Speed Board Key benefits - Built-in reverse-power protection: prevents operation if input power is connected with reversed polarity, ensuring safe use and protecting downstream components. - Full-range speed control: output supports control from 0 (motor stopped) up to maximum speed, allowing precise regulation across the full operating range. - Flexible external control: accepts external control signals — either a ~5 V, 10 kHz pulse/PWM signal or a 0–5 V analog voltage — for easy integration with controllers, microcontrollers, or PLCs. - Broad applicability: designed for a wide range of industrial applications where reliable, simple speed control is required. What it does and why you need it - Protects equipment and personnel by disabling operation on reversed input voltage, reducing risk during installation and maintenance. - Provides consistent, repeatable speed control from fully stopped to top speed, enabling better process control, energy savings, and reduced mechanical stress. - Interoperates with common control standards (5 V PWM or 0–5 V analog), so you can connect typical industrial controllers or hobbyist microcontrollers without additional interface hardware. Compatibility and performance - Function: motor speed control with safe shutoff under reversed input polarity. - Control inputs supported: ~5 V 10 kHz pulse/PWM or 0–5 V voltage control. - Output behavior: full-range control from 0 to maximum motor speed. - Usage environment: suitable for a variety of industrial situations and control systems. Practical application examples - Conveyor speed regulation: integrate the Speed Board to adjust line speed smoothly from stop to maximum for material handling and packaging lines. - Ventilation and fan control: use PWM or 0–5 V control from a building automation system to set fan speeds for climate control applications. - Machine test benches and prototypes: connect to a microcontroller or PLC to run controlled motor-speed tests without adding extra interface electronics. Ordering note - Product name: Speed Board - Core functions: reversed-input protection, full-range speed output, compatible with ~5 V 10 kHz PWM or 0–5 V control signals.
