Main features and advantages
High-efficiency power conversion: FOXBORO P0970BP adopts advanced zero-voltage switching (ZVS) technology, achieving a conversion efficiency of up to 92% and significantly reducing heat generation during operation.
Its active power factor correction (PFC) function ensures that the input power factor is greater than 0.95. effectively reducing harmonic pollution to the power grid. In a large-scale petrochemical project in Guangdong, this feature helped users save over 4.000 kilowatt-hours of electricity annually.
Intelligent redundancy architecture: The module supports N+1 redundancy configuration. When a power failure is detected, the system can achieve seamless switching within 20ms to ensure that the power supply to the DCS system is not interrupted.
The digital current sharing technology of FOXBORO P0970BP ensures load balancing among multiple parallel modules. In a power plant project in Fujian, this redundant design successfully avoided the impact of power grid fluctuations caused by lightning strikes on the DCS system.
Comprehensive protection functions: Built-in multiple protection functions such as overvoltage, overcurrent, short circuit and overheating ensure the safety of power supply and load equipment.
The overload protection feature of “voltage reduction first, then shutdown” of FOXBORO P0970BP prevents the load equipment from being damaged due to sudden power interruption.
In the lightning strike incident at a chemical plant in Shandong Province, this protection function successfully prevented the control system worth millions of yuan from being damaged.
Application field
FOXBORO P0970BP is widely used in process industries, especially in DCS systems with extremely high requirements for power supply quality.
In large-scale integrated refining and chemical plants, this power module provides pure and stable power for key control circuits, ensuring the safe and stable operation of the plant.
Its rapid fault switching capability (<20ms) ensures the continuous operation of the control system in abnormal situations such as power grid fluctuations or lightning strikes.
