HDSP-F303 Application Field and Working Principle

The HDSP-F303 is a 7-segment numeric display module in the "Display Modules - LED Character and Numeric" category. It is a popular choice for many applications requiring a 7-segment display due to its large, bright 3mm LEDs, wide viewing angle and low power consumption.

Application Field

The HDSP-F303 is ideal for a variety of applications including industrial and control systems, instrumentation interfaces and LED displays for logic, alarm and status indication. It is perfect for use in harsh industrial environments due to its robust, durable construction and wide temperature range from -20 to +70 C. The HDSP-F303 also includes mounting holes for secure connection to the panel, and features a transparent protective lens.

Technical Specifications

The HDSP-F303 is powered by a 200-250VAC input with a 70mA maximum current and a power factor of 0.3 to 0.7. It has a 3mm fixed current LED display with a digit height of 12.7mm, and a wide viewing angle of 60°. The HDSP-F303 comes with an array of user-configurable features, including adjustable character width, height and spacing as well as single font and color selection.

Working Principle

The HDSP-F303 uses direct drive technology to generate 7-segment displays and operates at a much higher frequency than standard LED modules, resulting in an exceptionally bright display. The HDSP-F303 has an effective scan ratio of 50:1, a 5kHz default frame rate and a 7kHz to 20kHz adjustable frame rate, which provides a unique combination of performance and flexibility.The HDSP-F303 includes a data interface that contains up to 8-bits of serial data for each character. The data is clocked into the HDSP-F303 at a 5kHz default frame rate and can be adjusted to 7kHz to 20kHz. The HDSP-F303 can also be configured to use an analogue dimming signal with an adjustable brightness range.

Conclusion

The HDSP-F303 is an excellent choice for a range of applications requiring a 7-segment numeric display. Its sturdy construction and wide viewing angle make it suitable for use in harsh industrial environments, while its adjustable features make it easy to configure for different requirements. The direct drive technology and adjustable frame rate allow for an exceptionally bright display and its data interface provides great flexibility.
