The YOKOGAWA SPW481-53 is a high-reliability power supply module designed for industrial automation systems, delivering stable AC-to-DC power conversion for control equipment, data collectors, and field instruments. As part of Yokogawa’s OPREX measurement and automation portfolio, the SPW481-53 ensures consistent performance in harsh environments, making it ideal for critical applications in manufacturing, energy, and process control.
1. Product Description
The YOKOGAWA SPW481-53 is a standard power supply module (non-explosion-proof) engineered to provide regulated DC power for Yokogawa’s automation systems. It converts 100–120 V AC input (50/60 Hz) into a stable DC output, supporting devices such as PLCs, I/O modules, and field sensors. Key features include overload, overvoltage, and short-circuit protection, ensuring system safety. With a compact design (5.1 cm × 20.3 cm × 14.6 cm) and lightweight construction (0.9 kg), the SPW481-53 integrates seamlessly into industrial setups. Its wide operating temperature range (-20°C to 70°C) and compliance with ISA G3 environmental standards make it suitable for dusty or corrosive environments.
