920-0077A Product Overview

The GUTOR 920-0077A is a high-reliability industrial modular DC charger, developed by GUTOR Electric Ltd—a Switzerland-based expert in critical power solutions under the APC Group. Specifically engineered for demanding applications in power substations, industrial plants, and renewable energy storage systems, it serves as a core power supply for battery banks, ensuring stable charging and backup power support for control systems, protection relays, and emergency equipment. A standout feature is its N+X redundant design, allowing multiple power modules to operate in parallel—if one module fails, others automatically take over without interrupting the load, achieving an availability rate of 99.99%. Equipped with advanced power factor correction (PFC) technology, it minimizes input harmonic distortion (THDi ≤5%) and maximizes energy efficiency (up to 95%), reducing operational costs and easing the burden on upstream power grids. The “hot-swap” capability of its power modules enables on-site maintenance without shutting down the entire system, while support for multiple battery types (lead-acid, NiCd, Li-ion) and wide input voltage range ensures flexible adaptation to diverse industrial environments.
