Product Description:
The PRS-1818 Servo Drive Board from Sanyo Denki is a compact and reliable motion control unit. It is designed for controlling servo motors in various automation systems. The board supports high current switching and signal isolation. It offers robust power regulation and thermal protection features for safe operation.
The PRS-1818 servo drive board includes multiple types of connectors for flexible integration. CN1–CN5 headers handle input and output signals. A 60 pin edge connector allows for motherboard or backplane interface. Additional 3–6 pin JST connectors manage signal and low voltage power lines. For main power connections, heavy gauge screw terminals and wire leads are used. The board's power section is equipped with large electrolytic capacitors rated at 220 µF, 200 V. Rectified input is filtered using these capacitors for stability. The custom transformers (TE-1983 SD2 and KK-11369) support a step down isolated supply. The power conversion uses a switching topology with a PWM controller IC likely operating in a flyback or forward mode. Output voltage is stabilized using inductors and capacitors. A Sanyo Denki C-5447 relay switches high current paths and operates with a 24 V or 48 V coil. Rectification is achieved using an RBV-606 bridge rectifier that is rated for 6 A and 600 V. Toroidal inductors help reduce noise in the output. Surge protection in the model is provided via MOVs or TVS diodes placed near the input.
Signal level isolation and control of the PRS-1818 servo drive board are handled by photo couplers. A precision potentiometer is included for gain tuning or offset calibration. The unit's design includes thermal management through an aluminum heat spreader that improves heat dissipation during operation.
Frequently Asked Questions about PRS-1818:
Q: What power conversion method does the PRS-1818 use for voltage regulation?
A: The PRS-1818 employs a switching topology controlled by a PWM controller IC. This design likely operates in flyback or forward mode to stabilize the output voltage.
Q: How does the PRS-1818 Servo Drive Board manage high current switching safely?
A: The PRS-1818 uses a Sanyo Denki C-5447 relay rated for 24 V or 48 V coils to switch high current paths. It also includes robust thermal protection to prevent overheating during operation.
Q: What role do the electrolytic capacitors play in the PRS-1818 servo drive board?
A: The board uses large 220 µF 200 V electrolytic capacitors to filter the rectified input voltage. This filtering ensures power stability and smooth operation of servo motors.
Q: How is signal isolation achieved in the PRS-1818 servo drive board?
A: Signal level isolation is handled by photo couplers in the PRS-1818. These components ensure reliable control signals while protecting the system from electrical noise.
Q: How does the PRS-1818 manage heat dissipation during extended use?
A: Thermal management is enhanced by an aluminum heat spreader in the PRS-1818 servo drive board. This component effectively dissipates heat to maintain safe operating temperatures.
