Yokogawa CP332D CENTUM VP Power Supply Unit
The Yokogawa CP332D, also cataloged as the CP332D Power Supply Unit, operates as a dedicated hardware component for AC-to-DC power conversion and voltage regulation within Yokogawa CENTUM VP rack assemblies. The module converts 100/200/240 VAC wide-range input supply into a tightly regulated DC output adjustable from 1 V to 40 V up to 30 A, delivering ripple-suppressed power to internal controller backplanes and system I/O buses.

4-20 mA HART & Fieldbus Communication Protocols
The Yokogawa CP332D power supply unit incorporates channel-to-channel isolation topology to isolate primary AC utility lines from secondary DC system buses, preventing high-voltage transients and common-mode electrical noise from propagating into sensitive DCS processing nodes. Low-ripple output filtering (less than 1 mV RMS) maintains signal power purity across backplane rails, shielding downstream 4-20 mA HART analog input cards and Fieldbus interface modules against high-frequency switching interference.
Frequently Asked Questions
Q: Does the CP332D power supply support parallel redundancy in system racks?
A: Yes, the CP332D supports optional parallel operation configurations, enabling current sharing and power redundancy across dual power supply modules in a single rack assembly.
Q: What protective features prevent over-voltage damage to downstream I/O hardware?
A: The module includes integrated overvoltage protection circuits that clamp output power lines and shut down supply rails if output potential exceeds rated threshold limits.
Field Installation Guidelines
- Ensure primary AC supply lines (100/200/240 VAC) are de-energized and locked out before wiring terminal connections to the CP332D input blocks.
- Mount the module securely into a standard 19-inch 3U rack space, ensuring all panel chassis screws are tightened to establish protective earth grounding.
- Route AC input power lines in separate conduit paths from low-voltage DC output lines and sensitive 4-20 mA instrument cabling to avoid electromagnetic interference.
- Maintain unrestricted vertical cooling airflow above and below the 3U module rack to ensure ambient enclosure temperatures do not exceed the 0 deg C to +40 deg C operational limit.
