For opposite rotation interchange

connections from 1 to 2 and 4 to 5.

The isolated variable transformer has a separate primary wind­ing which is electrically isolated from the secondary or output
winding. Either side of the output can be grounded indepen­dently of the supply line, making them safe for all industrial,
classroom, and laboratory applications where an isolated out­put without a common ground connection is required.

The isolated units are designed for 120V, 50/60Hz input, and

the output voltages will vary from 0 - 122% of the input for a 0­140 volt output. Three sizes are available — J201B rated at 2
amps, J401 rated at 4 amps, and J901 rated at 9 amps.These
units are each available in the uncased design for bench or
back-of-panel mounting, and the shaft is adjustable to accom­modate various panel thicknesses. Dial plates supplied are 0­100%. The J201B and J401 are also provided in the 3PN plug
and cord series with and without voltmeter or ammeter.
