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.
