Allen-Bradley 1391-T100ET AC Servo Controller

The Allen - Bradley 1391-T100ET is an isolation transformer for bulletin 1391 controllers. It meets the controllers' power needs of three - phase 230V AC and 35.5V AC single - phase.

All 1391 series controllers are sensitive to 35.5V AC on the logic control board. The 1391-T100ET has a 10.0 kVA rating. It can be connected to 240/380/415/480V AC on the input side. Up to four controllers can be connected on the output side with four 35.5V AC C.T. windings.

1391-T100ET has single - phase powering, ensuring efficient power delivery and galvanic isolation. This reduces risks to output devices from overcurrents and failures. For protection, there's a 115V AC thermal switch (P1 and P2). It opens at 185°C (±5°C) to prevent overheating damage.The transformer's dimensions are 12.00 in (305 mm) x 12.50 in (317 mm) x 16.00 in (406 mm). It weighs about 140 pounds (63.6 kg). Power dissipation is 100W at 20% rated power output and 500W at full power.

To get a NEMA Type 1 enclosure rating, pair it with a 1391 - TA2 Transformer Enclosure Kit.
