Osborne #13937T324 – High Impedance

Osborne’s #13937T324 high impedance transformer has a 480 Volt, 60 Hertz input and a no-load output voltage of 600 Volts. Should the insulation of the motorette under test fail in a shorted condition, the impedance of this transformer has been calibrated to limit the short circuit current to the motorette to 11 Amps RMS. The […]

Osborne #13936T324 – High Impedance

Osborne #13936T324 high impedance transformer has a 480 Volt, 60 Hertz primary and a no-load output of 120 Volts. Should the insulation of the motorette under test fail in a shorted condition, the impedance of this transformer has been calibrated to limit the shorted output current to 10 Amps RMS. The 120 Volt output is […]
