1395-B75-D3-P11-P51-X1

The Allen Bradley part number 1395-B75-D3-P11-P51-X1 represents a sophisticated microprocessor-controlled DC drive engineered for high performance. Designed to facilitate advanced control processes, this drive boasts a continuous output power of 75 HP in a regenerative mode, which enhances energy efficiency. The device operates with a supply voltage ranging from 150 to 460 VAC, utilizing a 3-phase power configuration. For auxiliary control, the device accepts a 115 VAC power input on a single phase.

This drive comes with several features to enhance functionality. It includes a designated 24 VDC discrete adapter for Port A, while Port B is versatile with a multi-communication adapter option. The auxiliary relay comprises one normally open and one normally closed dry contact for additional control management.

Equipped with four analog inputs rated at ±10 VDC, the 1395-B75 also includes four digital inputs that can accept either 24 VDC or 120 VAC signals, making it adaptable for various applications. Speed regulation is notably tight, achieving an exceptional accuracy of 0001% over a range of 100:1. The drive incorporates an encoder with dual channels operating at 1025 kHz to ensure precise motion control.

The armature power section design employs a full-wave regenerative setup using 12 silicon-controlled rectifiers (SCR), capable of handling a maximum DC output voltage of 500 VDC. With a dynamic braking feature supporting 75 to 100 HP and an overload capability of 150% for up to 60 seconds, this drive is built to withstand demanding operational conditions.
