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.
