1395-B77-C4-P11-P51

Designed as a digital DC drive, the 1395-B77-C4-P11-P51 from Allen Bradley exhibits significant capabilities for complex applications. It achieves a maximum output power of 125 HP while supporting regenerative operations effectively. The operating input supply voltage range spans from 150 VAC to 460 VAC in a three-phase configuration, accommodating various industrial systems.

Users will find 10 digital inputs and 5 digital outputs, all rated at 24 VDC, making it suitable for diverse control tasks. Additionally, the drive offers four differential analog inputs with a range of ±10 VDC for precise signal processing. The armature firing topology consists of a 12-SCR full-wave regenerative bridge, ensuring efficient motor control.

Port A features a 24 VDC discrete adapter, while Port B is equipped for multi-communication through an RIO/DH+ adapter. The output armature voltage is set at 500 VDC, with an impressive output armature current rating of 980 A, allowing for extensive operational demands.

The exposed chassis design promotes effective cooling, while the overload capacity guarantees that the drive can handle transient surge conditions—150% for one minute and 200% for ten seconds. The internal field supply is regulated by a single-phase SCR regulator, with a field voltage range between 240 to 300 VDC. This drive is integrated with a standard contactor suitable for applications ranging from 125 to 150 HP, offering a complete solution for advanced DC drive systems.
