1395-B74-C2-P10-P50-X1

The Allen Bradley 1395-B74-C2-P10-P50-X1 is a digital DC drive that offers an advanced solution for controlling DC motors in various industrial environments. It operates with a full-wave regenerative power structure, utilizing 12 silicon-controlled rectifiers (SCR) and featuring 1-phase field regulation. The drive includes an RS-422 communication port for integration into control systems.

This model supports five preset speeds as well as two jog speeds to enhance operational flexibility. Users can independently adjust acceleration and deceleration times ranging from 0.1 seconds to 6554 seconds according to application needs. Feedback can be obtained through either an incremental encoder, providing 12V and 102.5 kHz, or a DC tachometer, offering versatile setup options.

For input and output capabilities, the drive provides four analog inputs and outputs, each at ±10V, alongside four digital inputs that support either 24VDC or 120VAC, complemented by two relay outputs. When connected to an AC input range of 150 to 460 VAC (three-phase), the drive retains a control voltage of 115 VAC ±10%. The motor can achieve output voltages of 240, 400, or 500 VDC based on the input voltage configuration.

Designed for continuous operation, the 1395-B74-C2-P10-P50-X1 handles motor power ratings from 1 to 600 HP, with the exact rating depending on the selected voltage. This drive maintains a current range from 3.6 to 980 A in continuous applications. The field excitation requirement ranges from 120 V to 300 VDC at a capacity of 0.15 to 40 A, accepting both internal and external supply options.

For overload situations, the drive is engineered to support capacities of 150% for one minute, 200% for ten seconds, and 260% for five seconds. Its speed regulation accuracy is impressive, achieving 0.01% with encoder feedback, 0.5% with tachometer feedback, and 2% based on arm voltage, providing users with precision control in various operating conditions.
