The TECNED GR(HS) series is a modular industrial rectifier and battery charger system engineered for reliable DC power applications requiring high availability, low maintenance, and continuous operation. Designed for utilities, infrastructure, data centres, and industrial environments, the GR(HS) series combines modular architecture, natural cooling technology, and advanced system supervision for maximum operational reliability.

Available for 24 Vdc, 48 Vdc, 110 Vdc, 125 Vdc, and 220 Vdc applications, the GR(HS) series features naturally cooled power modules without cooling fans or moving mechanical parts. This design significantly reduces maintenance requirements, minimizes mechanical wear, and eliminates failures associated with forced-air cooling systems.

The modular architecture with hot-swappable power modules allows fast replacement and maintenance without interrupting system operation. Combined with N+1 redundancy capability, the GR(HS) series provides enhanced system availability and operational continuity for mission-critical DC power installations.

The integrated LCD display provides real-time monitoring of operating values, alarm conditions, system parameters, and event logs, ensuring efficient supervision and simplified maintenance.
