Product Overview
The document provides detailed information on stepper motor controls, specifically the SA4505 and SA4510 models. These products are designed for robust performance in various applications, featuring a rugged miniature aluminum case, multiple mounting options, and tool-free power terminal strip installation.

Technical Specifications

• SA4505: Operates with a power supply voltage of 11-48 VDC, nominal current of 5 A, and maximum power of 250 W with a heatsink. It supports micro-stepping up to 1/16 and includes features like over-current and over-temperature protection.
• SA4510: Similar to the SA4505 but with a nominal current of 10 A and maximum power of 500 W with a heatsink. It also supports micro-stepping up to 1/16 and includes the same protective features.

Control Inputs and Outputs
Both models feature optical control inputs for enable, direction, and step functions, with a speed control input (Spdext) ranging from +1 to +5 VDC. Outputs include a +5 V auxiliary voltage source and an error signal.

Mechanical and Environmental Data
The dimensions for both models are approximately 119 x 85 x 27.5 mm, with a weight of around 220 g. They operate within a temperature range of -10 to +45°C and can be stored between -40 to +85°C. The humidity range is 20-80% relative, non-condensing.

Global Presence
