PCB, 2x115V, 1.6-50VA, UL

High quality low profile encapsulated toroidal transformers with two 115V, 50/60Hz primary windings suitable for connection in series to 230V supply, or parallel to 115V supply. Twin secondary windings may be connected in series, parallel or used independently.

LR   VDE   High quality Toroidal Transformers - fully encapsulated
 
When compared with conventional PC transformers, this series of toroidal transformers offer many distinct advantages:    
 
  • 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
  • 100% electrical and flash tested
  • High quality manufacturing and testing in accordance to:
    EN61558, EN60742, EN60950, EN60065, VDE0551, VDE0550 and BS415
  • UL Recognised to UL506

Primary-Secondary test voltage 4.0 KV (VDE0550).
Primaries and secondaries for parallel or series hook-up.
Ambient operating temperature 60°C maximum.
Insulation Class A (105°C)


Connections

For 230-volt operation, connect primaries in series by connecting pins 5 & 4 together and apply 230 volts across pins 6 & 3.
For 115-volt operation, connect primaries in parallel by connecting pins 6 & 4 together and pins 5 & 3 together; apply 115 volts across pins 6 & 5.
To parallel the secondaries, connect pins 14 to 12 and 13 to 11 take the output across pins 14 and 13.
To place the secondaries in series, connect pins 13 to 12 and take the output across pins 14 and 11.
