Overview
The Magpowr 3B117 tension control circuit board (model 31B117-1) is a specialized PCB module engineered for precision tension control in industrial automation systems. Magpowr, a division of Maxcess International, manufactures tension control solutions for magnetic particle clutches, hysteresis brakes, and pneumatic systems used in web handling, converting, and material processing industries. This module integrates into larger tension control assemblies to regulate current and torque output for clutches and brakes.
Key Features
- Compact PCB design optimized for industrial control enclosures
- Supports solid-state tension control applications
- Compatible with Magpowr magnetic particle clutches and brake systems
- Designed for reliable, repeatable performance in continuous-duty environments
- Jumper-selectable configurations for system flexibility
Technical Specifications
Specific electrical ratings and pinout details should be verified with the original system documentation or by contacting Magpowr technical support. General Magpowr tension control products operate in the following ranges:
- Power Supply: 24 VDC or 90 VDC (model-dependent)
- Output Current: Adjustable, typically 1/8 to 1 amp ranges
- Front Panel Control: Potentiometer adjustment with analog feedback
- Reverse Current Circuitry: Standard feature for enhanced controllability
- Application: Magnetic particle clutches, hysteresis brakes, web tension systems
Typical Applications
The Magpowr 3B117 PCB is used in:
- Web Handling: Paper, film, and label tension control during converting and printing
- Material Processing: Constant-torque regulation in unwind and rewind applications
- Automotive & Aerospace: Assembly line clutch and brake management
- Industrial Automation: Embedded control modules in larger tension management systems
- Textile & Converting: Dancer arm and follower arm control systems
