About 1391-T050DT
The Allen-Bradley 1391-T050DT isolation transformer is a 5 kVA rated isolation transformer. It is designed for use with Allen-Bradley 1391B-ES servo controllers. In order to maintain the UL listing on Allen-Bradley 1391B-ES controllers, the users must provide power to the 1391B-ES controllers from an Allen-Bradley 1391 isolation transformer. The use of other transformers voids the UL listing. The Allen-Bradley 1391B-ES controllers are available in 15, 22.5, and 45 Amps current ratings. The complete servo system comprises a 1391B-ES controller, a 1391 transformer, a 1326 servo motor, and 1326 cables.
The 1391-T050DT isolation transformer is rated for 5.0 kVA. The primary voltage for the transformer is 240 to 480 Volts AC. The input is 3-phase and the supported line frequency is 60 Hertz. The secondary voltage for the transformer is 3-phase 230 Volts AC voltage. The secondary voltage also includes four 36 Volts AC single-phase rated windings. The 36 Volts AC output on the transformer is used to provide power to the logic control board on the 1391B-ES controller. The 36 Volts AC leads are connected to terminals 19 and 21 on Terminal Block 4 of the controller. The center tap is connected to terminal 20 of Terminal Block 4. The power dissipation for the 1391-T050DT isolation transformer at 20, 40, 60, 80, and 100% rated output is 50, 100, 150, 200, and 250 Watts, respectively. The weight of the 1391-T050DT isolation transformer is 100 pounds and it measures 11 x 14 x 11 inches. The ambient air temperature around the 1391-T050DT isolation transformer must be kept between 0 and 60 degrees Celsius and the relative humidity should be between 5 and 95% (non-condensing).
Technical Description of 1391-T050DT
The Allen-Bradley 1391-T050DT has a 240/480V AC Primary Voltage, 3 Phases, and a 60 Hz Frequency. It also contains a 230V AC Single-Phase C.T. Windings Secondary Voltage.

Maliha was wonderful. She got everything right the first try, formalized the quote and emailed it to me. The heavy lifting was done. I took care of ordering, address payment etc. Your website/portal was unusually easy to navigate (even by me).
Great experience from soup to nuts.

Texnite provided a power supply module which saved our NYC power plant customer from an emergency outage. We placed our order late in the afternoon. Even though it was well past their same day shipping cutoff time, Texnite still made an extra effort to ship our order immediately and the module arrived before 8am the following morning.
