Introduction

1.Main Functions

Convert the input AC voltage into multiple stable DC output voltages to supply power for other control boards, signal acquisition circuits and logic units inside the SYNPOL D system.
Provide overvoltage, undervoltage, overcurrent and short-circuit protection to prevent damage to the whole control system when power abnormalities occur.
Monitor the real-time status of power outputs, feed back fault signals to the main controller for alarm and diagnosis.www.plcva.com
Filter power supply noise and suppress electromagnetic interference, ensuring clean and reliable power for the precision control circuits of the SYNPOL D system.
Support hot standby power redundancy coordination in some SYNPOL D configurations.

2.Applications

The CMA131B power board belongs to the ABB SYNPOL D series, which is a turbine control system mainly used for steam turbine and gas turbine governor, protection and excitation control.www.plcva.com

It acts as the internal power source core of the SYNPOL D turbine control cabinet.
Applied in power plants (thermal power, combined cycle power station), industrial power generation units.
Supplies regulated power to turbine speed control, valve control, protection logic and measuring signal boards.
Guarantees continuous and stable operation of turbine control equipment under industrial site power fluctuation conditions.
Used for new unit commissioning, spare part replacement and maintenance of existing SYNPOL D turbine control systems.plcva.com
