Twin secondary windings may be connected in series or parallel or used independently.

  • Very Small size and low weight compared with traditional stacked lamination types.

  • Extremely low level of radiated magnetic field

  • Very low induced noise (hum)

  • Very low iron loss.

  • Double insulated primary leads.

  • Supplied with mounting kit.

  • 100% electrical and flash tested

  • High quality manufacturing and testing in accordance to EN61558, EN60742, EN60950, EN60065, VDE0551, VDE0550 and BS415

  • Tested and Approved by KEMA to EN61558. Click here for more info

  • UL Recognised to UL506, under family approval file E215495

 

Important Installation Note
Each transformer is supplied with a resin centre, with through-hole for single bolt fixing.
Under no circumstances should both ends of the fixing bolt contact a metal chassis or frame as this would create a 'shorted turn' causing irreparable damage.
