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 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 […]
Four life cycle stages proposed by the US EPA for “wire and cable”, plus one additional stage related to electromagnetic core and coil assemblies.
When sizing a reduced duty cycle transformer, here are important facts to keep in mind.
Saturable reactors are considered magnetic amplifiers because they can use a relatively small amount of DC volt-amps to control the transfer of a significant amount of AC volt-amps.
