Allen Bradley 1391-T150DT Used Surplus

The Allen-Bradley 1391-T150DT isolation transformer has a 15-kVA rating. The 1391-T150DT transformer has a primary input voltage range of 240 to 480 Volts AC. This transformer belongs to the 1391 AC servo series from Allen-Bradley. It is a 3-phase device and it has an operating frequency of 60 Hertz. Isolation transformers like this one are mainly used to transfer electrical power from a source of AC power to another device while isolating the powered device from the main power source. The device should be used and stored within a relative humidity range of 5 to 95%, non-condensing. The input is protected against transient voltage. The device is equipped with a power line D/B contactor which opens the AC line to the drive and inserts a shunt regulator resistor across the DC bus when the contactor is de-energized.

The 1391B-ESAA15 transformer is equipped with a 2-line LCD screen and a programming panel. It is used to feed input and configure the device. The panel has 5 buttons and the LCD can display 2 lines and 16 characters of information at a time. Through the panel, the transformer can be troubleshooted when needed. The device has a patented current control implementation function. The transformer is controlled by using a microprocessor. The logic board houses the microprocessor and it can be easily removed and replaced for diagnostics and troubleshooting. The 1391B-ESAA15 transformer features true vector control. The device supports both linear acceleration and linear deceleration. It can be set by using the control module. Multiple LEDs are located on the front panel to show the status of the transformer.
