL

Open Form Toroidal Transformers, 115-230Vac Primary, 30VA & 50VA

Small size and low weight compared with traditional stacked laminated transformers

Both primary and secondary windings may be connected in series or parallel

Low induced noise (hum)

Low level of radiated magnetic field

Flexible leadouts, for ease of installation

100% electrical and flash testing

Warning

Under no circumstances should both ends of the fixing bolt simultaneously contact the metal chassis or framework as this would create a potentially dangerous 'shorted-turn'.

Approvals

CE marked, UL506, UL1411 and UL478

Standards

EN61558, IEC742

Supplied with

Full mounting kit
