1395-B76-D3-P10-P50-X1

The 1395-B76-D3-P10-P50-X1 model from Allen Bradley represents a digital DC drive optimized for a range of applications. With the ability to manage power levels efficiently, this drive includes a regenerative horsepower rating of 100 HP while featuring a dynamic braking system suited for 75 to 100 HP operations.

It utilizes an RS-422 programming interface, facilitating straightforward communication with other devices and systems. The drive incorporates four digital inputs that can operate at either 24 VDC or 120 VAC, thereby ensuring versatility in control signals. Additionally, it has two dry contact relay outputs for basic signaling.

For analog interfacing, this drive supports four inputs and outputs, each rated at ±10 VDC, catering to modern control system requirements. The input voltage is designed for a three-phase supply within the range of 380 to 460 VAC. The device also operates at input frequencies of either 50 or 60 Hz, enhancing its adaptability.

On the output side, this drive provides a nominal output voltage of 500 VDC while being capable of delivering a maximum current of 980 A. The armature firing mechanism utilizes a 6-pulse full-wave NEMA Code C approach, contributing to its efficiency.

For overload protection, the unit can handle up to 150% of its rated capacity for a duration of one minute and can withstand 200% for ten seconds, ensuring reliable performance during transient conditions. Additionally, it boasts an impressive speed regulation accuracy of 0.01% of the set speed when using an encoder. The field voltage operates within a range of 240 to 300 VDC, further expanding the operational capabilities of this drive.
