Configured for power distribution in industrial control platforms, the Yokogawa PS13*B (PS13*B Power Supply Module) provides direct physical/electrical execution of voltage regulation and system power delivery.

Suffix Breakdown & Model Matrix

The PS13*B series utilizes a flexible suffix structure to designate specific input/output voltage configurations and power output capacities. Consult the system hardware manual to match the specific model suffix with the required backplane power load and input voltage source.

Hardware Specifications

Power Regulation and System Stability

The module functions as a primary DC power source, providing stable voltage regulation to the backplane bus and connected I/O hardware. To ensure long-term operational consistency, the unit incorporates internal surge protection and output filtering to mitigate electrical noise generated by upstream power grid fluctuations. The modular design enables efficient heat dissipation, supporting continuous operation under the varying electrical loads typically encountered in process control cabinets.

Frequently Asked Questions

Q: Can multiple PS13*B modules be connected in parallel for current sharing?

A: Parallel operation is subject to the specific backplane design and module revision. Verify the system technical documentation to determine if the hardware supports active current sharing or if blocking diodes are required to prevent back-feeding between units.

Q: How is the thermal load managed during high-demand periods?

A: The module relies on passive convection cooling within the cabinet. Ensure that the specified installation clearances are maintained to prevent thermal accumulation and premature degradation of internal components.

Field Installation Guidelines

1. Verify that the incoming power source matches the input voltage rating of the specific PS13*B model suffix before connecting the primary power leads.
2. Route high-voltage AC input lines separately from low-voltage DC output and signal cabling to prevent electromagnetic interference (EMI).
3. Secure the module onto the rack or DIN rail, ensuring a low-impedance electrical bond is established between the chassis and the system protective earth (PE) ground.
4. Measure the output voltage at the backplane terminals under no-load conditions to confirm operational status before connecting the control system modules.
5. Inspect the wiring connections periodically to ensure that terminal screws remain tightened, mitigating the risk of high-resistance contact points.
