SP-50405

The Allen Bradley SP-50405 discharge board serves as a crucial component in controlling the performance of Allen-Bradley 1334 drives. Designed for internal mounting within the drive assembly, this unit utilizes a solid-state power assembly for reliable operation.

Electrical connections are made through an edge connector and harness, ensuring a secure integration with the drive system. The voltage rating of this discharge board corresponds to the DC bus voltage of the 1334 series, allowing for seamless compatibility. A significant feature of the SP-50405 is its support for dynamic braking, made possible with an external braking resistor, which enhances the drive's braking capabilities.

In terms of safety, the discharge board is equipped with drive overvoltage protection, which safeguards the system from electrical surges. It demonstrates capabilities to handle a regeneration capacity of 30-50 HP during deceleration, making it suitable for various industrial applications.

The operational limits for the SP-50405 range from 0°C to 50°C, making it fit for standard industrial environments. Additionally, its humidity tolerance spans from 5% to 95% (non-condensing), ensuring reliability across different conditions. The cooling mechanism relies on forced-air cooling within the drive, aiding in maintaining optimal temperatures during extensive use. Constructed from FR4 epoxy, the board is designed to withstand the rigors of industrial applications, contributing to long-lasting performance and reliability.
