PRS-3708C

The PRS-3708C from Sanyo Denki is a high-performance servo drive board in the PRS Servo Drive Boards series, engineered for demanding industrial automation environments. This panel-mounted drive accepts a wide input voltage range of 200–240 VAC and delivers a power rating of 1.5 kW for robust motor control. With a compact form factor and a mass between 5–10 kg, it strikes an ideal balance between power density and ease of installation. Designed to withstand temperatures from -10°C to +60°C, the PRS-3708C ensures reliable operation even under fluctuating environmental conditions. Its built-in protection features for overcurrent, overvoltage, and thermal events guarantee continued uptime in critical applications.

Featuring advanced electrical and control technologies, the PRS-3708C employs servo position & speed control in a sophisticated PWM architecture for precise motion management. The unit draws up to 9 A of input current and interfaces seamlessly via standard servo control signals. It accepts ±10 V analog inputs for direct control and offers RS-232/RS-485 connectivity for system integration. The drive’s internal interface supports high-resolution feedback loops, enabling smooth acceleration and deceleration profiles. Additionally, the integrated brake control function simplifies the attachment of electromagnetic brakes, providing immediate stopping power and enhanced safety.

Operational resilience is delivered through forced cooling method that maintains optimal thermal conditions during extended duty cycles. The PRS-3708C’s comprehensive protection features guard against overcurrent, overvoltage, and excessive temperature, safeguarding both drive and motor. Rated for ambient operation between -10°C and +60°C, it tolerates harsh factory environments with stable performance. Its compact mass of 5–10 kg facilitates mounting near motors or in control cabinets, reducing cable lengths and improving response times. Robust mechanical design and high-quality components provide long service intervals and minimal maintenance requirements.

Integration into automated systems is straightforward with the PRS-3708C’s panel mount format and standardized control interfaces. It supports firmware updates via USB or serial links, enabling quick deployment of feature enhancements and optimizations. The drive’s compatibility with Sanyo Denki software tools allows engineers to configure motion profiles, tune control loops, and monitor diagnostics in real time. Ideal for CNC machinery, robotic systems, and packaging lines, the PRS-3708C delivers precise, reliable performance across a broad range of industrial applications.
