Configured for industrial automation stability, the YOKOGAWA PS35*A (PS35*A) is a high-performance power supply module designed to convert AC input voltage into regulated DC output for control systems. This hardware component ensures consistent power distribution and includes built-in protective features to maintain system integrity in demanding industrial environments.

Hardware Specifications

*Note: Weight specifications may vary depending on the specific assembly or regional distribution version. Always verify against your product label.

Power Management and System Protection

The PS35*A is engineered to provide a steady DC supply required for sensitive PLC and DCS components. Its design focuses on high reliability, featuring overcurrent, overvoltage, and short-circuit protection to prevent cascading system failures. The high Mean Time Between Failures (MTBF) rating and wide operating temperature range make it suitable for cabinet installations where environmental conditions might fluctuate.

Frequently Asked Questions (FAQ)

Q: Can the PS35*A be used in high-vibration areas?

A: Yes, the module is built for industrial use; however, it should be mounted securely on a standard DIN rail or panel according to the cabinet installation guidelines to minimize mechanical stress on the electrical terminals.

Q: Does this module require an external cooling fan?

A: The PS35*A typically relies on natural air convection. Ensure that you maintain adequate clearance (usually at least 50 mm) above and below the unit in the cabinet to facilitate proper airflow and thermal dissipation.

Field Installation Guidelines

• Input Wiring: Ensure the AC input is routed through a correctly sized circuit breaker or fuse. Use stranded, high-conductivity wire and verify all terminal connections are torqued to manufacturer specifications to prevent overheating.
• Grounding: Bond the module chassis to the system's protective earth (PE) bus. A solid ground connection is mandatory to ensure the unit’s noise suppression and safety isolation features perform as intended.
• Output Load: Ensure the continuous load does not exceed the 3.5 A rated current. If your application approaches this limit, consider calculating the heat derating based on the cabinet's internal ambient temperature.
• Regular Inspection: Periodically check the terminal block connections for signs of oxidation, especially if the module is installed in an environment with high humidity or corrosive trace gases.
