1395-B76-D3-P12-P50

The Allen Bradley 1395-B76-D3-P12-P50 is a sophisticated microprocessor digital DC drive tailored for advanced motor control. It employs a robust power bridge topology that is fully regenerative and consists of twelve silicon-controlled rectifiers (SCR). The output voltage can be adjusted to 240, 400, or 500 VDC, depending on the input level supplied. This drive is designed to deliver a continuous output current that varies between 36 and 980 Amps, ensuring flexibility for different applications.

The drive features exceptional speed regulation capabilities, with an accuracy of just 0.001% of the base speed when an encoder is utilized. For connectivity and configuration, it includes an RS-422 programming port. The drive supports four discrete inputs, which can operate at either 24 VDC or 120 VAC, all of which are isolated to prevent interference. It can also provide two dry relay outputs rated at 2A up to 30 VDC.

In terms of analog interfacing, the unit supports four inputs and outputs, all rated at ±10 VDC, allowing for various control and feedback mechanisms. The maximum field current supported by this drive is 40 Amps, and it outputs a regulated field voltage ranging from 120 to 300 VDC. The drive is capable of handling overload conditions, managing up to 150% of rated capacity for 60 seconds and 200% for 10 seconds, which enhances its adaptability in peak load situations.

With a horsepower rating of 100 HP in regenerative applications, the drive is suitable for driving applications requiring high power levels. It employs a dynamic braking contactor suited for motor ratings between 75 and 100 HP, allowing for effective stopping capabilities. Overall, the 1395-B76-D3-P12-P50 is built to operate with an input voltage of 150 to 460 VAC across three phases, offering a total tolerance of ±10% for stable operation.
