Power distribution units (PDUs) are the backbone of any organized electrical installation, serving as the central hub for distributing electrical power from a primary source to multiple downstream devices. These units, often referred to as distribution boards, panelboards, or load centers depending on regional terminology, are designed to handle specific voltage and current ratings, typically ranging from 100A to 630A or higher. Key technical specifications include the number of poles (e.g., 3P, 4P), rated operational voltage (e.g., 400V AC), rated insulation voltage, and short-circuit withstand capacity. PDUs integrate essential components like main switches, busbars, and outgoing feeder protection, ensuring safe and efficient power distribution in industrial environments.
PDUs are deployed across a wide range of sectors, including manufacturing plants, data centers, commercial buildings, and infrastructure projects. In industrial automation, they are installed within main distribution boards (MDBs) or sub-distribution boards (SDBs) to power motor control centers (MCCs), variable frequency drives (VFDs), and programmable logic controllers (PLCs). They are also critical in renewable energy systems, such as solar farms and wind turbines, where they manage power from inverters to grid connections. Their modular design allows for easy integration into existing electrical networks, supporting both fixed and plug-in configurations.
Our catalog includes several subcategories of PDUs, such as fixed-type distribution boards, modular distribution boards, and intelligent PDUs with remote monitoring capabilities. Key article codes include the PDU-100 series for basic applications and the PDU-400 series for high-current installations. The article code structure typically follows a pattern like PDU-[Amperage]-[Poles]-[Version], for example, PDU-250-3P-A, where '250' indicates the rated current in amperes, '3P' denotes three poles, and 'A' represents the revision level. Other relevant codes include the PDU-630-4P-B for heavy-duty industrial use.
