Mains Isolation Transformer with Stepup Windings
LL1662
LL1662 is a C-core mains transformer for isolation and DC current elimination. The core is assembled with a
carefully selected, very small air-gap to compensate for any mains DC-unbalance. Additional two windings of
10V each are provided to compensate for voltage drop and low mains voltage.
Estimated power rating 300 VA, which can be increased with good cooling.
