Application Scenarios

• Continuous Casting Machines: In the steel industry, continuous casting machines require frequent adjustments in casting speed, resulting in significant regenerative energy during motor start-stop cycles. The BDPS-11C power supply board provides stable 24V DC power to the frequency converter’s control unit, ensuring precise consumption of regenerative braking energy. This reduces surface crack rates in cast billets by 40% and saves over 2 million yuan in annual quality losses.
• Cranes: When lifting heavy loads, cranes require rapid braking to prevent overloading. The BDPS-11C power supply board ensures millisecond-level response in braking torque control, reducing equipment failure rates by 50% and cutting annual maintenance costs by 800,000 yuan.
• Wind Turbines: Wind turbines need to convert unstable wind energy into constant-frequency alternating current. The BDPS-11C power supply board provides isolated power to the IGBT drive circuit, preventing control signal interference caused by grid voltage fluctuations and improving power generation efficiency by 3%.
