YOKOGAWA PW482-11

2. Product introduction

The YOKOGAWA PW482-11 is a specialized industrial dual-input power supply designed to deliver stable 12V DC power to low-voltage automation equipment. Building on the dual-input flexibility of the PW482-10 S2, it caters to systems requiring lower voltage but higher current than 24V DC solutions, making it ideal for powering sensitive electronics in industrial environments.

With a total output current of 15A (7.5A per channel in dual output mode), this power supply is well-suited for devices like high-resolution cameras, touchscreen HMIs (such as the F3PU20-0N), and communication modules (including the ISC40G-TF-T1-05 switch). Its 1+1 redundancy support ensures uninterrupted power to critical low-voltage components, even if one supply unit fails. The PW482-11 operates reliably in temperatures ranging from -15°C to 70°C, making it suitable for industries such as electronics manufacturing, precision instrumentation, and automated inspection systems. As a dedicated low-voltage power solution, the YOKOGAWA PW482-11 ensures consistent performance of sensitive equipment, reducing the risk of data loss or operational errors caused by voltage fluctuations.

3. Core advantages and technical highlights

12V low-voltage precision power:

Unlike the 24V-focused PW482-10 S2, the PW482-11 delivers stable 12V DC power with ±0.6% regulation, critical for sensitive electronics. In a semiconductor inspection system, it powers high-resolution cameras and image processing modules, ensuring consistent image quality by eliminating voltage ripple that could distort pixel data. This precision prevents false defect detection, which is crucial for maintaining yield rates in semiconductor manufacturing.

Higher current capacity for low-voltage devices:

With 15A total output (7.5A per channel), the PW482-11 can power multiple low-voltage devices simultaneously. In a smart factory’s HMI cluster, it supplies power to four F3PU20-0N touchscreens and associated communication modules (connected via the ISC40G-TF-T1-05 switch) without overloading. This eliminates the need for multiple smaller power supplies, simplifying cabinet design and reducing wiring complexity.

Optimized for low-power device compatibility:

The PW482-11 features a low no-load power consumption of <0.5W, making it ideal for systems with idle-mode devices. In a laboratory automation setup, it efficiently powers equipment that cycles between active and standby modes (such as sample handlers and analytical instruments), reducing energy waste during idle periods. Its soft-start capability prevents inrush current spikes that could damage delicate sensors, ensuring longer lifespan for connected devices.

Enhanced thermal management:

Equipped with a variable-speed fan and optimized heat sink design, the PW482-11 maintains stable operation even at high loads. In a closed control cabinet housing multiple heat-generating components, the fan adjusts speed based on internal temperature, minimizing noise while ensuring adequate cooling. This thermal efficiency allows it to operate at 100% load in 70°C environments without derating, a critical advantage in high-temperature industrial settings.

4. Typical application scenarios

In an electronics assembly line’s automated optical inspection (AOI) system, the PW482-11 powers high-resolution cameras, LED lighting arrays, and image processing units. Its stable 12V output ensures consistent image capture, allowing the system to detect tiny solder defects on circuit boards. During AC power fluctuations, the supply switches seamlessly to DC from a backup battery, preventing inspection interruptions that could halt production. The power supply’s low EMI emissions prevent interference with the AOI system’s sensitive sensors, ensuring accurate defect detection.

In a broadcast studio’s video production switcher system, the PW482-11 provides power to video processing modules and control panels. Its dual-input design allows operation on studio AC power during normal use and switches to DC from an uninterruptible power supply (UPS) during outages, preventing live broadcast interruptions. The supply’s low noise output ensures clean power to audio/video components, eliminating hum or signal distortion that could affect broadcast quality.

In a medical device manufacturing cleanroom, the PW482-11 powers precision robotics and vision systems used in catheter assembly. Its 12V output with tight regulation ensures the robotics maintain sub-millimeter positioning accuracy, critical for attaching tiny components. The power supply’s compliance with medical-grade EMI standards prevents interference with sensitive measurement equipment, ensuring product quality and regulatory compliance.

6. Installation, commissioning and maintenance instructions

Installation preparation

Before installing the PW482-11, ensure the mounting location has at least 120mm clearance for ventilation, with ambient temperature within -15°C to 70°C. Prepare tools including a torque screwdriver (2.5-3.5Nm), wire strippers, and a precision multimeter.

For AC input, verify 100-240V AC and install a 6A circuit breaker. For DC input, ensure 24-60V DC and use a 4A breaker. Use 4mm² cables for output connections to handle 15A current, with color-coded wiring to distinguish 12V, 0V, and ground. In redundant configurations, connect two PW482-11 units to the RBPW-01 module, with separate input sources for maximum reliability. Ground the unit using a 4mm² wire connected to the cabinet’s PE terminal to minimize noise.

Maintenance suggestions

Perform monthly visual inspections of the PW482-11 to check for loose connections, dust accumulation, or fan obstruction. Clean air intakes with compressed air every two months, or more frequently in dusty environments, to maintain airflow. Monitor output voltage biweekly using a precision multimeter, ensuring it remains within 12V ±0.6%.

Check status indicators weekly: a steady green LED indicates normal operation, while flashing or red LEDs signal faults (e.g., overtemperature, overcurrent). Test the variable-speed fan by applying full load and confirming the fan accelerates appropriately. Calibrate output voltage annually using the built-in trim potentiometer (if needed) to maintain regulation accuracy.

If a fault occurs, first check for short circuits in connected devices (e.g., F3PU20-0N HMI) before replacing the power supply. In redundant setups, use the RBPW-01 module to hot-swap the PW482-11 without interrupting power to critical equipment, minimizing downtime.
