Product Description

Overview
The Yokogawa PW502 is a precision power supply module designed for the WE7000 series of PC-based measurement and data acquisition systems. It delivers stable, low-noise DC power to internal function modules, ensuring accurate high-speed measurements in industrial and laboratory environments. This module is built for reliability, durability, and EMI/EMC compliance, protecting sensitive data acquisition systems from electrical interference.

Key Performance Features

High Stability and Low Noise
The PW502 provides exceptionally clean DC power with minimal ripple, crucial for high-resolution analog-to-digital conversions. Its output maintains a high signal-to-noise ratio (SNR) for precision instrumentation, reducing measurement errors caused by electrical fluctuations.

Protection Mechanisms
The module includes robust safeguards to protect both the supply and connected equipment:

• Overvoltage Protection (OVP): Limits or shuts down output in case of excessive voltage.

• Overcurrent Protection (OCP): Prevents damage during short circuits or overload conditions.

• Thermal Protection: Monitors internal temperatures to prevent overheating during continuous operation.

Efficient Thermal Management
The PW502 is engineered for optimal heat dissipation, using chassis airflow to maintain safe operating temperatures. High conversion efficiency minimizes power loss, reducing thermal stress on the measurement rack.

Seamless Integration
Designed specifically for the WE7000 platform, the PW502 is plug-and-play and supports onboard status indicators, allowing technicians to monitor operational health instantly via LEDs for power and fault conditions.

Technical Specifications

Applications
The PW502 is ideal for laboratory and industrial measurement systems, high-speed data acquisition modules, and any application requiring low-noise, highly stable DC power. It is frequently used in research laboratories, QA testing stations, and industrial monitoring setups.
