Product Description:

The Sanyo Denki PRS-4348C Servo Drive Board is designed to be inserted and integrated into a system that requires constant and capable drive control and it has a constant power supply which is necessary in the seamless operation of the servo motor.

The PRS-4348C servo drive board compact electronic design makes it suitable to service where size is considered an important factor and upon its rating, it has a 120V AC at 60 Hz and a maximum consumption of 8 Watts. It facilitates a reliable power supply as it works at a current power of 0.3 amperes and it is significantly small that makes the positioning within limited control cabins flexible. The direct current output of this module is 12 volts DC at 300 milli amperes and the maximum output is 8 watts which allows adequate power to the drive system and the type of output is unregulated which delivers mainly uncompensated voltage. It is also available in a center positive sleeve connector polarity which is compatible with standard connector assemblies and has dimensions like 50.8 x 60.325 x 41.275 (mm) which allows effective use of space in automation assemblies. Its weight is constructed to be about 1 pound and this helps in decreasing the burden on mounting frames and it is UL listed which means it meets the mandatory safety certification.

This PRS-4348C servo drive board mounting style includes a compact barrel plug with LED indicator that allows clear status visibility and its electrical and mechanical specifications are designed for compatibility with standard servo components that rely on stable DC output. Its small shape and light weight enhances its flexibility of installation that favors configurations with limited space, and because of its safety approval and distinctly illuminated indicators, it can be relied upon and monitored.

Frequently Asked Questions about PRS-4348C:

Q: Why is the PRS-4348C designed with an unregulated output type?

A: The unregulated output reduces design complexity and improves efficiency for systems that already manage voltage stability. It also minimizes thermal management needs in low-voltage environments.

Q: How does the LED indicator on the PRS-4348C help during operation?

A: The LED provides instant visual confirmation that the board is powered and active. It assists technicians in quick diagnostics and maintenance checks.

Q: What is the benefit of the center positive sleeve connector in PRS-4348C?

A: The center positive sleeve ensures compatibility with standard DC jacks used in servo systems. It prevents reverse polarity connection errors during installation.

Q: Why is the 0.3 A current rating significant for the PRS-4348C Servo Drive Board?

A: The 0.3 A rating supports consistent low-power applications that require stable drive control. It is ideal for continuous-duty components in automation.

Q: How does the PRS-4348C compact size affect installation in control systems?

A: Its small dimensions allow integration in tight enclosures without altering system layout. This enables efficient use of space in control cabinets.
