Application of B25615A5287J301 in Port Crane Drives

Special Power Supply Requirements for Port Lifting Equipment

Port cranes are core equipment for container loading and unloading, with high work intensity and high automation. Crane drive systems need to provide precise torque control while being able to withstand frequent start-stop and load changes. DC-Link filter capacitors in drive systems need to quickly respond to power changes. Any power fluctuation may cause imprecise crane movements, resulting in safety accidents.

TDK-EPCOS B25615A5287J301 Solution

B25615A5287J301 is a heavy-duty aluminum electrolytic capacitor developed by TDK-EPCOS for port crane equipment drive systems, with a capacitance of 5287μF, featuring fast response and high ripple current bearing capacity. This product can maintain stable DC-Link voltage during frequent load changes of cranes, providing reliable filtration support for variable frequency drive systems.

Key Product Advantages

Fast Dynamic Response: B25615A5287J301 has ultra-low ESR, can quickly respond to power changes during crane lifting and lowering processes, ensuring sensitive drive system response and precise control.

Large Ripple Current Bearing Capacity: Crane variable frequency converters have large switching ripple. This product can withstand high ripple current, maintaining stable filtration effects under various working conditions.

Impact Resistant Design: Can withstand voltage and current surges during emergency crane stops and starts, extending capacitor service life.

Long-Life Reliability: Can operate stably for long periods in port salt spray environments, with service life exceeding 3,000 hours, reducing maintenance costs.
