PW701 | Yokogawa | Power Supply Module

The Yokogawa PW701 power supply module converts 100 to 120 VAC input power into a +5.1 VDC output for connected control hardware. With a rated output current of 29 A and a stated output power of 147.9 W, it supplies DC power to compatible system components. Confirm the mounting position, backplane interface, and electrical compatibility with the target system before installation.

Hardware Specifications

DC Power Output and Electrical Compatibility

The PW701 is specified for AC input and regulated DC output. The +5.1 VDC output and 29 A rated current define the stated output operating point. Before connecting the module, verify the required supply voltage, maximum current demand, connector assignment, and system-specific power distribution requirements.

The supplied specifications do not establish support for hot swapping, redundant operation, or a particular backplane architecture. These functions require confirmation against the applicable Yokogawa hardware documentation.

Frequently Asked Questions

Q: What input and output ratings are specified for the PW701?

A: The supplied data specifies a 100 to 120 VAC input at 50/60 Hz, a 4.0 A input current, and a +5.1 VDC output rated at 29 A.

Q: Is the PW701 suitable for redundant power supply configurations?

A: The supplied information does not confirm redundancy support. Verify the target system configuration and manufacturer documentation before using the module in a redundant arrangement.

Q: Can the PW701 be replaced while the system is energized?

A: Hot-swap capability is not confirmed by the supplied data. Isolate power and follow the applicable system maintenance procedure unless the manufacturer explicitly authorizes live replacement.

Field Installation Guidelines

1. Verify identification: Check the module label and confirm the exact PW701 variant against the equipment documentation.
2. Inspect electrical ratings: Confirm that the AC input source matches the specified voltage and frequency.
3. Check output requirements: Verify that the connected load operates at +5.1 VDC and remains within the rated current capacity.
4. Inspect connectors: Check the module and mating connectors for damage, contamination, or loose contacts before installation.
5. Maintain wiring separation: Route AC input wiring separately from sensitive analog signal and communication wiring where the equipment design permits.
6. Confirm grounding: Follow the manufacturer's grounding and protective-earth requirements for the installed system.
7. Verify operation: After installation, check the output voltage and system status using the approved commissioning procedure.
