Product Summary

The Yokogawa PW482-50 is a robust power supply module for industrial automation systems. It accepts a 220-240 V AC input voltage with a ±10% tolerance. This module operates reliably across a wide temperature range from -20°C to 70°C. Its standard design offers no explosion protection for general-purpose use. The unit ensures stable power delivery with a maximum consumption of 230 VA.

Product Procurement & Buyer Guide

Selecting the correct power supply module is critical for system stability. The PW482-50 provides a dedicated solution for 220-240 V AC applications. This module is the basic type with standard explosion protection flags. You must verify your system voltage matches the 220-240 V AC requirement. The unit operates at either 50 Hz or 60 Hz with a ±3 Hz tolerance. This flexibility makes it suitable for global installations.

Procurement managers value the module's lightweight design at approximately 1 kg. This weight simplifies shipping and reduces logistical costs. The exclusive connector interface ensures a secure and reliable connection. You will not need to source additional adapters for standard Yokogawa racks. This module is an exact replacement for specific Yokogawa system configurations.

Application engineers benefit from the wide ambient temperature tolerance. The PW482-50 functions correctly from -20°C to 70°C. This range suits harsh industrial environments near furnaces or chillers. The maximum power consumption of 230 VA allows for efficient energy budgeting. You can plan your overall system power draw with confidence. This module integrates seamlessly into existing Yokogawa CENTUM or ProSafe-RS systems.

Step-by-Step User & Installation Guide

Follow these steps for a safe and correct installation of the PW482-50 module. Always disconnect all power sources before beginning any work. Verify that your input voltage is within the 220-240 V AC range. Confirm the frequency is either 50 Hz or 60 Hz with a ±3 Hz tolerance.

First, mount the module into the designated slot within your Yokogawa rack. Ensure the module slides in smoothly without any resistance. Secure the module using the provided locking screws at the top and bottom. This prevents vibration from dislodging the unit during operation.

Second, connect the input power cable to the exclusive connector interface. Use only the specified Yokogawa connector for this purpose. Ensure the connection is tight to prevent arcing or power loss. Do not apply power until all connections are verified.

Third, confirm the output connection to the backplane is fully seated. The module provides power to the rack through this connection. Check that the module's status LED illuminates after power application. A steady green light indicates normal operation. If the light is off, recheck all power connections immediately.
