Battery-Backed Industrial DC Systems

DC Systems – Power Center

KraftPowercon Power Center PC05 and PC10 are modular industrial DC systems designed to provide reliable battery-backed power for switchgear, relay protection, control equipment, process control, and other critical auxiliary loads. Each system integrates rectifiers, batteries, battery fuse protection, distribution boards, and monitoring in a compact cabinetized solution for high availability and easy service.

The Power Center is suited for power plants, electricity distribution, substations, and industrial facilities where uninterrupted DC power is critical for safe operation. Hot-swap rectifier modules, battery temperature monitoring, float voltage control, battery circuit testing, symmetry monitoring, and optional redundant configurations help reduce risk, simplify maintenance, and improve long-term reliability.
